| receptors, amino acid | Cell surface proteins that bind amino acids and trigger changes which influence the behaviour of cells. Glutamate receptors are the most common receptors for fast excitatory synaptic transmission in the vertebrate central nervous system, and gaba and glycine receptors are the most common receptors for fast inhibition.

| glucogenic amino acid | <biochemistry> A type of amino acid with carbon chains that can be broken down into an intermediate of the citric acid cycle such as glycogen and then converted into glucose as a means of entering the normal process of carbohydrate metabolism in the body. Examples include: Glycine, alanine, arginine, and ornithine. (14 Oct 1997) |
| RNA, transfer, amino acid-specific | A group of transfer rnas which are specific for carrying each one of the 20 amino acids to the ribosome in preparation for protein synthesis. (12 Dec 1998) |
| polar amino acid | An alpha-amino acid in which the functional group attached to the alpha-carbon (i.e., R in RCH(NH2)COOH) has hydrophilic properties; e.g., serine, cysteine, homocysteine. (05 Mar 2000) |
| sequence homology, amino acid | The degree of similarity between sequences of amino acids. This information is useful for the understanding of genetic relatedness of certain species. (12 Dec 1998) |
