Chemical Society at Buffalo, September, 1931.At that time we noted that the concentrates examined had absorption maxima at 2600 A., but as the concentrates were admittedly impure, and as some also presented maxima at other wave-lengths, we hesitated to identify any band with vitamin B.FRANCIS...
Chemical Structure Of Vitamin B6 Functions and deficiencies: Pyridoxine is normally stored as pyridoxal-5-phosphate (PLP), the coenzyme form of the vitamin. It is needed for metabolism of amino acids, cellular metabolism of carbohydrate, protein and fat formation of neurotransmitters and production ...
THE experiments of Heyroth and Loofbourow have established a close correlation between the physiological activity of concentrates of vitamin B(after eliminating inactive purines and pyrimidines, which absorb in the same spectral region), and the intensity of the absorption band at 2600 A. They ...

Since the "mad cow" incident in European, the use of the chemical structure of vitamins and other nutritional supplements to replace the clear "MBM" has more room for development. Currently the world's production of VB12 is mostly used for the feed industry. 3. In other aspects of the ...
摘要: The chemical structure, biopotency and physicochemical properties of vitamin E (and related compounds) are discussed, including its occurrence and stability in food. Also, discussions on the intestinal absorption, transport and metabolism of vitamin E are presented.关键词:...
