amino acids

A

and

B

is:

Number of cyclic tripeptides formed with 2 amino acids A and B is:

Options

A $2$
B $3$
C $5$
D $4$

Correct answer

D. $4$

Step-by-step solution

Let two amino acid be

$\begin{cases}{H}_{2}N & - & C{HR}_{1} & - & \mathop{COOH}_{( A )}\end{cases},$ \begin{cases}{H}_{2}N & - & C{HR}_{2} & - & \mathop{COOH}_{( B )}\end{cases}$$

Tripeptide are formed from three amino acids in a combination, thus 4 tripeptides can be formed from two amino acids in the following combination:

Number of cyclic tripeptides formed with 2 amino acids A and B is:
