As indicated, an acidic amino acid is one that contains within its residue a carboxylic acid group symbolized by--C(O)OH (see Chart 5).
The acidic amino acids contain in their residues a carboxylic acid group, the basic amino acids contain at least one nitrogen atom, and the neutral amino acids have hydrocarbon residues (composed of only hydrogen and carbon) that may also include sulfur or nitrogen.
a, acidic amino acid (E or D); x, any amino acid; PG, proteoglycan.
Comparison of amino acid sequences of chondroitin sulfate attachment sites in different proteoglycans (Table 1) led to a consensus sequence--a-a-a-x-S-G-x-G--with at least one acidic amino acid "a" and variable amino acids "x".
Under physiologic conditions, large amounts of EAAS are stored in intracellular compartments; the EAA concentrations in the cytoplasm of brain cell are conspicuously higher than those in the extracellular space, a gradient maintained by acidic amino acid carriers present in both presynaptic and glial plasma membranes.

According to the present invention, a cDNA can be obtained encoding the amino acid sequence of aminopeptidase GX suitable for producing a highly hydrolized product from a starting material containing a protein and peptide having a high acidic amino acid content.
The differences found for the acidic amino acids (aspartic and glutamic acids) and glycine between tissue and shell organic matter suggest these compounds may not be ideal for direct interpretation of dietary signals when soft tissue analogs are unavailable (i.

The results of amino acid composition (Table 2) showed that the purple ink contains high levels of acidic amino acids, glutamic, and aspartic acid and very low content of sulfur amino acids.
Our analysis of amino acid composition showed that the purple ink is rich in acidic amino acids and has very low content of sulfur amino acids, reflecting the amino acid composition of both seaweeds (Ramos et al.
