aspartic acid

 [ah-spahr´tik]
a dibasic amino acid, one of the nonessential amino acids, widely distributed in proteins and found as an excitatory neurotransmitter in the central nervous system.

as·par·tic ac·id (Asp),

(as-par'tik as'id),
The l-isomer is one of the amino acids occurring naturally in proteins. The d-isomer is found in cell walls of many bacteria.

aspartic acid

/as·par·tic ac·id/ (ah-spahr´tik) a nonessential, natural dibasic amino acid occurring in proteins and also an excitatory neurotransmitter in the central nervous system. Symbols Asp and D.

aspartic acid

(ə-spär′tĭk)
n.
A nonessential amino acid, C4H7NO4, found especially in young sugarcane and sugar-beet molasses.

aspartic acid (Asp)

[aspär′tik]
a nonessential amino acid present in sugar cane, beet molasses, and breakdown products of many proteins. Pure aspartic acid is a water-soluble, colorless crystalline substance. Aspartic acid is interconvertible with oxaloacetic acid from the citric acid cycle. Aspartic acid is used in culture media, dietary supplements, detergents, fungicides, and germicides. Also called aminosuccinic acid. See also amino acid, protein.

aspartic acid or aspartate (D, Asp)

one of 20 AMINO ACIDS common in proteins. It has an extra carboxyl group and is therefore acidic in solution. The ISOELECTRIC POINT of aspartic acid is 2.8.
