| BCAA | branched chain amino acid |
|---|---|
| BCT | brachiocephalic trunk; branched-chain amino acid transferase |
| CAAX [box] | protein segment in which C is cysteine, A is usually but not always an aliphatic amino acid, and X i... |
| EAAC | excitatory amino acid carrier |
| Fd | the amino-terminal portion of the heavy chain of an immunoglobulin molecule; ferredoxin |
| crotonic acids | 2-butenoic acids. 4-carbon monounsaturated monocarboxylic acids with the unsaturation in the 2 position. (12 Dec 1998) |
|---|---|
| saturated fatty acids | In eukaryotic membranes refers to stearic, palmitic and myristic acids, that are linear aliphatic chains with no double bonds. Prokaryotes have numerous branched chain saturated fatty acids. (18 Nov 1997) |
| propionic acids | 3-carbon saturated monocarboxylic acids. (12 Dec 1998) |
| heptanoic acids | 7-carbon saturated monocarboxylic acids. (12 Dec 1998) |
| prostanoic acids | 2-octylcyclopentaneheptanoic acids. The family of saturated carbon-20 cyclic fatty acids that represent the parent compounds of the prostaglandins. (12 Dec 1998) |
| hexuronic acids | Term used to designate tetrahydroxy aldehydic acids obtained by oxidation of hexose sugars, i.e. Glucuronic acid, galacturonic acid, etc. Historically, the name hexuronic acid was originally given to ascorbic acid. (12 Dec 1998) |
| pteroylpolyglutamic acids | Derivatives of folic acid (pteroylglutamic acid). In gamma-glutamyl linkage they are found in many tissues. They are converted to folic acid by the action of pteroylpolyglutamate hydrolase or synthesised from folic acid by the action of folate polyglutamate synthetase. Synthetic pteroylpolyglutamic acids, which are in alpha-glutamyl linkage, are active in bacterial growth assays. (12 Dec 1998) |
| humic acids | <chemical> Allomelanins found in soils, coals, and peat, resulting from the decomposition of organic matter, particularly dead plants. They are a mixture of complex macromolecules having polymeric phenolic structures with the ability to chelate metals, especially iron. (merck index, 11th ed) Pharmacological action: chelating agents. Chemical name: Humic acids (12 Dec 1998) |
| hydroxamic acids | A class of weak acids with the general formula r-conhoh. (12 Dec 1998) |
| hydroxy acids | Organic compounds containing both the hydroxyl and carboxyl radicals. (12 Dec 1998) |
| hydroxybenzoic acids | Benzoic acid substituted by one or more hydroxy groups in any position on the benzene ring. (12 Dec 1998) |
| hydroxyeicosatetraenoic acids | Eicosatetraenoic acids substituted in any position by one or more hydroxy groups. They are important intermediates in a series of biosynthetic processes leading from arachidonic acid to a number of biologically active compounds such as prostaglandins, thromboxanes, and leukotrienes. (12 Dec 1998) |
| sialic acids | A group of naturally occurring n-and o-acyl derivatives of the deoxyamino sugar neuraminic acid. They are ubiquitously distributed in many tissues. (12 Dec 1998) |
| naphthaleneacetic acids | Naphthalene derivatives containing the -ch2cco2h radical at the 1-position, the 2-position, or both. Compounds are used as plant growth regulators to delay sprouting, exert weed control, thin fruit, etc. (12 Dec 1998) |
| stearic acids | A group of compounds that are derivatives of octadecanoic acid which is one of the most abundant fatty acids found in animal lipids. (12 Dec 1998) |
