naturally occuring polymers

• Naturally occuring monomers:

  • polypeptides - long chain of amino acids
  • DNA - long chain of nucleotides
  • Carbohydrates - polyaccharides + monosaccharides in a long chain eg cellulose , starch , glycogen
• Amino acid structure:

  A) Amino group

  B) Carboxylic acid group

  
• How amino acids join to form polymers

  A) OH

  B) H

  C) Water

  
• Biological polymers:

  1. DNA
  2. Proteins
  3. Starch
  4. cellulose
• Amino acids are molecules which have at least two functional groups. All amino acids contain the NH2 group and also the carboxylic acid group COOH
• Amino acid.
