glycine
Product Detailed
Related Categories:Organic Intermediate
Synonyms: Glycocol, Aminoacetic acid
CAS No.: 56-40-6
Molecular Weight: 75.07
Chemical Formula: CH2NH2 COOH
Glycine is the smallest of the amino acids. It is ambivalent, meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH, glycine will exist predominantly as the zwitterion
The isoelectric point or isoelectric pH of glycine will be centered between the pKas of the two ionizable groups, the amino group and the carboxylic acid group.
In estimating the pKa of a functional group, it is important to consider the molecule as a whole. For example, glycine is a derivative of acetic acid, and the pKa of acetic acid is well known. Alternatively, glycine could be considered a derivative of aminoethane.
