HUMAN NUTRITION

Detailed explanation-1: -Sugars are made up of carbon, oxygen, and hydrogen; no nitrogen, except for amino sugars.

Detailed explanation-2: -Nitrogen is not present in fats and carbohydrates. Fats and carbohydrates contain carbon, hydrogen and oxygen atoms. Proteins contain nitrogen and smaller amounts of carbon and hydrogen atoms.

Detailed explanation-3: -The saccharides are divided into four chemical groups: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides and disaccharides, the smallest (lower molecular weight) carbohydrates, are commonly referred to as sugars.

Detailed explanation-4: -Carbohydrates (also called saccharides) are molecular compounds made from just three elements: carbon, hydrogen and oxygen. Monosaccharides (e.g. glucose) and disaccharides (e.g. sucrose) are relatively small molecules.
