Oct 04, 2013  · What Is Protein Synthesis The process of protein synthesis assembles the polypeptide molecules from amino acids. The actual composition and order of the amino acids in the polypeptide chain is encoded in genes. The genetic code is based on nucleotide triple sets called codons as each codon codes for a specific an amino acid.

Zwitterions in simple amino acid solutions. An amino acid has both a basic amine group and an acidic carboxylic acid group. There is an internal transfer of a hydrogen ion from the -COOH group to the -NH 2 group to leave an ion with both a negative charge and a positive charge.
