Abstract

The review briefly addresses the mechanisms underlying micro- and macromolecular transport of proteins, fats and carbohydrates in the fish intestines. A special focus is on the differences between some mechanisms of micromolecular transport of peptides, amino acids and hexoses, as well as craniocaudal transport gradients, in fish compared to mammals. Transport proteins emerge at the earliest stages of fish ontogenesis, before the transition of fish larvae to exogenous feeding. The reasons behind the differences in the intestinal transport systems are analyzed.

鱼消化道中营养运输的特殊特征

摘要

这篇综述简要地论述了鱼肠中蛋白质，脂肪和碳水化合物的微分子和大分子运输的潜在机制。与哺乳动物相比，鱼类特别关注多肽，氨基酸和己糖的微分子转运某些机制以及颅尾骨转运梯度之间的差异。在鱼幼体向外源摄食过渡之前，转运蛋白出现在鱼类个体发育的最早阶段。分析了肠道运输系统差异的原因。
