All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons...

In this video Paul Andersen explains how redox reactions are driven by the movement of electrons from the substance that is oxidized to the substance that is reduced. Oxidation is the loss of electrons and reduction is the gaining of...

Any chemical reaction in which oxygen is removed from a substance.

Introduction to Reductions & Sodium Borohydride (Theory & Problems)

Here we explore the catalytic mechanism of Myeloperoxidase and subsequent formation of Hypochlorous Acid and Hypothiocyanite, two reactive oxidative species (ROS). We will also see functions of Hypochlorous Acid.<br/>

Osteoclasts Physiology and Wolff's Law

It's time to start our survey of the periodic table, and we are going to start with just one element, hydrogen. This is the most abundant element in the universe by a wide margin. What does it do? What are its properties? What are its...

Thyroid Hormones

Corrin/B12 Biochemistry: Cobalamin Adenosyltransferase

Superoxides and Superoxide Dismutase: Physiology, Biochemistry, and Inorganic Mechanism

This nugget justifies the position of Hydrogen in the modern periodic table and discusses the occurrence of isotopes of Hydrogen.

In this video, we will look at the chemistry behind the production of iron from iron ore. In early Earth history, iron, like all other metals, would have been found as an element in the crust of the planet. Later when plants evolved that...

NEW! Mammalian Cytochrome c Oxidase Mechanism

Migratory insertions are very different than the first three types of organometallic reactions we have looked at. For example, this process is only possible with ligands that are cis to one another. Let's look at how this works!

It describes electronic configuration of the elements of group 14, their physical, chemical properties and their uses.

We know about a lot of different oxidizing and reducing agents that facilitate a variety of different transformations. But we haven't touched upon the precise transformation that can be achieved by diisobutylaluminum hydride, also known...

Learn the basics about Electron exchange in oxidation-reduction reactions. What is an electron exchange? What are oxidation and reductions reactions? Find out more in this video!
