Lipids- Properties, Structure, Classification and Functions

Lipids definition Lipids are a heterogeneous group of organic compounds that are insolub­le in water and soluble in non-polar organic solvents. They naturally occur in most plants, animals, microorganisms and are used as cell membrane components, energy storage molecules, insulation, and hormones. Properties of Lipids Lipids may be either liquids or non-crystalline solids at room temperature. Pure fats and oils are colorless, odorless, and tasteless. They are energy-rich organic molecules Insoluble in water Soluble in organic solvents like alcohol, chloroform, … Read more

Membrane Lipids

Membrane Lipids

Biological membranes consist of a lipid bilayer to which proteins and carbohydrates may be associated or covalently linked. Membrane lipids are lipids involved in forming the structure of biological membranes – both the cell membrane and intracellular membranes – and in membrane function, namely compartmentalization of biological processes. Membrane lipids consist primarily of phospholipids, glycolipids, and cholesterol, which can be arranged in bilayers and organized with integral and peripheral membrane proteins to generate functioning membranes. This lipid bilayer is fluid, with individual … Read more
