The molecular mass will be 3*150 - 2*18 = 414 g/mol
Because 1 water is lost by the formation of a peptide bond, and there are 2 peptide bonds between the three amino acids.
Because 1 water is lost by the formation of a peptide bond, and there are 2 peptide bonds between the three amino acids.
Tripeptide is made of 3 amino acids, which has 2 peptide bonds.
2 water molecules are released, to form peptide bond which weighs 18(18 x 2) daltons.
=(150x3)-36= 414 daltons.

A tripeptide is made of three amino acids that are linked by a peptide bond. In this peptide bond a water molecule is released, which weighs 18 daltons. As there are two peptide bonds formed in this case, two molecules of water would be lost i.e. 36. So the answer would be (150x3)-36= 432 daltons.
