It comprises a synthesis step that introduces new pathways and genetic controls ...
Metabolism refers to all of the chemical reactions that take place within an organism by which complex molecules are broken down to produce energy and by which energy is used to build up complex molecules. An example of a metabolic reaction is the one that takes place when a person eats a ...
Chemical reaction networks that transform out-of-equilibrium ‘fuel’ to ‘waste’ are the engines that power the biomolecular machinery of the cell. Inspired by such systems, autonomous artificial molecular machinery is being developed that functions by catalysing the decomposition of chemical fuels, ...

3.2. Reaction of o-Quinones with Thiols The reactivity of thiols with o-quinone is astonishingly very fast. For example, one would expect that a nucleophile which is present internally on the quinone at a suitable position would have the greatest advantage of using proximity effect to exhibit ...
reactions can involve the breakdown of molecules as well as building molecules. The sum of all biochemical reactions (what is built and broken down) in an organism is calledmetabolism. Just like theproperties of a chemical reaction, abiochemical reactioncontains the same parts: reactants and ...

light provided by the bacteria is part of their natural metabolism,so producing the light requires no energy other than that which is needed to feed the organisms.This makes it much more environmentally friendly and sustainable than electric light,which consumes a huge amount of...
Coenzyme A (CoA) is one of the central cofactors of metabolism, yet a method for measuring its concentration in living cells is missing. Here we introduce the first biosensor for measuring CoA levels in different organelles of mammalian cells. The semisy
