Document Summary
Bioavailability how well the vitamin is absorbed. Found mostly in meats, alternatives, grains and fruits and veg. Thiamin burns cho for energy: too little beriberi (muscle weakness and nerve damage) B6 pyridoxine protein and aa metabolism and hemoglobin synthesis: too little neurological symptoms, anemia. Folate dna synthesis/ new cell formation: crucial in pregnancy, spina bifida when spinal cord is not completely inside the vertebrae, anencephaly part of the brain missing. Help in dna synthesis and some hormones. Oxidation stealing of electrons (by free radicals), molecules that contain oxygen are the. Absorption is maxed by consuming iron-rich foods with foods high in vit c. Antioxidants compounds that protect our cells from damage caused by oxidation stealers. Free radical when atoms pair up with unpaired electrons and remain unpaired. What can be oxidized: oxidation in the body, other metabolic processes, pollution, over exposure to sun, etc, cell membrane phospholipids, dna, low density proteins (ldl, proteins, if they"re oxidized they don"t work.
