| 释义 | macromolecule (once / 1181932 pages) n WORD FAMILY macromolecule: macromolecular, macromolecules USAGE EXAMPLESAccording to one such hypothesis, in normal ageing, macromolecules become oxidized and can no longer be degraded by lysosomes4. Nature(Nov 08, 2016) The presence of such macromolecules is exciting to researchers, as they are the essential ingredients of life. New York Times(Sep 14, 2016) I retained a slight hope that I might profit from the meeting on the structures of biological macromolecules. James D. Watson, Double Helix(1968) n any very large complex molecule; found only in plants and animals Syn|Hypo|Hyper supermolecule protein any of a large group of nitrogenous organic compounds that are essential constituents of living cells;
