How did the chemicals for life come together??..

And there are more than 20 different amino acids, L and D are only a fraction of the amino acids in life forms.

What, exactly, did you mean by this, Void? I mean, I know there are more than 20 different amino acids. But what do you mean by "L and D are only a fraction of the amino acids in life forms"?

To the best of my knowledge theVOID is referring to the different enantiomers of amino acids due to their chiral centre (Excluding Glycine), D for a molecule that rotates plane polarised light to the right, and L to the left using Glyceraldehyde as a reference molecule. I could be completely mistaken and be taking a bias due to my favouritism of Chemistry.
