(Phys.org) —How does consciousness work? Few questions if any could be more profound. One thing we do know about it, jokes biophysicist Luca Turin, is that it is soluble in chloroform. When you put the brain into chloroform, ...
(Phys.org)—A family of enzymes known as heme-copper oxidases (HCOs) plays a pivotal role in the reduction of oxygen into water during cellular respiration. One mystery surrounding heme-copper oxidases is why the non-heme ...
Cytochrome P450 is a well-known family of enzymes that are involved in drug metabolism. The active site contains a heme chemical structure in which an iron atom is bound to the heme cofactor within the enzyme. The oxidation ...
(Phys.org) —Using water as fuel has been a recurrent theme of science fiction since the days of Jules Verne. A recent discovery, however, may bring it one step closer to science fact by mimicking the very first steps of ...
