Structure, transport, enzymes
There are four subunits, each containing 2 a - helices and 2 b - sheets. An atom of iron is found in the center of each.
Primary - the sequence of amino acids in the protein chain
Secondary - the formation of a - helices or b - sheets from the protein chain
Tertiary - the folding of protein chains into more compact structures
Quatrenary structure - the interactions of polypeptide chains in the protein
The binding of the first oxygen makes it easier for the other oxygens to bind.
The protein may not function normally. Sickle Cell Anemia
Enough triplets (DNA bases) to code for the synthesis of a polypeptide chain (protein)
Transfer and messenger.
A genetic disease may result - hemophilia, cystic fibrosis, Tay-Sachs Disease
