Protein and Haemoglobin Structure (Biochemistry) Flashcards
What is haemoglobin?
protein found in erythrocytes
a pigment that looks red
carriers oxygen around the body which is used for respiration
= respiratory pigment
What is the structure of haemoglobin?
Quaternary, like all proteins is made of chains of amino acids
Where is haemoglobin (and all proteins made)?
On the ribosomes of the rough endoplasmic reticulum
How many polypeptide chains is Haemoglobin made up of?
4, in a very precise pattern
What primary structure polypeptide chains does haemoglobin consist of?
two a-chains
two B-chains
How many amino acids is each polypeptide chain made out of?
141
What is the haem group (haemoglobin)?
Iron Ion
What type of protein is a haemoglobin molecule?
globular protein
and prosthetic protein as it has a non-protein haem group
