Fig. 12.3.Chemical structure of selected natural antioxidants and vitamins. Vitamin E is absorbed in the intestine40to formchylomicronparticles. Circulation of chylomicron particles (a structure formed with fatty acids, phospholipids, cholesterol, vitamin E and other hydrophobic molecules) in plasma is ...
zanes, R2N―RN―NR―NR2. Thus, the radical 1,1-diphenyl-2-picrylhydrazyl (structure II) exists as a stable violet solid. Similar examples of free radicals, in which, however, the odd electron is onoxygen, are also known—e.g.,the 2,4,6-tri-tert-butylphenoxy radical (structure III...
V E is very helpful to human health and has been investigated widely for long time. In this paper, the type, structure, function and the antioxidation mechanism of vitamin E are summarized. Some general methods of separation, extraction and concentration of vitamin E are also introduced.关键词...
We present a theoretical study of the geometric structure of Co(corrin)(L)(R)+ (R = CH3, i-C3H7 and adenosyl and L = NH3, pyridine and 5,6-dimethylbenzimidazole) as model systems for the vitamin B12 coenzyme. We have optimized the geometries of nine corrin derivatives with axial ligan...
With the exception ofvitamin C(ascorbic acid), all of the water-soluble vitamins have a catalytic function; i.e., they act ascoenzymesof enzymes that function inenergy transferor in the metabolism of fats, carbohydrates, and proteins. The metabolic importance of the water-soluble vitamins is ...
