Urinary ascorbic acid excretion and sugar consumption as indices of enzyme induction and hypoglycemia in recovering alcoholic rats
… and recovery periods and analyzed for L-ascorbic acid. The mean consumption of sucrose was highest for rats still receiving alcohol and declined in all groups during the 10 days. The mean consumption of sucrose (% kcal as sucrose) for the first 4 days was 33.2, 19.5, 19.0, and 13.8% for …

Investigation of the potential molecular recognition sites of two human vitamin C transporters.
Vitamin C (L-ascorbic acid), a cofactor for numerous mammalian enzymes and a well- known antioxidant, is renowned for its range of health advantages and protective capabilities against degenerative disorders. The mechanisms regulating the cellular movement of ascorbic acid signify a primary aspect …

Thin films of non-peripherally substituted liquid crystalline phthalocyanines A
… nicotinamide adenine dinucleotide (NADH) and L-ascorbic acid (vitamin C) were carried out using optical absorption spectroscopy. Thin films of a non-peripherally octyl substituted LC lead phthalocyanine was exposed to 99.9 % pure hydrogen sulfide gas to produce hybrid nanocomposites consisting …
