Carbohydrates are the same thing as sugars. A single glucose molecule is an example of a monomer A single unit of a glucose molecule is referred to as a polysaccharide Carbohydrates store energy in their bonds. Carbohydrates provide structural support for cells in the form of cellulose
Nucleotides
It is an organic molecule made up of three basic components- a nitrogenous base, phosphate,and pentose sugar. The nucleotides are important for metabolic reactions andthe formation of DNA (deoxyribonucleic acid) and RNA (ribonucleic acid).
Nucleic Acids
Nucleic acids are essential biomolecules present in prokaryotic and eukaryotic cells and viruses. They carry the genetic information for the synthesis of proteins and cellular replication. The nucleic acids are of two types: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The structure of all proteins and ultimately every biomolecule and cellular component is a product of information encoded in the sequence of nucleic acids. Parts of a DNA molecule containing the information needed to synthesize a protein or an RNA are genes. Nucleic acids can store and transmit genetic information from one generation to the next, fundamental to any life form.

Introduction
The substances in food known as nutrients give us the energy needed for development, repair, and other vital living activities. Although not all nutrients are energy-producing, they are all required in one way or another. There are two groups of these nutrients:
- macronutrients, which the body needs in huge quantities.
- micronutrients, which the body needs in minute amounts.
There are some nutrients that the body is unable to produce on its own and must be obtained from the diet. These are essential for the body. Fats, protein, carbs, iron, and other nutrients are among the most vital.
