StructurePropertiesFunctions
Globular
  • Round/spherical
  • Can be tertiary or quaternary
  • Irregular shapes
  • Exact shape/structure determines function
  • More sensitive to pH and temp changes
  • Soluble
  • Metabolic functions
Fibrous
  • Long, narrow
  • Secondary
  • Regular shapes
  • Strong
  • More durable to pH and temp changes
  • Insoluble
  • Structural functions (making up tissues)
