PPT-Is a water soluble vitamin and easily destroyed by heat, alkali and storage .In the process

The vitamin is easily oxidized to form dehydroascorbic acid DHAA and thus oxidation is readily reversible Vitamin C is a generic name for all compounds that exhibit the same biologic activity as AA Consequently the term includes both AA and DHAA The structure formula of vitamin CAscorbic acid closely resembles that of carbohydrates. B 12 is also a cofactor in two metabolic pathways specifically the conversion of homocysteine to methionine and the conversion of methylmalonic acid MMA to succinylCoA Sources of B 12 include animal products such as meat fish poultry shellfish and m C2- Chemistry.
