Document Summary
Required in small quantities (mg, mcg, etc. ) Most function as catalysts/ coenzymes (figure 8. 5 in textbook) Their removal from the diet produces a known deficiency disease (cured by adding. Fat soluble vitamins: that vitamin back to the diet) Therefore excess intake is possible and can result in liver toxicity. Required as a coenzyme for enzymes involved in energy production, especially from carbohydrate. As part of two coenzymes: tpp and tdp: food sources of thiamin. Meat, grain products, white flour (thiamin is added back by law along with riboflavin, niacin, folate and iron: thiamin deficiency. Still occurs in certain places where refined grains (rice) are eaten (ex. Western world- alcoholics alcohol breakdown: b1 is required as a coenzyme for enzymes involved in, decreased absorption of b1, tend to have a poor diet. Symptoms: muscle weakness, neurological changes and coordination, tingling, numbness. Involved in enzyme processes where glucose and fatty acids are converted to energy.
