Biochimica et Biophysica Acta (BBA) is a peer-reviewed scientific journal in the field of biochemistry and biophysics that was established in 1947. The journal is published by Elsevier with a total of 100 annual issues in ten specialised sections.
Biochimica et Biophysica Acta was first published in 1947 and was the first international journal to be devoted to the joint fields of biochemistry and biophysics.Published by Elsevier in cooperation with Interscience, it was the first international journal to be launched by Elsevier. The journal first made a profit in 1951.
Early papers were published in English, French, and German, with summaries in all three languages. [ original research? ]The majority of papers in the first volume originated in northern and western Europe, with a minority from the US and elsewhere; contributors included William Astbury, Jean Brachet, Hubert Chantrenne, Pierre Desnuelle, Claude Fromageot, Heinz Holter, Raymond Jeener, Felix Haurowitz, Edgar Lederer, Kaj Linderstrøm-Lang, Roger Vendrely, Jean-Marie Wiame, and Ralph W.G. Wyckoff.
Important papers from these early years include "Studies on the structure of ribonucleic acids" by Boris Magasanik and Erwin Chargaff (1951),part of the evidence on which Watson and Crick's model of the structure of DNA was based, and "Enzymic synthesis of deoxyribonucleic acid" by Arthur Kornberg and colleagues (1956), an early report on the isolation of DNA polymerase I.
Biochimica et Biophysica Acta was published as a single title until 1962, when additional sections began to be published alongside the main journal: first Specialized Section on Nucleic Acids and Related Subjects and then, from 1963, Specialized Section on Enzymological Subjects and Specialized Section on Lipids and Related Subjects.
In 1964, the main journal became Biochimica et Biophysica Acta (BBA) – General Subjects, and was published alongside the three established sections plus Specialized Section on Biophysical Subjects and Specialized Section on Mucoproteins and Mucopolysaccharides. In 1965, the specialist sections were renamed, becoming Biophysics including Photosynthesis, Nucleic Acids and Protein Synthesis, Enzymology and Biological Oxidation, Lipids and Lipid Metabolism and Mucoproteins and Mucopolysaccharides (ceased in 1965). In 1967, Biophysics including Photosynthesis split into Bioenergetics and Biomembranes, and Enzymology and Biological Oxidation split into Enzymology and Protein Structure; the latter pair rejoined in 1982 to become Protein Structure and Molecular Enzymology. Further sections were Molecular Cell Research, launched in 1982, and Molecular Basis of Disease, launched in 1990.
In addition to the specialised research sections, three review sections were launched in the early 1970s: Reviews on Biomembranes (1972–2000), Reviews on Bioenergetics (1973–87) and Reviews on Cancer (from 1974). The former two were later incorporated into the respective research sections.
Further name changes are given in the table in the following section.
As of 2014, Biochimica et Biophysica Acta encompasses ten specialised sections with a total of 100 annual issues in ten volumes. Over 16,000 pages were published in 2011. The journal sections are published separately, with one annual volume per section (two for Reviews on Cancer), but form part of the volume numbering for Biochimica et Biophysica Acta.Sections are available individually or as part of a combined subscription. All papers are in English. The overall editor-in-chief is Ulrich Brandt (Goethe University Frankfurt, Germany).

P700, or photosystem I primary donor, is the reaction-center chlorophyll a molecule in association with photosystem I. Its name is derived from the word “pigment”, and the maximal wavelength of light it can absorb, 700 nm, at which the phenomenon of photobleaching would occur. Its absorption spectrum peaks at 700 nm. The structure of P700 consists of a heterodimer with two distinct chlorophyll molecules, most notably, chlorophyll a and chlorophyll a’, giving it an additional name of “special pair”. Inevitably, however, the special pair of P700 behaves as if it were just one unit. This species is vital due to its ability to absorb light energy with a wavelength approximately between 430 nm-700 nm, and transfer high-energy electrons on to enzymes that are situated subsequent to it.
In biology, membrane fluidity refers to the viscosity of the lipid bilayer of a cell membrane or a synthetic lipid membrane. Lipid packing can influence the fluidity of the membrane. Viscosity of the membrane can affect the rotation and diffusion of proteins and other bio-molecules within the membrane, there-by affecting the functions of these things.
Peridinin is a light-harvesting apocarotenoid, a pigment associated with chlorophyll and found in the peridinin-chlorophyll-protein (PCP) light-harvesting complex in dinoflagellates, best studied in Amphidinium carterae.
Phosphatidylglycerol is a glycerophospholipid found in pulmonary surfactant and in the plasma membrane where it directly activates lipid-gated_ion_channels.
In enzymology, a hepoxilin-epoxide hydrolase is an enzyme that catalyzes the conversion of the epoxyalcohol metabolites arachidonic acid, hepoxilin A3 and hepoxilin B3 to their tri-hydroxyl products, trioxolin A3 and trioxilin B3, respectively. These reactions in general inactivate the two biologically active hepoxilins.
Protein–lipid interaction is the influence of membrane proteins on the lipid physical state or vice versa.
