The Chemical and Physiological Relationship between Vitamins and Amino Acids

摘要: Publisher Summary The importance of amino acids as the building stones proteins which protoplasm is largely composed generally realized. It perhaps not so realized that their functions in animal metabolism extend far beyond this structural function. Some tissue proteins, either by conjugation with an active prosthetic group or some slight modification structure, assume rate enzymes catalyze many digestive and metabolic reactions. Many protein derivatives, acid derivatives are to be found among hormones, important class products concerned regulation proper use food. In immunity, resistance disease, chemical defense against invasion body alien substances, specific possess very functions. These antibodies appear merely modifications serum globulin. Amino such creatine, carnosine, glutathione, ergothioneine, serve various tissues body, while bile acids, originating part from cystine glycine, perform duties digestion fats absorption nutrients soluble fat solvents. This chapter discusses somewhat fragmentary often inconclusive evidence has been revealed concerning existence nature physiological relationships vitamins on one hand, functional combinations other.
