Influence of controlled strenuous exercise on vitamin B-6 metabolism in man : effects of carbohydrate depletion-repletion diets and vitamin B-6 supplements

Creator:: Hatcher, Lauren Francis
Abstract:: Recent studies in men have shown plasma levels of vitamin B-6 and pyridoxal 5'-phosphate (PLP), the active form of vitamin B-6, to increase with exercise. It was hypothesized that muscle glycogen phosphorylase might be the source of these increases as this enzyme has been shown to increase with increasing vitamin...

The effect of vitamin B-6 deficiency on carnitine metabolism during fasting in rats

Creator:: Cho, Youn-ok
Abstract:: The purpose of this study was, first, to investigate whether there is a vitamin B-6 requirement for carnitine synthesis and, second, to investigate the effect of fasting on vitamin B-6 metabolism. An experimental group of 72 rats (6 per group) were fed either a vitamin B-6 deficient diet (-B6) (ad...

Changes in plasma pyridoxal 5'-phosphate and red blood cell pyridoxal 5'-phosphate concentration during an oral glucose tolerance test in persons with diabetes mellitus

Creator:: Martinson, Kerry Elizabeth
Abstract:: The purpose of this study was to determine the relationship between the overall changes in concentration of plasma pyridoxal 5'-phosphate (PLP), red blood cell PLP (rbc PLP) and plasma glucose during an oral glucose tolerance test (OGTT) in persons with diabetes mellitus (DM), and to test the hypothesis that the...

In vivo and in vitro assessment of vitamin B6 bioavailability in humans

Creator:: Kabir, Gholamhossein
Abstract:: Bioavailability (BA) of vitamin B6 (B-6) from foods may be limited. The knowledge of the BA of B6 from food is important in that this would help to understand if the B6 present in the diet of individuals will meet the requirements for this vitamin. The purpose of this study...

Carbohydrate loading, vitamin B-6 supplementation, and fuel metabolism during exercise of differing intensity in post-absorptive man

Creator:: DeVos, Ann
Abstract:: Four young trained men were studied during 50 min of continuous bicycle ergometer exercise [30 min at 60%, 15 min at 80%, and 5 min at 90% maximal heart rate (MHR)] to elucidate changes in fuel metabolism resulting from a glycogen depletion-repletion regimen, and to determine the effect of supplemental...

The effect of vitamin B-6 supplementation on fuel utilization and plasma amino acids during exhaustive endurance exercise in men

Creator:: Virk, Ricky S.
Abstract:: Previous studies suggest that vitamin B-6 supplementation can alter fuel metabolism during exercise and plasma amino acid levels at rest. To examine the effect of vitamin B-6 supplementation on plasma fuel substrates and amino acid levels during exercise, five trained males (age: 29±7; V0₂ max: 54.7±6.2 ml/kg/min) performed two separate...

Vitamin B-6 status of persons with diabetes mellitus

Creator:: Smith, Daniel E.
Abstract:: The status of vitamin B-6 (B6) nutriture of nine persons (4F;5M) with insulin dependent diabetes mellitus (IDDM), nine persons (5F;4M) with non-insulin dependent diabetes mellitus (NIDDM), and 18 control individuals (9F;9M) was evaluated, using biochemical and dietary indicators of B6 status. The biochemical indices employed were plasma concentration of pyridoxal...

The effect of two levels of glucose ingestion on plasma pyridoxal 5'-phosphate concentration

Creator:: Huang, Ying-Hui
Abstract:: This study was designed to evaluate the effect of glucose on plasma pyridoxal 5'- phosphate (PLP) concentration. The objective was to determine whether there was a negative relationship between glucose ingestion and plasma PLP concentration and to evaluate the possible mechanism of decreased PLP after acute glucose ingestion. Seven healthy...

Determination of vitamin B-6 and pyridoxine-glucoside in selected Malawi foods and the effect of preparation techniques on vitamin B-6 and pyridoxine-glucoside content

Creator:: Kaunda, Jean R.
Abstract:: There were two main purposes to this study. The first was to determine the vitamin B-6 and pyridoxine β-glucoside content of selected foods commonly consumed in Malawi. The second was to examine the effect of preparation procedures of foods in Malawi on the content of vitamin B-6 and pyridoxine β-...

Vitamin B-6 metabolism and status in young and middle-aged women

Creator:: Lee, Caroll Marie
Abstract:: To investigate the responses of healthy adult women to two levels of vitamin B-6, a seven week two-part experiment was conducted with five young adults and eight middle-aged subjects. During the four unsupplemented weeks, dietary vitamin B-6 was 2.3-2.4 mg/day. In the final three weeks, the same diet was supplemented...
