Monosaccharide composition of the serum of normal and estrogen-treated male birds

Gas liquid chromatography using a methylation and silylation technique is a viable method for the quantitative determination of monosaccharides in serum. Analyses of sera of normal and estrogen-treated birds by this method indicated that estrogen administration increased uronic acid, fucose, galactose, mannose, and sialic acid contents and decreased glucose content of the serum. The greatest of the above increases was that of uronic acid.
