Identification
Name:Phosphoserine
DescriptionPhosphoserine is phosphoric acid ester of serine. As a constituent (residue) of proteins, its side chain can undergo O-linked glycosylation. It is one of three amino acid residues that are commonly phosphorylated by kinases during cell signalling. Phosphorylated serine residues are often referred to as phosphoserine.
