Detailed explanation-2: -Carbohydrates are made of carbon (C), hydrogen (H), and oxygen (O), or CHO, in an approximate ratio of 1:2:1. All sugars are carbohydrates. Another word for sugar is saccharide.

Detailed explanation-3: -Carbohydrates are organic species having carbon, hydrogen and oxygen atoms in a ratio of 1:2:1.

Detailed explanation-4: -The ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1. The component carbon (C, carbo-) and the component water (H20, -hydrate) give the name to this group of organic molecules.

Detailed explanation-5: -Carbohydrates are organic molecules composed of carbon, hydrogen, and oxygen, usually in a ratio of 1:2:1. Carbohydrates include sugars, starch, cellulose, and glycogen. Carbohydrates are the primary sources of energy for most organisms.
