HUMAN NUTRITION

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: -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-3: -Monosaccharides. The most common carbohydrates are sugars, which typically have a simple ring-like structure with 5, 6, or 7 carbons. They’re composed of hydrogen, carbon, and oxygen, and these molecules contain lots of energy.

Detailed explanation-4: -A) Carbon, hydrogen and oxygen all have protons, neutrons, and electrons (with the exception of hydrogen, which only has one proton and one electron).
