Presentation Transcript

Examples
Examples

Enzymes (amylase)

Hemoglobin

Insulin

Keratin


Monomers amino acids aa
Monomers = Amino Acids (aa)

  • Structure:

  • amino group

  • carboxyl group (acid)

  • R group (side chain) - determines the aa (20 essential to life)


Polymer protein polypeptide
Polymer = Protein (Polypeptide)


Protein

structure is

based on the

sequence of

amino acids.


Functions
Functions

  • Transport - hemoglobin

  • Muscle Movement - actin and myosin

  • Defense – antibodies

  • Structural – hair, nails

  • Hormones – testosterone, adrenalin

  • Enzymes


Hydrolysis
Hydrolysis

  • Adding H20 to break a covalent bond

  • Splits polymers into monomers
