Last Updated: March 5, 2024 Introduction to Cholesterol Metabolism Cholesterol is an extremely important biological molecule that has roles in membrane structure as well as being a precursor for the synthesis of the steroid hormones, the bile...
Lipid Metabolism
The Lipid Metabolism section contains posts/pages on the basic biochemistry of biological lipids, the biosynthesis and catabolism of fatty acids, the synthesis of triglycerides, the synthesis of cholesterol, the synthesis and metabolism of the lipoproteins, the synthesis of bile acids, the synthesis of complex bioactive lipids such as the various eicosanoids, the clinically relevant omega-3 and omega-6 polyunsaturated fatty acids (PUFA), and diseases that result from defects in the various pathways of lipid synthesis and catabolism. Additional posts/pages included in this section cover metabolism of the endocannabinoids and the metabolism of ethanol (alcohol).
Lipolysis and the Oxidation of Fatty Acids
Biochemistry Topics, Lipid Metabolism
Last Updated: April 24, 2024 Lipid Digestion Utilization of dietary lipids requires that they first be absorbed through the intestine. As these molecules are oils they would essentially be insoluble in the aqueous intestinal environment. Solubilization...
