What is Glycine?
Glycine is the aboriginal of the amino acids. It is ambivalent, acceptation that it can be central or alfresco of the protein molecule. In aqueous band-aid at or abreast aloof pH, glycine will abide predominantly as the zwitterion
The isoelectric point or isoelectric pH of glycine will be centered amid the pKas of the two ionizable groups, the amino accumulation and the carboxylic acerbic group.
In ciphering the pKa of a anatomic group, it is important to accede the atom as a whole. For example, glycine is a acquired of acerb acid, and the pKa of acerb acerbic is able-bodied known. Alternatively, glycine could be advised a acquired of aminoethane.
