Abstract
Folate compounds in soybean and cow's milk were identified by Sephadex chromatography and differential microbiological assay. Soybean 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-CH3-H4PteGlun(1–7) form.Keywords
