Helices

... in water so they would not bond. By the way, I'm not sure if you have the entire molecule in your diagram. It is made up of 4 different alpha helices. At any rate it is vastly oversimplified and does not show the secondary or quaternary structure of hemoglobin. Yes sorry about that but it ...

... S, the last 4 having alot of valency. By the way, I'm not sure if you have the entire molecule in your diagram. It is made up of 4 different alpha helices. At any rate it is vastly oversimplified and does not show the secondary or quaternary structure of hemoglobin.

I can think it's probably by the direction of flagellar spin. Bacteria move by 'spinning' their flagella and thus the arrangement of flagellin helices which construct flagella is in certain direction (either right spin or left spin). So, I can say that if the forward movement of bacteria is caused ...

There's two types of helices(think screws). One is left handed and one is right. Also, compare DNA vs RNA.

... things like ORD-CD (tells you something about the relative amount of helix vs strands), spectroscopy (noes from nmr tells you something about helices and strands), centrifugation (tells you something about the overall shape). You can always attempt to crystallize a protein and determine its ...
