    Please help regarding d) part (ii), regarding the Mr of the polypeptide S.

    My way is (3*75) + (89*2) + (165*2) = 733. However the correct answer 625, but i don't get why and how. Please someone explain the concept and how to get to the actual answer.

    here buddy, I specifically made an account to answer your question

    notice in the equation the H2O molecules are missing - the ones that are supposed to be produced when the polypeptide is made (as it is a condensation reaction)

    6 H2O molecules are produced - the Mr of 1 is 18- so 18*6 = 108

    733-108=625

    welcome, you are
