Enzyme Helpers: Metals, Vitamins, and More
Description
Enzyme helpers are needed for many enzymes to work properly. These helpers fall into two groups: cofactors and coenzymes. Cofactors are metallic ions, while coenzymes are non-protein organic molecules. Both can be tightly bound to an enzyme or attach only when the substrate binds.
Cofactors are c...

- [Narratore] In molti casi, gli enzimi hanno bisogno
di altre molecole, chiamate cofattori, per funzionare.
Queste molecole ausiliari posso essere classificate
come ioni metallici
o molecole organiche non proteiche.
Per esempio, durante la prima fase della glicolisi,
il cofattore magnesio si lega...
