Measure of molecular weight or mass. One hydrogen atom has mass of 1 Da, so 1 Da = 1 g/mol. Proteins and other macromolecule molecular weights are usually measured in kDa or kD (kilodaltons) – 1000 Da. Average amino acid = 110 Da….

metabolic labelling

The process in which bacterial cells are grown in the presence of radiolabelled precursors of macromolecule synthesis (DNA, protein, fatty acids and peptidoglycan). Blocks to radiolabel incorporation can identify a mutant defect or the cellular target of an antimicrobial compound….
