This article from 2014 is fascinating: electrons with a preferred left-handed spin might be more likely to destroy right-handed organic molecules, and that could possibly explain why all Earthly life forms use left-handed amino acids. (note the weasel words “might”, “possibly”, etc).

I found this link in an also-interesting article shared by Ciro Villa about artificially creating right-handed DNA: http://www.nature.com/news/mirror-image-enzyme-copies-looking-glass-dna-1.19918
