A large ribosomal subunit bonds to the initiation complex. The codon adjacent to the initiation codon bonds to its complementary anticodon, which is part of a free tRNA. The two amino acids still attached to their tRNAs align. With the help of rRNA, amino acids form peptide bonds. Then, the first tRNA is released.
Peptides are polymers of amino acids. A tripeptide contains three amino acid residues. Peptide bonds are ester linkages. Peptide bonds form from nucleophilic attack by an alpha-carboxyl carbon atom on an electron pair of an alpha-amino nitrogen atom of another amino acid.
