Expert Solution

There are 4 major calsses of biomolecules -

1. Carbohydrate

Monomer - Monosaccharide
Contain Carbon, oxygen and hydrogen
Monosaccharide (like glucose) join to form disaccharide, polysaccharide or carbohydrate
Example - glucose (monosaccharide), starch and glycogen are polysaccharide.
Function - provide energy and structure to cell

2. Lipid

Monomer - Fatty acid and glycerol
Contain Carbon, hydrogen and oxygen
Found in oil, butter,
Function - stores energy, forms phospholipid layer (membrane of cell)

3. Protein

Monomer - Amino acid
Contain - carbon, oxygen, hydrogen and Nitrogen (may contain sulphur)
Joined by peptide bond
Function - provide structure to cell, carry out biological reaction
Example - hemoglobin, albumin

4. Nucleic acid

Monomer - Nucleotide (which is formed by pentose sugar, nitrogenous base and phosphate)
Contain - Carbon, hydrogen, oxygen, nitrogen and phosphorus
Example - DNA, RNA
Function - acts as genetic material for cell
