Detailed explanation-1: -Carbohydrates contain only carbon, hydrogen and oxygen atoms; prior to any oxidation or reduction, most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution, etc., are known as carbohydrate derivatives and may contain other elements.
Detailed explanation-2: -Carbohydrates = energy for cells. 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.
Detailed explanation-3: -Carbohydrate Definition Indeed, “carbo” means carbon, while “hydrate” means water, a combination of hydrogen and oxygen molecules. All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen.
Detailed explanation-4: -This view represents these molecules simply as “hydrated” carbon atom chains in which water molecules attach to each carbon atom, leading to the term “carbohydrates.” Although all carbohydrates contain carbon, hydrogen, and oxygen, there are some that also contain nitrogen, phosphorus, and/or sulfur.
Detailed explanation-5: -Carbohydrates (carbo-= “carbon”; hydrate = “water”) contain the elements carbon, hydrogen, and oxygen, and only those elements with a few exceptions. The ratio of carbon to hydrogen to oxygen in carbohydrate molecules is 1:2:1.
