Proteins have a variety of functions within all living organisms.

Proteins can be used for many different functions, for example:

  • Enzymes
  • Carrier proteins
  • Anti-bodies
  • Hormones

They are key with in the cell; second in quantity only to water.

The two types of protein carry tend to carry out different functions:

  • Fibrous proteins are formed like a rope, they are tightly twisted; this makes them very stable and good for structural functions (like collagen.)
  • Globular proteins form a bundle which is more suited to carrying out metabolic functions (like enzymes.)
