WebLipid Transport, Storage, and Utilization. Once dietary lipids are digested in the gastrointestinal tract and absorbed from the small intestine, they need to be transported … Web23 de nov. de 2016 · These chylomicrons are transported to the Golgi and exocytosed from the enterocyte. Finally, the chylomicrons enter the lymphatic route and circulate throughout the body. The lipid transport pathway varies depending on the lipid class, lipid-chain length, and degree of saturation (Fig. 2 ).

WebHow do chylomicrons enter the bloodstream? …the blood are known as chylomicrons and consist largely of triglycerides; after absorption from the intestine, they pass through lymphatic channels and enter the bloodstream through the thoracic lymph duct. The other plasma lipids are derived from food or enter the plasma from tissue sites. Web21 de jul. de 2012 · Other important lipids. Apart from cholesterol, there are several other biologically important lipids (fats) in the body: Fatty acid derivatives. These can be used as an energy source and are transported in the blood bound to a protein called albumin. Triglycerides consist of three fatty acids linked to a chemical substance called glycerol.
