Question

There are a total of six different amino acid sequences for a tripeptide containing one molecule

each of serine, valine, and glycine. Using three-letter abbreviations for the amino acids, draw the

six possible sequences of amino acids.

Answer 1

Tree letter abbreviations for three listed amino acids are:

Alanine - Ala

Leucine - Leu

Glutamic acid - Glu.

Possible sequences of amino acids 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
