1. The active molecule is strychnine, a compound often used as a pesticide. 2. Activation then requires an active molecule of MT1-MMP and auto catalytic cleavage. 3. Scientists in Macao Laboratory isolated the active molecule of the plant in late 2006. 4. Purification processes were used to isolate the active molecule . 5. In general, this phenomenon will be exhibited in absorption bands of any optically active molecule . 6. PET works by introducing a radiolabeled biologically active molecule . 7. He said more studies are needed to pinpoint the active molecule among a dozen or so. 8. The stability of these microbubbles is due to elastic skins or membranes consisting of surface-active molecules . 9. Encapsulation aims at the protection and controlled release of active molecules when immersed in an environment. 10. Ibopamine can be rapidly hydrolysed to epinine which is the active molecule responsible for the mydriatic effect.
