MODULE 8: VITAMINS AND MINERALS Water vs Fat Soluble Vitamins -fat soluble: A, D,E,K •can be stored, need falt to be absorbed - water soluble •depleted at higher rates, no storage, excreted in urine •more likely to accumulate toxic concentration, more likely to be defquent Factors that Affect Vitamin Requirements -lifestages growing animals higher req, makes them more susceptible to toxicity -health/disease interaction •anhbiotics •digestion, absorption, turnover, synthesis Importance of Vitamins as coenzymes needed for metabolic reactions -4 required coenzymes thiamine pyrophosphate (TPP)→ BI •lipok aud body coenzyme Apantothenk aad FAD→riboflavin NAD-niaan Vitamin C -2 active forms: •ascorbic aud/ascorbate •dehydroascorbic aud (DHA) -role of glucose L-gulunolactone oxidase 4 •help in synthesis of VHC -funcion: collagen synthesis •AA metabolism •antioxidant activity •iron absorption •Immune function Thiamin -2 active forms •thiamine diphosphate (TOP) •thiamine pyrophosphate (TPP) - role as a coenzyme - • used for decarboxylation of pyruvate Vitamin A -forms/functions -need for dietary fat Three Main Functions of Minerals
