Abstract

About 80 per cent of the population secretes soluble blood group substances with A, B, and O(H) specificities corresponding to each individual's blood type; the remaining 20 per cent, the "nonsecretors," do not.'Most nonsecre- tors, however, do secrete large amounts of Lea-specific blood group substance, a glycoprotein similar in composition to the A, B, and O(H) substances of secre- TABLE 1.Some oligosaccharides of human milk.6.7 Compound I.
