Aspartic acid (symbol Asp or D; [4] the ionic form is known as aspartate), is an α-amino acid that is used in the biosynthesis of proteins. [5] The L -isomer of aspartic acid is one of the 22 proteinogenic amino acids , i.e., the building blocks of proteins .

In practice, a protein with an excess of basic aminoacids (arginine, lysine and/or histidine) will bear an isoelectric point roughly greater than 7 (basic), while a protein with an excess of acidic aminoacids (aspartic acid and/or glutamic acid) will often have an isoelectric point lower than 7 (acidic).
Aspartic proteases (also "aspartyl proteases", "aspartic endopeptidases") are a catalytic type of protease enzymes that use an activated water molecule bound to one or more aspartate residues for catalysis of their peptide substrates. In general, they have two highly conserved aspartates in the active site and are optimally active at acidic pH.
The pH-dependence of the activity displayed by enzymes and the pH-dependence of protein stability, for example, are properties that are determined by the pK a values of amino acid side chains. The p K a values of an amino acid side chain in solution is typically inferred from the p K a values of model compounds (compounds that are similar to ...
Asn-Gly (NG),is the most flexible and since it is acidic, it is most prone to deamidation with a half-life around 24 h under physiological conditions (pH 7.4, 37 °C). [3] As a free amino acid, or as the N-terminal residue of a peptide or protein, glutamine deamidates readily to form pyroglutamic acid (5-oxoproline). The reaction proceeds via ...
The protein is 472 amino acids long and has a calculated molecular weight of 53kDa. Its isoelectric point is approximately a pH of 7.0. [11] [14] In addition, there is an increased abundance of cysteine, aspartic acid, and serine residues. [15] Its increased abundance of serine may contribute to its ability to be hyperphosphorylated.
Aspartic acid (aspartate) is one of the most common amino acids in the typical diet. As with methanol and phenylalanine, intake of aspartic acid from aspartame is less than would be expected from other dietary sources. [10] [51] At the 90th percentile of intake, aspartame provides only between 1% and 2% of the daily intake of aspartic acid. [10]
