functional proteins and structural proteins
Proteins are made up of amino acids, which are made up of amines (NH2) and carboxyls (COOH). They are joined by peptide bonds. Examples of functional categories of proteins includes Contractile proteins, regulatory proteins, structural proteins, transport proteins, catalytic proteins and immunological 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
No, it most be carefully note that all enzymes are mostly proteins and not all proteins are enzymes. Enzymes carry out the catalysis of biochemical reactions in and out of the cells. there are different non enzymatic structural and functional proteins they do have important roles such as hormones, structural proteins such as collagen etc.
Enzymes are proteins, each with a uniquely specific Biochemical Function.
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.
A hormone is an example of the globular class of proteins
Enzymes
The functional group of cysteine is a thiol group, also known as a sulfhydryl group, which consists of a sulfur atom bonded to a hydrogen atom. This thiol group is important for the formation of disulfide bonds in proteins, which play a role in the structure and function of proteins.
Storage molecules, transport molecules, and movement.
