Question

What are biomolecules?

Answer 1

Biomolecules

• Biomolecules are the important organic compounds, required for the growth and maintenance of living beings.
• The range of biomolecules is from small molecules to massive macromolecules like proteins, nucleic acids, carbohydrates, lipids, and so on.

Types of biomolecules

Carbohydrates

• Plants are the primary producers of carbohydrates, that comprise a vast category of naturally occurring chemical compounds.
• Carbohydrates can be described chemically as optically active polyhydroxy aldehydes or ketones, or substances that yield such units upon hydrolysis.
• Examples of carbohydrates are glucose, starch, and cane sugar.

Lipids

• Lipids are organic compounds that are soluble in organic solvents but insoluble in water.

Nucleic acids

• Nucleic acids are chemical substances that occur naturally and act as the primary information-carrying molecules in organisms.
• Examples of nucleic acid are deoxyribonucleic acid (DNA), and ribonucleic acid (RNA).

Proteins

• Proteins are polymers of $\mathrm{\alpha }$-amino acids that are linked together by a peptide bond or peptide linkage.
• Milk, cheese, grains, peanuts, fish, and meat are excellent sources of protein.
