Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
All carbohydrates are:
A
made of amino acids
B
composed of carbon, hydrogen and oxygen atoms
C
made of fatty acids
D
composed of carbon, hydrogen, oxygen and nitrogen atoms
Explanation: 

Detailed explanation-1: -Carbohydrates are composed of carbon, hydrogen, and oxygen and have a general formula that approximates CH2O. They are polyhydroxy aldehydes or ketones or form polyhydroxy aldehydes or ketones when hydrolyzed. Carbohydrates occur as monosaccharides, disaccharides, oligosaccharides, and polysaccharides.

Detailed explanation-2: -All carbohydrates, including sugar, therefore contain the same three elements: carbon, hydrogen and oxygen. Different arrangements of these elements form single units to make different types of carbohydrates. Glucose, for instance, is a single-unit carb with six carbon atoms, 12 hydrogen atoms and six oxygen atoms.

Detailed explanation-3: -Carbohydrates, which are made up of carbon, hydrogen, and oxygen, are organic compounds that serve as a source of energy for animals and humans [1]. The main monosaccharide is glucose, which is utilized as an energy source by animals.

Detailed explanation-4: -Basically, they are hydrated carbons. The word “carbo” means carbon and “hydrate” means water. Glucose, the most abundant carbohydrate in the human body, has six carbon atoms, twelve hydrogen atoms, and six oxygen atoms. The chemical formula for glucose is written as C6H12O6.
