Goat, colostrum

C12H23NO10 341.314 Isol. from porcine gastric mucin, human milk, glycoproteins with human blood group A activity, goat colostrum and from fetuin. Growth factor for Lactobacillus bifidus. [a]g- +78.2 (3 min) +63.1 (3h) (c, 1.25 in H2O). 

A new, computer-aided, 3D heteronuclear n.m.r. technique (3D TOCSY HECTOR) for H- and C-chemical shift assignments has been applied to raffinose as model. The structures of the four neutral trisaccharides 26-29 from goat colostrum have been elucidated by g.c. analysis of hydrolysis products and... 

A particulate sialyltransf erase preparation from rat mammary gland and soluble preparations from goat colostrum and pork liver were assayed in the presence of a variety of possible sialic acid acceptors. The conditions of assay were saturating for both acceptor and donor and the activities therefore represent relative Vm values. Activities are corrected for the small amount of endogenous acceptor activity usually present. 

The rat mammary gland enzyme makes predominantly sialyl-(23)-lactose, the goat colostrum enzyme makes sialyl-(26)-lactose (Roseman et al., 1966), and the pork liver enzyme makes both sialyl-(23)-lactose and sialyl-(26)-lactose (Hudgin and Schachter, 1972).

The nucleotide-oligosaccharides belong to an interesting class of compounds. In goat colostrum, the following species containing sialic acids have been identified (Jourdian et aL, 1961 Jourdian and Roseman, 1963) ...
