control the rate of reactions and regulate cell processes. forms bones and muscles. transport substances in/out of cells or to help fight disease.
The 'Big Three' are: i) Structural; ii) Functional; and iii) Regulatory. There most certainly are many others!
functional proteins and structural proteins
Structural Proteins form Structures, like bones and muscle. Functional Proteins are you used to do stuff, so pretty much everything else
Growth and Repair
Proteins are composed of amino acids, which are the building blocks of proteins. Amino acids are linked together through peptide bonds to form polypeptide chains, which then fold into complex three-dimensional structures to create functional proteins.
Enzymes are proteins, each with a uniquely specific Biochemical Function.
Constantly and prodigeously Cell proteins are formed into at least three types of products which are i) structural eg. collagen; ii) functional such as enzymes and iii) regulatory hormones like insulin.
Proteins are nitrogenous compounds being made up of carbon, hydrogen, oxygen and nitrogen. Proteins also contain sulphur. In living systems proteins play an important role in the structural organisation eg., cell membrane, hairs, nails and muscles. Many of the proteins serve as enzymes. They are named as functional proteins.
Enzymes
A hormone is an example of the globular class of proteins
Storage molecules, transport molecules, and movement.
