Carbohydrate is a biomolecule consisting of carbon, hydrogen, and oxygen atoms, usually with a hydrogen-oxygen atom ratio of 2:1. Carbohydrates are macronutrients, and carbohydrates are inclusive of their function and form.
Carbohydrates are vital to nutrition and are found in a wide array of natural and processed foods. Carbohydrates are present in cereals, potatoes, and foods created with wheat flour, such as bread, pizza, or pasta. Carbohydrates are essential to all living beings and are a large group of organic compounds occurring in foodstuffs and living tissues and containing sugars, starch, and cellulose.
They include hydrogen and oxygen in the same ratio as water and can typically be broken down to distribute energy in the animal body. The role of carbohydrates is to provide us with energy for our brains and bodies.
