NUTR 120 Lecture Notes - Lecture 21: Pyridoxal Phosphate, Premenstrual Syndrome, Folate Deficiency
Document Summary
Part of 2 coenzynmes: nad and nadp to help get kcal from cho, fat, protein. Meat and alternatives and grain products are good sources of niacin.

Corn has a lot of niacin but we get access to it once we soak it in a basic solution, e. g. *any kind of meat is a good source of b vitamins. *milk products are not good for b vitamins, except for b2 and b12 lime. Function: converted to active b6: plp (pyridoxal phosphate) Plp is coenzyme in reactions of protein metabolism. E. g. formation of heme ring: has fe at the very center surrounded by nitrogen. Conversion of trp niacin (b6 requiring reaction)
