What are some examples of biomolecules and their functions?

 Biomolecules are organic molecules that are essential for life. Some examples of biomolecules and their functions are:

• Carbohydrates: These are molecules composed of carbon, hydrogen and oxygen atoms. They serve as a source of energy and structural material for cells. Examples of carbohydrates include glucose, starch, cellulose and glycogen.
• Proteins: These are molecules composed of amino acids linked by peptide bonds. They perform various functions such as catalyzing chemical reactions, transporting substances, providing structural support and regulating gene expression. Examples of proteins include enzymes, hormones, antibodies and hemoglobin.
• Lipids: These are molecules composed of fatty acids and glycerol. They function as energy storage, membrane components and signaling molecules. Examples of lipids include fats, oils, phospholipids and steroids.
• Nucleic acids: These are molecules composed of nucleotides linked by phosphodiester bonds. They store and transmit genetic information. Examples of nucleic acids include DNA and RNA.
