BIBC 120 Lecture Notes - Lecture 9: Reverse Cholesterol Transport, Lipoprotein Lipase, Very Low-Density Lipoprotein
Document Summary
The chylomicron remnant is transported to the liver, to be packaged as vldl (different composition, very low-density lipoproteins: vldl is stripped of fatty acids through lipoprotein lipase. Vldl -> ldl: ldl: major delivery source of cholesterol. Functions of proteins: form enzymes and many hormones. Immune functions (ab: building blocks of cellular structures, maintain fluid balance, source of n and essential amino acids (eaa, energy yielding, gluconeogenesis. In the stomach: has enzyme pepsin and hcl to partially digest protein. In the pancreas: releases enzymes into small intestine to further digest protein. In the small intestine: final digestion of protein to aas, dipeptides, and tripeptides occurs: liver: aas absorbed into the portal vein and transported to the liver. From there they enter the general bloodstream: large intestine: little dietary protein is present in feces. Dietary protein deficiency: edema, proteins in capillaries are big, so stuck in blood vessels and provide osmotic pressure that maintains blood pressure.
