Study Notes

Free Radicals and Antioxidants

Free radicals are unstable molecules with unpaired electrons.
Their high reactivity stems from the electron's preference for pairing.
Free radicals destabilize themselves by taking electrons from other molecules, causing damage.
Antioxidants donate electrons to free radicals without becoming unstable themselves.
This neutralizes the free radical and prevents cellular damage.

Enzymes and Substrates

Maltase breaks down maltose.
Sucrose does not work on sucrase. Sucrase breaks down sucrose.
Hydrolysis is a type of reaction, not an enzyme.
