Pyridoxine-5'-beta-D-glucoside affects the metabolic utilization of pyridoxine in rats
Article Abstract:
The effects of dietary 5'-O-(beta-D-glucopyranosyl)pyridoxine (PN-glucoside) on the metabolic utilization of co-administered pyridoxine in rats were investigated. The results showed that PN-glucoside could alter the metabolism and in vivo retention co-injested pyridoxines. In addition, PN-glucosides could also inhibit the utilization of nonglycosylated forms of vitamin B-6. Since PN-glucosides constitute a significant part of total vitamin B-6 in many plant-derived foods, these results have implications in the proper assessment of vitamin B-6 availability in a typical mixed diet.

Molybdenum requirement of female rats
Article Abstract:
Molybdenum (Mo) is an essential element in human and animal nutrition. However, the level of Mo requirement in humans have not yet been established. The criteria for the assessment of nutritional status of Mo were established and the Mo requirement in female rats were determined. The experiments showed that Mo status can be best assessed by analyzing the activities of Mo-containing enzymes such as xanthine dehydrogenase/oxidase, sulfite oxidase and aldehyde oxidase. A value of 0.200 grams per kilogram diet was estimated as the dietary requirement for Mo in female rats.

In vivo folate kinetics during chronic supplementation of human subjects with deuterium-labeled folic acid
Article Abstract:
The turnover kinetics of folate in the body was studied by giving deuterium-labeled folic acid supplements to human subjects. Gas chromatography mass-spectrometry and microbiological assays were utilized to assess folate concentration in blood and urine. The results showed that folate concentration varied directly to supplementation. Turnover rate was at 4.5% of the folate pool per day. A two pool theory was formulated to explain folate turnover in the body, introducing the concepts of rapid and slow turnover fractions.
