Biological processes tend to clone the molecules perfectly right down to specific left or right handed orientations. So the molecules formed from a biological process will all be identical. A process that just happens to form the molecules (eg. put a bunch of elements in a soup and heat and you can also get some proteins forming) form an even mixture of configurations.
