Since the discovery of vitamin C, the number of its known biological functions is continually expanding. Both the names ascorbic acid and vitamin C reflect its antiscorbutic properties due to its role in the synthesis of collagen in connective tissues. Ascorbate acts as an electron-donor keeping ...

Ascorbic acid (ascorbate/AsA/vitamin C) is one of the most abundant and versatile biomolecules in plants and animals. In particular, AsA is present in high concentrations in the chloroplasts and cytosol of plant species. In plants, AsA serves as a major antioxidant and enzyme cofactor and regul...
Extensive reviews of research are available on the use of ascorbic acid, and its consequent degradation pathways, in physiological conditions or food matrices. However, very little information can be found for wine-related systems. This review highlights the relevant chemistry and reactivity of ascorbic...
