Question

How many tripeptides can be synthesized using just three different species of $\mathbf{\alpha }\mathbf{\text{-amino}}$acids?

Short answer

Here, 27 tripeptides can be synthesized using just three different species of alpha-amino acids.

Step-by-step solution

Tripeptides

Peptides are the straight chain of amino acids. Tripeptides are the peptides formed by connecting three amino acids in a straight chain.

Step 2: Calculation of the number of tripeptides formed

The number of tripeptides that can be synthesized using three different species of alpha-amino acids can be calculated as;

$3^3=27$

Thus, 27 amino acids can be synthesized using three different alpha-amino acid species.
