What is Pyridoxine Vitamin ( B6- vitamin ) | Pyridoxal Vitamin ( B6 ) | vitamin Pyridoxamine | Vitamin B6

Pyridoxal phosphate is the active form and is a cofactor in many reactions of amino acid metabolism, including transamination, deamination, and decarboxylation.The B6 vitamins and coenzymes, of their metabolites and of many related synthetic compounds that often exhibit biological activity as substitutes for or as antagonists of the corresponding natural products. A number of trivial and semitrivial names, sometimes incorrect or ambiguous, have been coined for vitamin B6 derivatives and analogues, and several forms of abbreviated designations for these compounds have been introduced.

Vitamin B6 is one of the best-studied of all B vitamins and has one of the greatest varieties of chemical forms. The forms of this vitamin all begin with the letters “pyr,” and include pyridoxine, pyridoxal, pyridoxamine, pyridoxine phosphate, pyridoxal phosphate, and pyridoxamine phosphate. Vitamin B6, or pyridoxine, is a member of the water-soluble family of B complex vitamins. It’s required for protein and glucose metabolism and to make hemoglobin, a component of red blood cells that carries oxygen to all the parts of your body.

Activity was not restored after incubation of the proteins with pyridoxal. However, when the algae were cultured in the presence of the antimetabolite and vitamin B6, the isozymes were fully active. It appears that there is an absolute requirement for pyridoxal in the biosynthesis of algal phosphorylases, and that this requirement is more basic and probably occurred much earlier in the evolution of 4 glucosyltransferases than the requirement for adenosine monophosphate.

Functions:

It performs a wide variety of functions in your body and is essential for your good health. For example, vitamin B6 is needed for more than 100 enzymes involved in protein metabolism. It is also essential for red blood cell metabolism.The pyridoxamine drug, by the way, is designed to prevent the progression of diabetic nephrothapy. Most likely, the FDA will eventually approve the “drug” for that condition, even while claiming vitamin B6 supplements containing the very same chemical are useless and insert.

Pyridoxal phosphate, the metabolically active form of vitamin B6, is involved in many aspects of macronutrient metabolism, neurotransmitter synthesis, histamine synthesis, hemoglobin synthesis and function and gene expression. Pyridoxal phosphate generally serves as a coenzyme for many reactions and can help facilitate decarboxylation, transamination, racemization, elimination, replacement and beta-group interconversion reactions. The liver is the site for vitamin B6 metabolism.

Enzymes are proteins that help chemical reactions take place. Because vitamin B6 is involved with more than 100 enzymatic reactions, its function in the body is diverse and far reaching.Calories, protein, vitamins, and minerals are important to your immune defenses because they promote the growth of white blood cells that directly fight infections. Vitamin B6, through its involvement in protein metabolism and cellular growth, is important to the immune system. It helps maintain the health of lymphoid organs that make your white blood cells.

Requirements:

Females:

1 to 3 years 0.5 mg per day.
4 to 8 years 0.6 mg per day.
9 to 13 years 1.0 mg per day.
14 to 30 years 1.3 mg per day.
31+ years 1.5 mg per day.

Males:

1 to 3 years 0.5 mg per day.
4 to 8 years 0.6 mg per day.
9 to 13 years 1.0 mg per day.
14 to 30 years 1.3 mg per day.
31+ years 1.7 mg per day.

Food Sources:

Good sources include meats, whole grain products, vegetables, and nuts. Cooking, storage and processing losses of vitamin B6 vary and in some foods may be more than 50%,depending on the form of vitamin present in the food. Plant foods lose the least during processing as they contain mostly pyridoxine which is far more stable than the pyridoxal or pyridoxamine found in animal foods.Excellent sources of vitamin B6 include spinach, bell peppers, and turnip greens.Very good food sources of vitamin B6 include garlic, tuna, cauliflower, mustard greens, banana, celery, cabbage, crimini mushrooms, asparagus, broccoli, kale, collard greens, Brussels sprouts, cod and chard. For example, milk can lose 30% to 70% of its vitamin B6 content when dried. Vitamin B6 is found in the germ and aleurone layer of grains and milling results to the reduction of this vitamin in white flour.
