Vitamin C is essential for the synthesis ofcollagen, a protein important in the formation ofconnective tissueand in wound healing. It acts as anantioxidant, protecting against damage by reactive molecules called free radicals. The vitamin also helps instimulatingtheimmune system. It has been shown ...
In the second part, the structure-function relationship of vitamin D was analyzed based on the ligand struc-ture, in particular by using systematic conformational analysis as a tool. On the basis of the conformational analysis of the vitamin D side chain and studies using conformationally ...
Structure-function relationships for vitamin D, its metabolites, and analogs are discussed with particular emphasis on the A-ring conformation. It is empha... WH Okamura,NRM Wing - 《Proceedings of the National Academy of Sciences of the United States of America》 被引量: 158发表: 1974年 Mole...
Some of the fat-soluble vitamins form part of the structure of biological membranes or assist in maintaining theintegrity(and therefore, indirectly, the function) of membranes. Some fat-soluble vitamins also may function at the genetic level by controlling the synthesis of certain enzymes. Unlike ...
