Protein

structure is

based on the

sequence of

amino acids.

functions
Functions
  • Transport - hemoglobin
  • Muscle Movement - actin and myosin
  • Chromosome movement - spindle fibers
  • Support – skin, bone
  • Defense – antibodies
  • Structural – hair, nails
  • Hormones – testosterone, adrenalin
  • Enzymes
hydrolysis
