Document Summary
The functions of b-6 include: homocysteine metabolism, synthesis of nonessential amin oacids, synthesis of neurotransmitters. A compound that combines with an inactive enzyme to form an active enzyme is called a coenzyme. Functions of ribo avin include assisting antioxidant reactions and the release of energy from fatty acids. The b vitamins play a role in metabolism by acting as coenzymes. Compared to re ned or processed grains, whole grains contain more ber, zinc, and magnesium. The coenzyme form of pantothenic acid participates in release of energy from carbohydrates, fats, and proteins, and fatty acid synthesis. The coenzyme form of vitamin b-6 participates in more than 100 amino acid metabolism reactions, including homocysteine metabolism. Ribo avin plays a role in the body"s antioxidant defense system as a coenzyme for glutathione peroxidase. During the enrichment of re ned grain products, iron is the only mineral added, whereas the selenium, zinc, copper, and other minerals lost during re nement are not replaced.
