> we do not have the digestive tract of herbivores to synthesize proteins [...] The goal of the digestion is not to synthesize proteins.

Here is the DNA codon table that gives the DNA <-> amino acid translation: https://en.wikipedia.org/wiki/DNA_codon_table https://en.wikipedia.org/wiki/DNA_codon_table
