A tripeptide is formed by linking three amino acids together. Since there are 20 common amino acids, and each position in the tripeptide can be occupied by any of the 20 amino acids, the total number of different tripeptides that can be made is 20^3 = 8,000, which is represented as 8.0 × 10^3 in scientific notation.
