Document Summary

Part of co-enzyme tpp (thiamin pyrophosphate) which works with pdh (pyruvate dehydrogense) = oxidation of. Beriberi chronic thiamin deficiency, weakness (less atp from cellular respiration), and weight loss. Brown rice (white rice is thiamin deficient) Part of co-enzyme fmn, fad (electron acceptors for atp pathway) Ariboflavinosis inflammation of membranes (mouth, eyes, gi system, skin) 4x rda ~ 35mg); blood flow increased, painful tingling sensation. Part of co-enzyme pyruvate carboxylase makes oxaloacetate from pyruvate (krebs) Caused by eating too much egg whites. Raw egg white has avidin, which binds to biotin and decreases bioavailability. Part of co-enzyme a makes acetyl coa. Protein metabolism of 11 non-essential amino acids (acts as coenzyme) Blood cell synthesis + o2 binding to hemo. Reduced risk of myocardial infarction (plp dependent enzymes convert homocysteine to cysteine = reduced plaque formation) Microcytic hypochromic anemia: rbc smaller and lacks hb. Toxicity: 1000-2000mg = protein modification (can lead to nerve damage) Amino acid metabolism, dna synthesis, cell division.
