Usage

What is a carbohydrate? A carbohydrate is an organic compound that is made of hydrogen, carbon, and oxygen. Most carbohydrates have twice as much hydrogen as oxygen and carbon.In chemistry, a compound is a pure substance of two or more elements stuck together. An organic compound is a compound that contains hydrogen and carbon (hydrocarbons).Carbohydrates are extremely important to life and neither plants nor animals would be able to survive without them. Fortunately, carbohydrates are abundant in nature.Both the cell walls of plants and the tissues of animals are made partly out of carbohydrates. Additionally, both plants and animals use carbohydrates to produce and store energy. Without carbohydrates, neither plant nor animal cells could function and both would quickly die.Carbohydrates come from green plants as a product of the process known as photosynthesis in which plants combine carbon dioxide and water. Typically, animals get their carbohydrates by eating the plants, eating the fruits and vegetables of the plant, or eating other animals.It is very common in nutritional discussions to shorten carbohydrates to carbs.
