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. Its α-amino … Visa mer Aspartic acid was first discovered in 1827 by Auguste-Arthur Plisson and Étienne Ossian Henry by hydrolysis of asparagine, which had been … Visa mer Biosynthesis In the human body, aspartate is most frequently synthesized through the transamination Visa mer Aspartate has many other biochemical roles. It is a metabolite in the urea cycle and participates in gluconeogenesis. It carries reducing equivalents in the malate-aspartate shuttle, … Visa mer There are two forms or enantiomers of aspartic acid. The name "aspartic acid" can refer to either enantiomer or a mixture of two. Of these two forms, only one, "L-aspartic acid", is directly incorporated into proteins. The biological roles of its counterpart, "D … Visa mer In plants and microorganisms, aspartate is the precursor to several amino acids, including four that are essential for humans: methionine, threonine, isoleucine, and Visa mer In 2014, the global market for aspartic acid was 39.3 thousand short tons (35.7 thousand tonnes) or about $117 million annually with potential areas of growth accounting for an addressable market of $8.78 billion (Bn).

At its pI, the positive and negative charges on the amino acid balance, and the molecule as a whole is electrically neutral. The amino acids whose side chains are always neutral have isoelectric points ranging from 5.0 to 6.5.
WebbThe neutral form of aspartic acid is dominant between pH 1.88 and 3.65, thus the isoelectric point is halfway between these two values, i.e. 1/2 (pKa1 + pKa3), so isoelectric point will be 2.77.
