Vitamin C is soluble in water, slightly soluble in ethanol, insoluble in ether, benzene,oils, fats.The aqueous solution reacts with acidity. In the air can be quickly oxidized to dehydroascorbic acid, citric acid like taste.It is a strong reducing agent, which gradually turns ...
An association has been shown between the leucocyte ascorbic-acid levels and the activity of the principal enzyme concerned in ethanol metabolism, alcohol dehydrogenase. Further studies have demonstrated that the rate of clearance of ethanol from the blood is associated with increased levels of leucocyte...
