Q. If the molecular mass of an amino acid is 150 daltons, the molecular mass of a tripeptide will be

Solution:

Tripeptide is formed by the condensation of three amino acids with the loss of two water molecules. The molecular mass of two water molecules is 18x2=36. Therefore, tripeptide mass will be (150x3)-36=414.
