Proteins

• Biological molecules 


  Monomers are molecules bonded together to form a polymer
• Monomers and polymers 


  Amino acids are monomers that form polymers callled proteins

  Carbohydrates e.g. starch are polymers made from monomers called sugars e.g glucose
• Lipids

  • there macromolecules
  • Formed from fatty acids
  • They store energy
• Enzymes

  A type of protein that speeds up chemical reaction

  enzynes break down polymers down to monomers
• Factors affecting enzymes
