The alternative direct hydrolysis pathway (Asn → Asp) is also operative at this pH. Additionally, there is a minor Isoimide-mediated pathway that may also contribute to deamidation under our experimental conditions (Asn → Isoimide ⇌ Asp).

Aspartic acid has an acidic side chain (CH 2 COOH) which reacts with other amino acids, enzymes and proteins in the body. Under physiological conditions (pH 7.4) in proteins the side chain usually occurs as the negatively charged aspartate form, −COO −. It is a non-essential amino acid in humans, meaning the … Visa mer Aspartic acid (symbol Asp or D; the ionic form is known as aspartate), is an α-amino acid that is used in the biosynthesis of proteins. Like all other amino acids, it contains an amino group and a carboxylic acid.
