BIOMOLECULES AND ENZYMES

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 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: -Monosaccharides have carbon, hydrogen, and oxygen in a 1:2:1 ratio. Monosaccharides or simple sugars include glucose, galactose, and fructose.

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: -Carbohydrates have the highest oxygen to carbon ratio of any of the important organic molecules. Common monosaccharides include: glucose, fructose, galactose, ribose, and deoxyribose. Notice that the name of each of these sugars ends with the suffix-ose. This suffix, -ose, means full, specifically, full of oxygen.
