| tricarboxylic acids | Organic compounds that are acyclic and contain three acid groups. A member of this class is citric acid which is the first product formed by reaction of pyruvate and oxaloacetate. (12 Dec 1998) |
|---|---|
| erucic acids | Cis-13-docosenoic acids. 22-carbon monounsaturated, monocarboxylic acids. (12 Dec 1998) |
| essential amino acids | Alpha-amino acids nutritionally required by an organism and which must be supplied in its diet (i.e., cannot be synthesised by the organism) either as free amino acid or in proteins. (05 Mar 2000) |
| excitatory amino acids | Endogenous amino acids released by neurons as excitatory neurotransmitters. Glutamic acid is the most common excitatory neurotransmitter in the brain. Aspartic acid has been regarded as an excitatory transmitter for many years, but the extent of its role as a transmitter is unclear. (12 Dec 1998) |
| ketoglutaric acids | A family of compounds containing an oxo group with the general structure of 1,5-pentanedioic acid. (12 Dec 1998) |
| uronic acids | Acids derived from monosaccharides by oxidation of the primary alcohol group (-CH2OH) farthest removed from the carbonyl group to a carboxyl group (-COOH); e.g., glucuronic acid. (05 Mar 2000) |
| lauric acids | 12-carbon saturated monocarboxylic acids. (12 Dec 1998) |
| levulinic acids | Keto acids that are derivatives of 4-oxopentanoic acids (levulinic acid). (12 Dec 1998) |
| linoleic acids | Eighteen-carbon essential fatty acids that contain two double bonds. (12 Dec 1998) |
| linolenic acids | Eighteen-carbon essential fatty acids that contain three double bonds. (12 Dec 1998) |
