Sugar giant peptides: help the baby resist flu virus

1965 Delfour found κ-casein of milk-clotting enzymes cut in a particular location, generated under κ-casein and insoluble 12% trichloroacetic acid (TCA) GMP of soluble molecule [6]. GMP in the amino acid composition of aromatic amino acids are missing, and branched-chain amino acids are many. GMP sugar chains are mainly of a combination of new-type glucoside 2 and 3 neutral sugar chain acid sugar chain, more than 90% combination of sugar chains with sialic acid.
