Detailed explanation-1: -A carbohydrate with three carbons is a triose, a carbohydrate with four carbons is a tetrose, and a carbohydrate with five or six carbons is known as a pentose and a hexose respectively. These monomers exist as a ring structure, which makes them more stable.

Detailed explanation-2: -Linear versus ring form of the carbohydrates Monosaccharides can exist as a linear chain or as ring-shaped molecules; in aqueous solutions, they are usually found in ring forms (Figure 3).
