WebbMolecular mass or molar mass are used in stoichiometry calculations in chemistry. In related terms, another unit of mass often used is Dalton (Da) or unified atomic mass unit (u) when describing atomic masses and molecular masses. It is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu". WebbNisin is a polypeptide (molecular weight 3500) that usually exists as a dimer. It is produced by Lactococcus lactis and may be formed naturally in cheese. The polypeptide chain … lms faculty app
