WebMolecular 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". WebApr 12, 2024 · However, the effect of different molecular weights on the non-enzymatic antioxidant system and postharvest quality of anthracnose-infected papaya is still unknown. Therefore, this study evaluated the effect of different Ch molecular weights (13, 25, and 55 kDa) on anthracnose development, antioxidant capacity, and postharvest quality of papaya.
