There are a total of six different amino acid sequences for a tripeptide containing one molecule each of alanine, leucine, and glutamic acid. Using three letter abbreviations for the amino acids, draw the six possible sequences of amino acids.
Tree letter abbreviations for three listed aminoacids are: Alanine - Ala Leucine - Leu Glutamic acid - Glu. Possible sequences of aminoacids are (from N- to C-term): 1. Ala-Leu-Glu 2. Ala-Glu-Leu 3. Glu-Ala-Leu 4. Glu-Leu-Ala 5. Leu-Glu-Ala 6. Leu-Ala-Glu
