Why cannot vitamin C be stored in our body?
Vitamin C (Ascorbic acid) is a water soluble versatile vitamin. Humans cannot synthesize vitamin C due to the deficiency of a enzyme L- gulonolactone oxidase and also vitamin C is rapidly absorbed from the intestine. Because it is water soluble vitamin it is not stored in the body to a significant extent. As a result, it is readily excreted in the urine. Vitamin C is excreted as such or as its metabolite diketogulonic acid and oxalic acid in urine
