Vitamin C deficiency - or hypovitaminosis C defined as a plasma concentration below 23 μm - is estimated to affect hundreds of millions of people in the Western world, in particular subpopulations of low socio-economic status that tend to eat diets of poor nutritional value. Recent studies by us have shown that vitamin C deficiency may result in impaired brain development. Thus, the aim of the ...

Alcoholic liver disease (ALD) is a serious liver problem in western countries. Our previous study has demonstrated that vitamin C plays a protective role in ALD. The vitamin C homeostasis is tightly regulated by sodium-dependent vitamin C transporters (SVCTs) 1 and 2. But the role of two SVCTs in ALD is less understood. In this study, we examined the expression patterns of two SVCTs in mice aft...

the aim of current study was to determine the effects of vitamin c on bone mineral density (in terms of osteoporosis), eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. one hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin c (0, 250, 500 and 750 mg/kg diet). the experimental desi...

Vitamin C serves as a cofactor in the synthesis of collagen needed to support cardiovascular function, maintenance of cartilage, bones, and teeth, as well as being required in wound healing. Although vitamin C is essential, humans are one of the few mammalian species unable to synthesize the vitamin and must obtain it through dietary sources. Only low levels of the vitamin are required to preve...

Marked variations in the vitamin C content of different varieties of apples have been observed. The values of 21 Massachusetts-grown varieties were reported by Smith and Fellers,^ and the results of several other workers have been summarized by Batchelder.^ Between different lots of apples of the same variety small differences in vitamin C concentration have been found which appeared to result ...

natural citrus biotypes are a valuable genetic resource in the country. investigation about diversity of biochemical compounds due to optimize the utilization and development of new varieties is useful. therefore, for identifying them, the fruits of 16 biotypes with numbers of 6, 8, 15, 21, 24, 25, 26, 29, 30, 41, 43, 45, 48, 51, 52 and 53 in the germplasm collection of the iran citrus research...

Processed fruits and vegetables have been long considered to have lower nutritional value than their fresh commodities due to the loss of vitamin C during processing. This research group found vitamin C in apples contributed < 0.4% of total antioxidant activity, indicating most of the activity comes from the natural combination of phytochemicals. This suggests that processed fruits and vegetabl...

Ceramide is the most abundant lipid in the epidermis and plays a critical role in maintaining epidermal barrier function. Overall ceramide content in keratinocyte increases in parallel with differentiation, which is initiated by supplementation of calcium and/or vitamin C. However, the role of metabolic enzymes responsible for ceramide generation in response to vitamin C is still unclear. Here,...
