Use the three-letter abbreviations to name all tripeptides containing methionine, isoleucine, and lysine.

Amino acids are the building blocks of proteins, and each has a specific three-letter abbreviation. Methionine (Met), Isoleucine (Ile), and Lysine (Lys) are essential amino acids that play critical roles in protein synthesis and metabolism. Understanding these abbreviations is crucial for naming peptides accurately.

Peptides are formed by the linkage of amino acids through peptide bonds, which occur between the carboxyl group of one amino acid and the amino group of another. In the case of tripeptides, three amino acids are combined in a specific sequence, and the order of these amino acids affects the peptide's properties and function.

When naming tripeptides, the order of amino acids matters, as different sequences can lead to different peptides. For methionine, isoleucine, and lysine, the total number of unique tripeptides can be calculated using permutations, considering that the same amino acids can appear in different orders, resulting in distinct tripeptide names.
