Vitamin C in its primary form of L-ascorbic acid
has a proven track record for improving aging skin.
Therefore, present work was undertaken to produce stable L-dopa from synthetic L-tyrosine specifically with particular reference to the productive effects of L-ascorbic acid
on the microbiological transformation.
Ideal for face application as it has 20% L-ascorbic acid
At the concentrations designated in this study, the extract had over 90% hydrogen peroxide-hydrolysis activity, which was similar to that of BHT or L-ascorbic acid
BHT, TOC, and L-ascorbic acid
were used as positive controls.
Development of an amperometric L-ascorbic acid
(Vitamin C) sensor based on electropolymerised aniline for pharmaceutical and food analysis.
Some of the human clinical trials have shown similar favorable results when applying a daily dose of L-ascorbic acid
treatment, but all of these studies involved small sample sizes.
Several factors such as age, exposure to environmental situations, stress, dietary and biochemical changes produce alteration of L-ascorbic acid
levels in body fluids (Cheng 1990, Kolb 1992).
So, scientists at North Carolina A&T State University wanted to determine the ability of L-ascorbic acid
and propyl gallate, alone or in combination with lactic acid, to inhibit the growth of E.
PAN indicator: is a mixture of sulfuric acid solution, ammonium sulfate, 1,10-phenanthroline solution (20%), L-ascorbic acid
solution (2%) and acetic-sodium acetate buffer (pH [approximately equal to] 4.
One of our studies revealed that, L-ascorbic acid
administration simultaneously with nickel sulphate improves nickel induced hyperglycaemia by boosting insulin sensitivity in rats and also improve liver glycogen content.
The objective of this study was to examine the effects of L-Ascorbic acid
, CH, WPC and GMP, on the growth and viability of probiotic bacteria in fermented milk made with L.
