Aspartic Acid Theβ-carboxylic acid group ofaspartic acidhas a pK′ of 3.86 and is ionized at pH 7.0 (the anionic form is calledaspartate). The anionic carboxylate groups tend to occur on the surface of water-soluble proteins, where they interact with water. Such surface interactions stabilize...

Stability constants of Am (III) and U(VI) with L-aspartic acid have been determined at pH 8.00 by means of the solvent extraction technique. It was found that Am (III) forms 1 : 1 and 1 : 2 complexes while U(VI) formed only the 1 : 1 complex under these conditions. The ...
Two aspartic acid residues that cleave the substrate regulates the catalytic mechanism. Pepsin, a digestive enzyme is reported to be the first enzyme of this class. Their activity is maximum between pH range of 1–5, and first 3-dimensional structure of aspartic proteases was identified...
