· Which nutrients if deficient may cause Beriberi, Ariboflavinosis, Pellagra, and Scurvy? Which deficiency is also known as the “4 D’s” and what are the symptoms?
· Primary function of B vitamins (coenzymes)
· Water soluble vitamins on which to focus:
§ Niacin (may also be derived from which specific amino acid?; which other B vitamin is necessary for this conversion?; also used as a supplement for high cholesterol)
§ B-6 (why is B-6 more likely to be toxic if overconsumed?)
§ B-12 (what is required for B-12 to be absorbed and where is it produced?; what is pernicious anemia and how is it treated?
§ Folate (what is the relationship to neural tube defects?; how can an anemia of folate deficiency be caused by B-12?)
· What are the main functions of Vitamin C? What are signs/symptoms of a Vit C deficiency?
Chapter 11
· Why are fat soluble vitamins more likely to cause toxicity and less likely to induce a deficiency than water soluble vitamins? Through which circulatory system do they travel?
· Vit A (retinoid): 3 active forms; main function (vision); most common Vit A deficiency symptom? food sources of pre-formed vitamin A and provitamin A (beta-carotene)? What is the major effect of consuming large amounts of beta-carotene from food sources?
· Vit D (calciferol); common sources (foods and sunlight); what two organs play a role in activating Vit D (by adding hydroxyl groups); main function (bone growth and maintenance); deficiency condition in children and adults
· Vit E (tocopherol): main function (antioxidant)
· Vit K: main function is in blood clotting; source of Vit K other than food (intestinal bacteria); why is a newborn given a dose of Vit K?
