Cytochrome P450 1

Learn the basics about how atoms bond when learning about the structure of atoms. Bonds form by the attraction of negatively charged electrons and the positive nucleus of atoms. Atoms have a positively charged tiny nucleus which contains...

Using data from NASA's Fermi Gamma-ray Space Telescope, scientists have discovered a gigantic, mysterious structure in our galaxy. This never-before-seen feature looks like a pair of bubbles extending above and below our...

In this video, the smallest particle of a chemical element, the atom, is discussed along with its various representations. The video provides information on the structure of atoms and their various components, including the nucleus,...

A great magnetic bubble surrounds the solar system as it cruises through the galaxy. The sun pumps the inside of the bubble full of solar particles that stream out to the edge until they collide with the material that fills the...

Pyruvate Carboxylase

We know that redox reactions are ones that involve electron transfer. Something is oxidized, and something else is reduced. But these reactions can be tricky to balance when surrounding water molecules are involved in the reaction. Let's...

An introduction to the Grignard reaction.

Nicotinamide Nucleotide Transhydrogenase

Methanogenesis: Intestinal Biosynthesis of Methane

This is a video that explains the electronic structure of atoms and ions and how it relates to their position on the periodic table. It covers the basics of electron shells, how to fill them, and how to represent an element's electronic...

Introducing the E1 reaction.

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...

In this video, we will learn how to write half equations for simple redox reactions. A half-equation shows what happens at one of the electrodes during electrolysis, so we need to be able to complete and balance half-equations for these...

The famous Crab Nebula supernova remnant has erupted in an enormous flare five times more powerful than any previously seen from the object. The outburst was first detected by NASA's Fermi Gamma-ray Space Telescope on April 12...
