title: Studies of folic acid compounds in nature. IV. Folic acid compounds in soybeans and cow milk.
abstract: Folate compounds in soybean and cow's mild were identified by Sephadex chromatography and differential microbiological assaymsoybean contained mainly monoglutamates (ca. 52%), some diglutamates (ca. 16%), and polyglutamates (pentaglutamates representing the major portion). 5-CHO-H4PteGlun(1-6) constituted 65-70% of total folate activity; Cow's milk contained monoglutamates (60%) and polyglutamates (ranging from di- to hepta-conjugates). In contrast to soybean, 90-95% of milk folate was in the 5-CH3h4pteGlun(1-7) form.
