Transcript of COLLAGEN AND HAEMOGLOBIN

Collagen
A globular Protein.
Located within red blood cells
Its role is too transport oxygen around the body of animals.
Differences
Collagen has a repeating sequence of amino acids in polypeptide chains, whereas haemoglobin has no repeating sequence.
Collagen is Fibrous whereas haemoglobin is globular.
Collagen has no prosthetic group but haemoglobin has a prosthetic haem group.
Collagen has three identical polypeptide chains whereas haemoglobin has 4 chains, 2 alpha and 2 beta.
there are hydrophobic groups on the outside of collagen therefore it is insoluble; whereas haemoglobin has hydrophilic groups and is soluble .
Similarities
Both are proteins.
Both have quaternary structure.
They both contain peptide bonds in their primary structure.
Both have disulphide bridges in their tertiary structure.
COLLAGEN AND HAEMOGLOBIN
What are they?
Collagen and Haemoglobin are both proteins which show quaternary structure.
Haemoglobin
It has a prosthetic Heme group which the oxygen bonds too for trasnportation.
It can carry 4 oxygen molecules at one time.
Collagen is an important structural protein, found in connective tissue and artery walls.
It is a "fibrous" protein.
It shows quaternery structure formed of three polypeptides wound around each other, every third polypeptide is glycine creating many hydrogen bonds.
its coiled structure and many hydrogen bonds make it a strong molecule giving strength too the walls of arteries.
