Which are the three main types of lipids

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.

Triglycerides, diglycerides, and steroids.

Explanation:

Lipids may be defined as the organic compounds that contain fatty acids and their derivatives. Lipids are generally insoluble in water but easily dissolve in the organic solvents.

The three common lipids are triglycerides, diglycerides, and steroids. Ester can be derived by the reaction between the glycerol and three fatty acids known as triglyceride. Glyceride that consists of 2 fatty acid chains liked with a glycerol molecule by the ester bond is known as diglyceride. Steroids are the biologically active compounds that contain four rings in its structure arranged in the fixed configuration.

Thus, the correct answer is triglycerides, diglycerides, and steroids.
