BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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-2: -Carbohydrates are a class of chemical compounds composed of carbon, hydrogen, and oxygen in 1:2:1 ratio, respectively.

Detailed explanation-3: -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-4: -Carbohydrates are hydrocarbons which are polyhydroxy aldehydes and ketones having C: H: O ratio as 1:2:1, as in glucose which has molecular formula C6H12O6. All carbohydrates, however, do not show this ratio, for example, rhamnose is a crystalline sugar, C6H12O5.

Detailed explanation-5: -The three elements namely carbon, hydrogen, and oxygen present in carbohydrates are in the ratio of 1:2:1 respectively, this is why they are called carbohydrates. In lipids, the components are the same but the ratio is less for oxygen, so it is 1:2: less than one for C:H:O.
