Webphosvitin: ( fos-vī'tin ), A phosphated protein constituting about 7% of the protein of egg yolk; it is about 60% serine, largely as O -phosphoserine, and has anticoagulant properties; an anticoagulant. Synonym(s): phosphovitin WebPhosvitin contains a relatively high amount of phosphorous and strongly binds multivalent cations such as iron and calcium. The ability of phosvitin to bind heavy metal ions supports antioxidant activity and protects against lipid oxidation.
WebPhosphovitin is a phosphoglycoprotein and represents the major protein component of egg yolk. It contains 6.5% carbohydrate which consists of 6 hexose residues, 5 glucosamine residues, and 2 sialic acid residues per molecule. The carbohydrate moiety is bound through an asparagine residue (N-linked). WebMar 1, 2024 · Phosvitin peptides are not easy to obtained, due to the phosvitin molecule has consecutive phosphoserine residues that can interfere with the formation of the proper enzyme-substrate complex needed for hydrolysis.

[ 1] This phosphoglycoprotein comprises α-helices and β-sheets structural elements, which are poorly organized due to the presence of phosphoserine. [ 1] It represents about 11% of yolk proteins and is hydrophilic. [ 2]
WebIntroduction. Phosvitin (PV), one of the highly phosphorylated proteins in nature, is produced by proteolytic cleavage of chicken vitellogenin (a metal-binding protein), which is disseminated in the hen blood and picked up by developing oocytes (Richards, 1997).Vitellogenin is cleaved into lipovitellin and PV yolk proteins, sometimes during or …
