Differences in chemical composition between the epithelial glycoproteins of the upper and lower halves of rat colon.


Analysis of the apparently homogeneous sulfated sialoglycoproteins isolated from the epithelial cells of the upper (proximal to the ileum) and lower (proximal to the rectum) halves of Wistar rat colon showed that whereas they were similar in overall carbohydrate and amino acid composition, they differed significantly in the O-acetyl substitution pattern of… (More)
