Hydroxypyruvic acid is the organic compound with the formula HOCH2C(O)CO2H. It is a white solid. It is encountered in many biochemical contexts, being the oxidized derivative of lactic acid, a degradation product of RuBisCO, and the result of oxidative deamination of serine. [2]
The citric acid cycle (CAC) – also known as the TCA cycle or the Krebs cycle – is a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins. The Krebs cycle is used by organisms that respire to generate energy, either by anaerobic respiration or aerobic respiration. In addition, the cycle provides precursors of certain amino acids, as well as the reducing agent NADH, that are used in numerous other reactions. Its central importance to many biochemical pathways suggests that it was one of the earliest components of metabolism and may have originated abiogenically. Even though it is branded as a 'cycle', it is not necessary for metabolites to follow only one specific route; at least three alternative segments of the citric acid cycle have been recognized.
An ester is a chemical compound derived from an acid in which at least one –OH hydroxyl group is replaced by an –O– alkyl (alkoxy) group, as in the substitution reaction of a carboxylic acid and an alcohol. Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils.
In chemistry, carbonic acid is a dibasic acid with the chemical formula H2CO3. The pure compound decomposes at temperatures greater than ca. −80 °C.
Citric acid is an organic compound with the chemical formula HOC(CO2H)(CH2CO2H)2. It is a colorless weak organic acid. It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms.
Berberine is a quaternary ammonium salt from the protoberberine group of benzylisoquinoline alkaloids found in such plants as Berberis, such as Berberis vulgaris (barberry), Berberis aristata, Mahonia aquifolium, Hydrastis canadensis (goldenseal), Xanthorhiza simplicissima (yellowroot), Phellodendron amurense, Coptis chinensis, Tinospora cordifolia, Argemone mexicana, and Eschscholzia californica. Berberine is usually found in the roots, rhizomes, stems, and bark.

Acetic acid, systematically named ethanoic acid, is an acidic, colourless liquid and organic compound with the chemical formula CH3COOH. Vinegar is at least 4% acetic acid by volume, making acetic acid the main component of vinegar apart from water and other trace elements.
Glyoxylate and dicarboxylate metabolism describes a variety of reactions involving glyoxylate or dicarboxylates. Glyoxylate is the conjugate base of glyoxylic acid, and within a buffered environment of known pH such as the cell cytoplasm these terms can be used almost interchangeably, as the gain or loss of a hydrogen ion is all that distinguishes them, and this can occur in the aqueous environment at any time. Likewise dicarboxylates are the conjugate bases of dicarboxylic acids, a general class of organic compounds containing two carboxylic acid groups, such as oxalic acid or succinic acid.
D-Glyceric Acidemia is an inherited disease, in the category of inborn errors of metabolism. It is caused by a mutation in the gene GLYCTK, which encodes for the enzyme glycerate kinase.
4-Hydroxymandelic acid is a chemical compound used to synthesize atenolol. The compound typically occurs as a monohydrate.
Wayne M. Becker is emeritus professor of Botany at the University of Wisconsin and, under the name W. M. Becker, the original author, and for the next six editions, senior author of The World of the Cell (Pearson). Becker first joined the University of Wisconsin in 1958 and obtained his PhD in 1967. He received his B.S, M.S., and Ph.D in biochemistry at this college. Becker spent two years in the United Kingdom as a NATO/NIH postdoctoral researcher, and then returned to the campus in 1969 as a member of the Botany Department Faculty. He also spent a year in the same position at the University of Edinburgh.
