Relationship between vitamin B12 oxidation product and sodium chloride toxicity for lactobacilli.
Beiler et al. (1951) reported that oxidation of vitamin B12 by hydrogen peroxide under strongly acid conditions resulted in the production of a colorless product which inhibited the vitamin B12 requiring microorganism, Lactobacillus leichmannii (ATCC 4797). Such inhibition was antagonized competitively by vitamin B12. Since we had observed that hydrogen peroxide itself competitively inhibited g...

The Na,(+) Cl(-), and K(+) content of toad plasma and the sartorius muscle has been determined. Although the Na(+) and Cl(-) level of the muscles in the living animal varied greatly (0 to 38.0 m.eq. per kg., and 0 to 31.8 m.eq. per kg. respectively) the K(+) level was subject to a smaller variation (76.5 to 136 m.eq. per kg.). There was a direct relationship between Na(+) and Cl(-), which was i...

Association between Vitamin B 12 Levels and Melancholic Depressive Symptoms
Background An association between vitamin B12 levels and depressive symptoms (DS) has been reported in several epidemiological studies. The purpose of this study was to evaluate vitamin B12 levels in populationbased samples with melancholic or non-melancholic DS as the relationship between vitamin B12 levels and different subtypes of DS has not been evaluated in previous studies. Methods Subjec...
متن کاملVitamin B-12.
V itamin B-12 is a cofactor for 2 enzymes. In the cytoplasm, methionine synthase requires vitamin B-12 in the form of methylcobalamin and catalyzes the conversion of homocysteine to methi-onine by transfer of a methyl group from methyltet-rahydrofolate. This enzyme links the methylation pathway through synthesis of the methyl donor S-adenosyl methionine and the pathway in which purine and pyrim...
