Fortschrittsbericht Die intestinale Phase der Peptidabsorption

摘要: Peptides and not amino acids are the prevailing degradation products of protein digestion which formed in intestinal lumen absorbed from mucosa. These two families differ absorption. The differences become manifest when absorption peptide mixtures is compared with that equimolecular free acids. peptides occurs different ways: 1. Transport intact through membrane into mucosal cell subsequent hydrolysis by intracellular hydrolases. 2. Hydrolysis hydrolases localized on luminal side transport thus membrane. mechanisms do exclude each other. way energy supplied for yet elucidated. nutritive importance only case dipeptides tripeptides. It enables particular introduction cannot be cleft membrane-bound released long-chain peptides. difference absorbing behaviour between at discussed.
