377
377 molecules of water are removed ( produced) in which every peptide bond formed will need one molecule of water to be removed . ( for example: 4 monomers will be built up to a polymer of 4 , bonded by 3 bonds in the middle ) then there are 3 molecules of water released (always substract 1 from the original number: 378-1=377 bonds and water molecules)
