"Lipids are a broad group of organic compounds which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others."
Learning about the structure and function of lipids, including fatty acids, triglycerides, and phospholipids.
Introduction to Lipids: Basic concepts of lipids, their classification and properties.
Fatty Acids: Structure, nomenclature, properties, and use in lipid biosynthesis.
Glycerolipids: Structure and properties of glycerol-based lipids, including triacylglycerols, phospholipids and sphingolipids.
Sterols: Structure and properties of sterols, including cholesterol and steroid hormones.
Lipid Biosynthesis: Synthesis of lipids in cells, including fatty acid metabolism, glycerolipid synthesis, and sterol biosynthesis.
Lipid Metabolism: The catabolism of lipids and their role in energy metabolism, including beta-oxidation, ketone body formation, and lipoprotein metabolism.
Lipid Function: Roles of lipids in cell membranes, as hormones, as signaling molecules, and in energy storage.
Lipid Analysis: Methods for lipid extraction, separation and identification, including TLC, GC and MS.
Biochemistry and Biophysics of Lipid Membranes: Structural and functional properties of lipid bilayers, lipid-protein interactions, and methods for studying lipid membranes.
Lipid Disorders: Clinical lipid disorders, including hyperlipidemia, atherosclerosis, and lipodystrophy.
Fatty acids: These are the basic units of lipids and are long-chain hydrocarbons with a carboxyl group at one end. They can be either saturated or unsaturated.
Triglycerides: These are the primary storage form of lipids in animals and plants. They consist of three fatty acids attached to a glycerol backbone.
Phospholipids: These are the structural components of cell membranes. They consist of two fatty acids, a polar head group, and a glycerol backbone.
Sphingolipids: These are structural components of cell membranes and play a role in signal transduction. They consist of a sphingosine backbone, a fatty acid, and a polar head group.
Sterols: These are lipids that serve as hormones or as structural components in cell membranes. Cholesterol is the most well-known sterol.
Glycolipids: These are lipids that have a sugar molecule attached to them. They play a role in cell recognition and signaling.
Waxes: These are long-chain fatty acids combined with long-chain alcohols. They provide a waterproof coating for many plants and animals.
Eicosanoids: These are signaling molecules that play a role in inflammation, blood clotting, and other physiological processes. They are derived from arachidonic acid.
Terpenes: These are lipids that consist of repeating units of isoprene. They play a role in plant defense mechanisms and are used in the production of essential oils.
Polyketides: These are complex lipids that are synthesized by bacteria and fungi. They have a wide range of biological activities, including antibiotic and anti-cancer properties.
"The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes."
"Lipids have applications in the cosmetic and food industries, and in nanotechnology."
"The amphiphilic nature of some lipids allows them to form structures such as vesicles, multilamellar/unilamellar liposomes, or membranes in an aqueous environment."
"Biological lipids originate entirely or in part from two distinct types of biochemical subunits or 'building-blocks': ketoacyl and isoprene groups."
"Using this approach, lipids may be divided into eight categories: fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides (derived from condensation of ketoacyl subunits); and sterol lipids and prenol lipids (derived from condensation of isoprene subunits)."
"Although the term 'lipid' is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides."
"Lipids also encompass molecules such as fatty acids and their derivatives (including tri-, di-, monoglycerides, and phospholipids), as well as other sterol-containing metabolites such as cholesterol."
"Some essential lipids cannot be made this way and must be obtained from the diet."
