Identify the amino acids in the tripeptide structure. Look for the characteristic side chains of amino acids in the structure provided.
Determine the order of the amino acids in the tripeptide. The sequence is typically read from the N-terminus (amino end) to the C-terminus (carboxyl end).
Assign the three-letter codes to each amino acid identified in the sequence. Common three-letter codes include Gly for Glycine, Ala for Alanine, etc.
Draw the tripeptide structure by connecting the amino acids in the identified order. Ensure that peptide bonds are formed between the carboxyl group of one amino acid and the amino group of the next.
Name the tripeptide using the three-letter codes in the order of the sequence, separated by hyphens (e.g., Gly-Ala-Ser).
