lipid metabolism

Cards (47)

  • The liver is the primary site of fatty acid synthesis.
  • Lipid metabolism is the synthesis and degradation of lipids in cells.
  • Lipid metabolism is also involved in the breakdown and storage of fats for energy.
  • The fats obtained from food and synthesized by the liver.
  • Lipogenesis is the process of synthesizing these fats.
  • Triglycerides and cholesterol are the major lipids found in the human body.
  • Fatty acids and membrane lipids are other types of lipids found in the body.
  • Triglycerides are an ester derived from glycerol and three fatty acids.
  • The first step in lipid metabolism is digestion.
  • Lipid metabolism is a synthesis of structural and functional lipids for cell membranes.
  • Consumed dietary fats and stored fat are two sources of energy.
  • Lipid metabolism often starts with hydrolysis in the digestive system.
  • Various enzymes assist in hydrolysis.
  • Lipid digestion is the breakdown of lipids.
  • Lipid absorption is controlled by the pancreas and small intestine.
  • Lipid absorption is where fatty acids absorbed into intestinal wall.
  • Lipid transportation is where fatty acids are packaged and transported.
  • Lipid storage is where the accumulation of fats.
  • Lipid catabolism is where beta oxidation in mitochondria and peroxisomes happens.
  • Lipase plays a crucial role in lipid digestion.
  • The first step involves breaking triglycerides into monoglycerides.
  • The detailed breakdown includes the use of 7 FAD, 7 NAD+, 7 CoASH, 7 H2O, and the given substrate, which results in the production of 8 CH3CO-SCoA, 7 FADH2, 7 NADH, and 7 H+. This process represents the catabolism of fatty acids into acetyl-CoA.
  • Adipose tissue stores provide energy alongside dietary fats.
  • Synthesis of triacylglycerols, lipid membranes, and cholesterol is achievable by organisms.
  • Diverse pathways contribute to the biosynthesis of these lipids.
  • Chylomicrons travel through tissues.
  • .Lipoprotein lipase breaks down chylomicrons.
  • Triglycerides break down into fatty acids and glycerol.
  • Fatty acids and glycerol enter cells for energy
  • Unutilized cholesterol returns to the liver through the bloodstream.
  • Triglycerides are the primary storage form in white adipose tissue.
  • Lean young adults store approximately 10–20 kilograms of triglycerides.
  • Lipid storage involves activation of free fatty acids, esterification, and droplet formation
  • Lipoprotein lipase is essential in the lipid storage.
  • Very-Low-Density Lipoproteins (VLDL):Transport triglycerides synthesized by the body
  • Low-Density Lipoproteins (LDL):Transport cholesterol to peripheral tissues.
  • Lipoproteins facilitate transport due to the hydrophobic nature of lipids
  • Amphipathic structure of lipoproteins enables blood transport.
  • Chylomicrons specifically transport lipids from the small intestine.
  • Different lipoproteins have varying densities based on the fats they carry.
