Answers:
Protein biosynthesis uses only L-amino acids.
Explanation:
First, let's view how proteins are being formed.
In the usual protein biosynthesis on the ribosomes, only the L-amino acids is involved.
Some suggests that one can make similar protein biosynthesis with the D-amino acids, but the kind of amino acid used in protein biosynthesis was earlier determined by nature to be only L-amino acids.
It would be misleading to say D-proteins can be used to as They are not in any way involved in the normal mechanism of protein biosynthesis
