Fats are the predominant forms of a class of biological molecules called , which also includes fatty acids and steroids, among other molecules. These biomolecules readily dissolve in solvents such as hexane and chloroform. Because of their insolubility in water, fats and other biomolecules in this class are said to be. Triacylglycerols, also known as triglycerides, are a storage form of fat found in adipose tissue that consist of glycerol bound to. These fats are categorized based on the bonding of the carbon atoms in the chain. Fats that contain chains with no double bonds are classified as , whereas those that contain double bonds in the carbon chain are .

1. Lipids

2. Non-polar

3. Non-polar

4. Fatty acids

5. Saturated fats

6. Unsaturated fats

Explanation:

LIPIDS are one of the four major biomolecules in living systems. A form of lipids are fats which constitute most lipids i.e. predominant. Lipids also includes fatty acids, steroids and other molecules.

Lipid biomolecules readily dissolve in POLAR solvents such as hexane and chloroform. Because of their insolubility in water (polar solvent), fats and other biomolecules in this class are said to be NON-POLAR.

Triacylglycerols, also known as triglycerides, are forms of fat that is composed of a glycerol molecule bound to three molecules of FATTY ACIDS.

Based on the bonding of the carbon atoms in the chain, fats that contain chains with no double bonds are classified SATURATED FATS, while those that contain double bonds in the carbon chain are UNSATURATED FATS.
