WebIn this lab, we will focus on the pH buffering capabilities of the protein Glycine, one of the most widespread amino acid found in human enzymes. Carboxyl group (a-COOH) and the amino group (a-NH 3 ) are two ionizable groups of Glycine that can either donate or accept protons. The ionization of these two groups often take part in the formation ... WebHLA-B27 is a serologically-defined allele of the human HLA-B locus.
