Detailed explanation-1: -Carbohydrates are a class of chemical compounds composed of carbon, hydrogen, and oxygen in 1:2:1 ratio, respectively.
Detailed explanation-2: -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-3: -Carbohydrates contain carbon, hydrogen, and oxygen. The hydrogen and oxygen are in a 2:1 ratio, just like water. Glucose, the most famous simple sugar, has the chemical formula C6H12O6.
Detailed explanation-4: -Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term “carbohydrate” is based on its components: carbon (“carbo”) and water (“hydrate”).
