What is a biomolecule

What is a Biomolecule?

  • Organic molecule made by living organisms

  • Consist mostly of carbon (C), hydrogen (H), and oxygen (O)


Monomers vs polymers

Monomers vs. Polymers

  • Monomers:

    • Molecules that may react with similar molecules to form a chain

  • Polymers:

    • A chain of many monomers that are chemically bonded together


Formation of polymers

Formation of Polymers

  • Dehydration Synthesis (Condensation): Two hydrogen atoms and one oxygen atom are removed from the monomers to form water, and the two monomers are joined together.


Breakdown of polymers

Breakdown of Polymers

  • Hydrolysis—the reverse of dehydration synthesis (condensation)

  • Water added to the polymer, un-linking the chain and breaking it back down to its original monomer units


Carbohydrates

Carbohydrates

  • Group of organic molecules that includes sugars, starches and cellulose.

  • Function:

    • Energy

    • Structural Support

    • Cell Wall

    • Cell Membrane Marker


  • Monosaccharide example

    Disaccharide example

    Polysaccharide example

    Lipids

    Lipids

    • Organic molecule group including fats and phospholipids

  • Function:

    • Energy storage

    • Insulation

    • Part of cell membrane (phospholipids)

    • Hormones

    • Monomer:

      • Glycerol and fatty acids

    • Insoluble in water

    • Do not form large polymers


  • Proteins

    Proteins

    • Group of organic molecules that provides structure and facilitates chemical reactions.

  • Function:

    • Enzymes (speed rate of chemical reactions)

    • Structural components in cells

    • Mechanical functions in muscles and cytoskeleton (internal cell framework)

    • Cell signaling

    • Immune response


  • Proteins1

    Proteins

    • Structure:

      • Monomer: Amino acids

      • Amino acids connect via peptide bonds

      • Very large molecules

      • Globular or structural


    Biomolecules discussion

    DNA

    • deoxyribonucleic acid

    • is the hereditary material

    • Monomer - nucleotides
