semiquinone वाक्य

उदाहरण वाक्य

1. Pietronigro DD, McGinness JE, Koren MJ, Crippa R, Seligman ML, Demopoulos HB . Spontaneous generation of adriamycin semiquinone radicals at physiologic pH . Physiol Chem Phys . 1979; 11 ( 5 ) : 405-14.
2. ROS generated in redox cycling contributes to anticancer activity of vitamin K . NQO1 competes with enzymes that redox cycle vitamin K to formation of semiquinone and ROS . NQO1is therefore able to detoxify vitamin K3 and protect cells against oxidative stress.
3. :S-adenosyl-L-methionine + dihydroflavodoxin + [ formate C-acetyltransferase ]-glycine \ rightleftharpoons 5'- deoxyadenosine + L-methionine + flavodoxin semiquinone + [ formate C-acetyltransferase ]-glycin-2-yl radical
4. It has been argued that a water molecule ( HOH39 ) arrives at the active site and is coordinated by His207 of subunit B, Arg31 of subunit C, and Asp82 of subunit D . The semiquinone species is protonated by protons delivered from HOH39, completing the ubiquinone reduction to ubiquinol.
