| 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 |
| nicotinic acids | 2-, 3-, or 4-pyridinecarboxylic acids. Pyridine derivatives substituted with a carboxy group at the 2-, 3-, or 4-position. The 3-carboxy derivative (niacin) is active as a vitamin. (12 Dec 1998) |
|---|---|
| succinic acids | A class of dicarboxylic acids with the general structure of butanedioic acid (succinic acid). They are used in perfumery and as a chemical intermediate in medicine. (12 Dec 1998) |
| sugar acids | Acids, such as gluconic, glycuronic, and saccharic acid, produced by the oxidation of glucose. (05 Mar 2000) |
| sulfanilic acids | Aminobenzenesulfonic acids. Organic acids that are used in the manufacture of dyes and organic chemicals and as reagents. (12 Dec 1998) |
| nucleic acids | Highly complex portions of nucleoproteins that yield a mixture of purines and pyrimidines, a ribose or deoxyribose component, and phosphoric acid on complete hydrolysis. The two general types are ribonucleic acid (RNA) and deoxyribonucleic acid (DNA). (12 Dec 1998) |
| nucleic acids, nucleotides, and nucleosides | Complex compounds of high molecular weight occurring in living cells. These are basically of two types, ribonucleic (RNA) and deoxyribonucleic (DNA) acids, both of which consist of nucleotides (nucleoside phosphates linked together by phosphate bridges). (12 Dec 1998) |
| sulfenic acids | Oxy acids of sulfur with the general formula rsoh, where r is an alkyl or aryl group such as ch3. They are often encountered as esters and halides. (12 Dec 1998) |
| sulfinic acids | Any of the monobasic inorganic or organic acids of sulfur with the general formula rso(oh). (12 Dec 1998) |
| sulfonic acids | Inorganic or organic oxy acids of sulfur which contain the rso2(oh) radical. (12 Dec 1998) |
| sulfur acids | Inorganic or organic acids that contain sulfur as an integral part of the molecule. (12 Dec 1998) |
| sulfuric acids | Inorganic and organic derivatives of sulfuric acid (h2so4). The salts and esters of sulfuric acid are known as sulfates and sulfuric acid esters respectively. (12 Dec 1998) |
| decanoic acids | 10-carbon saturated monocarboxylic acids. (12 Dec 1998) |
| docosahexaenoic acids | C22-unsaturated fatty acids found predominantly in fish oils. (12 Dec 1998) |
| imino acids | Compounds with molecules containing both an acid group (usually the carboxyl, -COOH) and an imino group (==NH); e.g., proline, hydroxyproline. (05 Mar 2000) |
| indoleacetic acids | Acetic acid derivatives of the heterocyclic compound indole. (merck index, 11th ed) (12 Dec 1998) |
