HUMAN NUTRITION

Detailed explanation-1: -The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose.

Detailed explanation-2: -Carbohydrates are also important structurally. In plants, the carbohydrate cellulose is an important component of the cell wall and helps provide rigid structure and support for the plant. Chitin is a type of carbohydrate used in the cell walls of fungi and the exoskeleton of arthropods and some marine animals.
