摘要: SummaryThe storage of vit. B12 in rat liver was investigated after feeding rats graded levels crystalline or crude supplements. The B12M potency determined with L. leichmannii short-term auto-claving the homogenates at pH 7.0. shown to increase as level fed increased. values were only 1/10 1/20 those for beef liver, however, and not reduced appreciably by alkali treatment. Studies on desoxyribonucleic acid livers studies Euglena gracilis assays indicated that activity remaining, treatment, may be due presence stable forms well desoxyribosides. weight greater per unit body B12-deficient diet compared optimum diet.
