| 摘 要： | 肽以逆浓度梯度转运 ,主要依赖H + 浓度或依赖Ca2 + 浓度转运 ,肽比游离氨基酸吸收的更快 ,肽的吸收还可以避免氨基酸之间的吸收竞争。对于反刍动物 ,瘤胃和瓣胃是其肽吸收的主要位点 ,这些观点的提出使人们对新蛋白质体系的认识得到了进一步的丰富和完善

| Abstract: | Peptides are transported against a concentration gradient by a energy requiring system, the active transport driven by a H+ gradient and a Ca2+ gradient. Peptides generally are absorbed more rapidly than free amino acids and the absorption of amino acids as peptides could avoid absorption competition among different amino acids. Rumen and omasum are found to be main sites of peptide absorption in the ruminant. The current knowledge in peptide absorption will improve our understanding in protein nutrition for use of the new protein system in both ruminant and non-ruminant animals. |
