What type of macronutrient is primarily made of simple sugars?

Carbohydrates are the macronutrients primarily made of simple sugars. Simple sugars, or monosaccharides, include glucose, fructose, and galactose. When these simple sugars combine, they can form disaccharides like sucrose (table sugar) and lactose, as well as polysaccharides such as starch and glycogen, which serve as energy storage.

The primary function of carbohydrates in the diet is to provide energy, making them essential for cellular metabolism. They are the preferred source of energy for the brain and muscles during physical activity. Understanding the composition of carbohydrates as being largely made up of simple sugars is crucial for recognizing their role in nutrition and overall health.
