Answer:
The three main types of lipids are - triglycerides, diglycerides, and steroids.
Explanation:
Lipids are organic compounds that are fatty acids or their derivatives. Lipids are insoluble in water but soluble in organic solvents (alcohol, ether). The three common lipids are triglycerides, diglycerides, and steroids.
An ester derived from glycerol and three fatty acids is a triglyceride. These are the main component of body fat in the vertebrates as well as the vegetable fat.
A Glyceride consisting of 2 fatty acid chains bonded to a glycerol molecule covalently through ester linkages is a diglyceride.
Biologically active organic compounds with four rings arranged in a specific molecular configuration are steroids.
