The effect of dietary glycosylated vitamin B-6 on the bioavailability
of vitamin B-6 was determined in 4 women. A 44-d metabolic-balance diet
study was divided into a preliminary 8-d adjustment period followed by
two 18-d experimental periods. The subjects were divided into two groups
in a crossover design to compare...
The bioavailability of vitamin B₆ in four selected foods
(bananas, filberts, soybeans and beef) was determined in five men,
aged 22 to 25 years, who were saturated with pyridoxine. The study
consisted of a five-day adjustment period followed by a 28-day experimental
period. All subjects consumed a constant diet containing...
The purposes of the research presented in this thesis were: (1)
to determine the precision with which it is possible to measure
changes in vitamin B6 compounds in the blood and urine following
oral doses of levels of vitamin B6 (as pyridoxine) which are in the
range of the normal...
Pyridoxal phosphate is a coenzyme in about 50 known enzymatic
reactions. A simple and accurate method for the determination of
pyridoxal phosphate would be desirable because it could provide a
means to assess the nutritional status of vitamin B₆ in the human.
The cyanohydrin methods to determine pyridoxal phosphate appear...
In two studies we tested the effect of vitamin B-6
(B-6) intake on in vitro lymphocyte, proliferation and IL-2
production in healthy young women. In Study I, 6 women were
fed a constant diet containing 0.84 mg (4.96 μmols) of B-6
for 12 d, and 1.24 mg (7.33 μmols) and...
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...
