"Each protein molecule requires a minimum of 410 amino acids. All formed in left handed spirals. (Protein molecules do not have right handed spirals for some unknown reason.)"
I read somewhere that left handed molecules are more stable against ultraviolet light than right handed ones. Can anybody provide a source for that statement. I can't remember my source.

Not necessarily. It depends on the polarization of the light. In one direction left-hand predominates, in the other direction, right-handed.
We don't know if it's possible for right-hand life to exist in the universe; Our one example, Earth, is exclusively left-handed.
