Question

Solubilization of dietary lipids, achieved by mixing bile salts and degrading them with pancreatic lipases, is required for transport across the intestine where the free fatty acid and the lysophospholipid can then be resynthesized into triacylglycerols in the intestinal mucosal cells. Why is this necessary?

Describe how and why the above differs from the transport of fatty acids into the mitochondria?

Answer 1

Ashler * No transport is present in Epithelial (intestinal Epithelial cells for direct absaation of dietary lipids. So, lipids must be degraded in MAG (Moro acylglycesol]. * Through diffusion fatty acids ase will entes - into the lumen. * As diffusion occurs from High Concentrato gradient to low Concentration gradient so MAG Should be less in Epithelial cell and high in lumen. * To incintain this condition when MAG Enter's into Epethelial cells it transfered to Smooth ER [Endoplasmic aeticulum]. Then this MAG conceals into triacyl glyceso! [falty acid +MAG] . Then tohigly furiacylglyceso, phaspholipids, Vitamins and Cholestrols are packed in Vesicles in the form of "Apolipopsatein" and it will moved lia" Golgi body's

& mitochandaia - fattyacids into the the transport of fatty acids into the mi is differ. The inneamen haare of Mitochanderiais impesmiable to fatty acids. It transport Specia lized Carries System from celosol to mito Chandaice. the acyl.co.A transfered into the mitochandoial Matrix. * fatty acid oxidation is an important Source of Energy pis ATP production in Mitochondria.
