Conformations

~To be inflexible or flexible - your molecules make the difference!~
Good grief, this is what Secondary Two students will learn in time to come; you see, when your muscles contract, it is an action that is due to the cumulative rotatory motions of individual sigma bonds! Because many carbon-carbon single bonds are undergoing rotation, such conformational changes in a muscle protein causes mysoin to move its tail 60 angstroms along its adjacent actin protein chain in a step called the power stroke, and this repetitive occurrence of the power stroke then drives the movment of muscle!
As disgusting as I think this kind of hardcore medicine-type memory work is, but really, what precision! Sixty angstroms! Plus the quantum mechanical calculations that can be done on each single rotation!
I think our body's pretty cool.
~Just that it's dying everyday.~
