Chloroethane, commonly known as ethyl chloride, is a chemical compound with chemical formula CH3CH2Cl, once widely used in producing tetraethyllead, a gasoline additive. It is a colorless, flammable gas or refrigerated liquid with a faintly sweet odor.
Palmitic acid, or hexadecanoic acid in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and other dairy products. Palmitates are the salts and esters of palmitic acid. The palmitate anion is the observed form of palmitic acid at physiologic pH (7.4).
Ethyl oleate is a fatty acid ester formed by the condensation of oleic acid and ethanol. It is a colorless to light yellow liquid. Ethyl oleate is produced by the body during ethanol intoxication.
Ethyl acetate is the organic compound with the formula CH

2. This colorless liquid has a characteristic sweet smell and is used in glues, nail polish removers, and in the decaffeination process of tea and coffee. Ethyl acetate is the ester of ethanol and acetic acid; it is manufactured on a large scale for use as a solvent.
The chemical compound ethyl nitrite is an alkyl nitrite with a chemical formula C2H5NO2. It may be prepared from ethanol.
Ethyl formate is an ester formed when ethanol reacts with formic acid. Ethyl formate has the characteristic smell of rum and is also partially responsible for the flavor of raspberries. It occurs naturally in the body of ants and in the stingers of bees.
Retinyl palmitate, or vitamin A palmitate, is the ester of retinol (vitamin A) and palmitic acid, with formula C36H60O2. It is the most abundant form of vitamin A storage in animals.
Ascorbyl palmitate is an ester formed from ascorbic acid and palmitic acid creating a fat-soluble form of vitamin C. In addition to its use as a source of vitamin C, it is also used as an antioxidant food additive. It is approved for use as a food additive in the EU, the U.S., Canada, Australia, and New Zealand.
Etilamfetamine is a stimulant drug of the phenethylamine and amphetamine chemical classes. It was invented in the early 20th century and was subsequently used as an anorectic or appetite suppressant in the 1950s, but was not as commonly used as other amphetamines such as amphetamine, methamphetamine, and benzphetamine, and was largely discontinued once newer drugs such as phenmetrazine were introduced. It most likely acts primarily as a dopamine releasing agent. Its activity as a norepinephrine or serotonin releasing agent is not known.

Palmitoyl protein hydrolase/thioesterases are enzymes (EC 3.1.2.22) that remove thioester-linked fatty acyl groups such as palmitate from modified cysteine residues in proteins or peptides during lysosomal degradation. It is an enzyme that catalyzes the chemical reaction
In enzymology, a retinyl-palmitate esterase (EC 3.1.1.21) is an enzyme that catalyzes the chemical reaction
The molecular formula C18H36O2 (molar mass: 284.48 g/mol, exact mass: 284.2715 u) may refer to:
Ethyl iodoacetate is a chemical compound that is a derivative of ethyl acetate. Under normal conditions, the compound is a clear, light yellow to orange liquid.
Propetandrol (INN), or propethandrol, also known as 17α-ethyl-19-nortestosterone 3β-propionate or 17α-ethyl-19-nor-4-androstenediol 3β-propionate, as well as 17α-ethylestr-4-en-3β,17β-diol 3β-propionate, is a synthetic and orally active anabolic–androgenic steroid (AAS) and progestogen and a 17α-alkylated derivative of 19-nortestosterone. It is an androgen ester – specifically, the 3β-propionate ester of norethandrolone (17α-ethyl-19-nortestosterone).
Azinphos-ethyl was a broad-spectrum organophosphate insecticide.
Estradiol palmitate, or estradiol monopalmitate, also known as estradiol 17β-hexadecanoate, is a naturally occurring steroidal estrogen and an estrogen ester – specifically, the C17β palmitate ester of estradiol. It occurs in the body as a very long-lasting metabolite and prohormone of estradiol. The compound has no affinity for the estrogen receptor, requiring transformation into estradiol for its estrogenic activity. In addition to its endogenous role, estradiol palmitate was formerly used as a fattening agent in chickens under the brand name Esmopal.
Lipoidal estradiol (LE2) is the variety of endogenous C17β long-chain fatty acid esters of estradiol which are formed as metabolites of estradiol. Important examples of these esters include estradiol arachidonate, estradiol lineolate, estradiol oleate, estradiol palmitate, and estradiol stearate. LE2 are estrogens but do not bind to the estrogen receptor, instead acting as prohormones of estradiol. Relative to estradiol, they have far longer-lasting durations of effect due to their much slower rates of metabolism and clearance. It has been hypothesized that LE2 may serve as a store of estrogen for when estradiol levels become low. LE2 are highly lipophilic and hydrophobic and are found in highest concentrations in adipose tissue and other estrogen-sensitive tissues and in low but detectable concentrations in circulation, with none excreted in urine. They have been referred to as the "endogenous counterparts of the synthetic esters of estrogens" like estradiol valerate and estradiol cypionate.