CYP4F22 is a protein that in humans is encoded by the CYP4F22 gene.
Neutral lipid storage disease is a congenital autosomal recessive disorder characterized by accumulation of triglycerides in the cytoplasm of leukocytes, muscle, liver, fibroblasts, and other tissues. It commonly occurs as one of two subtypes, cardiomyopathic neutral lipid storage disease (NLSD-M), or ichthyotic neutral lipid storage disease (NLSD-I) which is also known as Chanarin–Dorfman syndrome), which are characterized primarily by myopathy and ichthyosis, respectively. Normally, the ichthyosis that is present is typically non-bullous congenital ichthyosiform erythroderma which appears as white scaling.
One of the most important properties of a lipid bilayer is the relative mobility (fluidity) of the individual lipid molecules and how this mobility changes with temperature. This response is known as the phase behavior of the bilayer. Broadly, at a given temperature a lipid bilayer can exist in either a liquid or a solid phase. The solid phase is commonly referred to as a “gel” phase. All lipids have a characteristic temperature at which they undergo a transition (melt) from the gel to liquid phase. In both phases the lipid molecules are constrained to the two dimensional plane of the membrane, but in liquid phase bilayers the molecules diffuse freely within this plane. Thus, in a liquid bilayer a given lipid will rapidly exchange locations with its neighbor millions of times a second and will, through the process of a random walk, migrate over long distances.
Biophysical chemistry is a physical science that uses the concepts of physics and physical chemistry for the study of biological systems. The most common feature of the research in this subject is to seek explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the supra-molecular structure of these systems.
Arachidonoyl serotonin is an endogenous lipid signaling molecule. It was first described in 1998 as being an inhibitor of fatty acid amide hydrolase (FAAH). In 2007, it was shown to have analgesic properties and to act as an antagonist of the TRPV1 receptor. In 2011, it was shown to be present in the ileum and jejunum of the gastrointestinal tract and modulate glucagon-like peptide-1 (GLP-1) secretion.
Lysophosphatidylinositol, or L-α-lysophosphatidylinositol, is an endogenous lysophospholipid and endocannabinoid neurotransmitter. LPI, along with its 2-arachidonoyl- derivative, 2-arachidonoyl lysophosphatidylinositol (2-ALPI), have been proposed as the endogenous ligands of GPR55.
1,2-Dioleoyl-sn-glycerophosphoethanolamine is a non-bilayer lipid that adopts non-lamellar reverse hexagonal structures.
Sunil Kumar Podder is an Indian molecular biologist and biophysicist, known for his biophysical studies on Ligand. Focusing his researches on the recognition processes in biological systems and its chemical specificity, he proposed a model for measuring the specificity using free energy of association of amino acids of proteins with nucleic acid bases. A former member of faculty at the department of biochemistry of the Indian Institute of Science where he taught from 1972 to 1997, and a life member of the Indian Biophysical Society, he has published several articles detailing his research findings in peer reviewed journals and has presented many papers. The Council of Scientific and Industrial Research, the apex agency of the Government of India for scientific research, awarded him the Shanti Swarup Bhatnagar Prize for Science and Technology, one of the highest Indian science awards, in 1982, for his contributions to biological sciences.
Roland Winter is a biophysical chemist who studies the structure, dynamics, energetics, and phase behavior of biological membranes and proteins. He is dean of the Department of Chemistry and Chemical Biology at Technical University of Dortmund, Germany.
Bitopic proteins are transmembrane proteins that span the lipid bilayer only one time. These proteins may constitute up to 50% of all transmembrane proteins, depending on the organism, and contribute significantly to the network of interactions between different proteins in cells, including interactions via transmembrane helices. They usually include one or several water-soluble domains situated at the different sides of biological membranes, for example in single-pass transmembrane receptors. Some of them are small and serve as regulatory or structure-stabilizing subunits in large multi-protein transmembrane complexes, such as photosystems or the respiratory chain.
SF-6847 is a uncoupling agent/protonophore. As of 1974 when it was discovered, its considered most powerful, with a potency over 1800x that of 2,4-dinitrophenol - the prototypical uncoupling agent, and about 3x the effectiveness of 5-chloro-3-tert-butyl-2'-chloro-4'-nitrosalicylanilide.
David G. Nicholls is Professor Emeritus of Mitochondrial Physiology at the Buck Institute for Research on Aging in Novato, California. His research focuses on chemiosmosis proposed by Peter D. Mitchell to couple the electron transport chain to ATP synthase. His explanation of chemiosmotic theory in the textbook Bioenergetics has become the standard text in the field. He was elected a Fellow of the Royal Society (FRS) in 2019 for "substantial contribution to the improvement of natural knowledge".
Substrate presentation is a biological process that activates a protein. The protein is sequestered away from its substrate and then activated by release and exposure of the protein to its substrate. A substrate is typically the substance on which an enzyme acts but can also be a protein surface to which a ligand binds. The substrate is the material acted upon. In the case of an interaction with an enzyme, the protein or organic substrate typically changes chemical form. Substrate presentation differs from allosteric regulation in that the enzyme need not change its conformation to begin catalysis.
