Lipids are organic compounds that are fatty acids or their derivatives and are insoluble in water but soluble in organic solvents. They include many natural oils, waxes, and steroids.
Imagine lipids like tiny floating buoys on water. Just like buoys float on water because they're less dense than water itself, lipids don't mix with water due to their hydrophobic nature.
Triglycerides: An ester derived from glycerol and three fatty acids. They are the main constituents of body fat in humans and other animals.
Phospholipids: A class of lipids that are a major component of all cell membranes as they can form lipid bilayers.
Steroids: A type of lipid characterized by a carbon skeleton with four fused rings, commonly found in hormones, body cells, and some vitamins.
