In this video, we explore normal physiology of lipoprotein metabolism and the various medications that act at this pathway.

Hemoglobin Function Bohr Effect (Macroscopic Interpretation)

GABA Biosynthesis and Catabolism

Researchers at the University of Cambridge believe a molecule present in rats could help fight obesity in humans.

The Cassini-Huygens mission arrived at Saturn in 2004, beginning an epic thirteen-year tour of the ringed planet and its many moons. Cassini and its companion probe, Huygens, were an international collaboration between NASA and...

Mars's thick early atmosphere was likely lost to space, and the Sun is a potential culprit. When high-energy solar photons strike the upper Martian atmosphere they can ionize gas molecules, causing the atmosphere to erode over time....

NADH Dehydrogenase

Learning how to assign absolute configuration (R/S) to any stereocenter.

DNA is the Swiss army knife of biological molecules, acting as both a blueprint and a building block. This animated series of short videos acts as a video glossary to define specific scientific terms or concepts in a fun, easy to...

PUFAs: Eicosanoid Biosynthesis

Chlorophyll Catabolism and Pheophytin Synthesis

We've seen that KMnO4 can oxidize alcohols and aldehydes to give carboxylic acids and ketones, but this reagent can also oxidize alkenes. The product(s) will be different depending on whether we use cold basic conditions or hot acidic...

In this video, we will explore the source of the major cause of the smell of flatulence. Intestinal sulfate-reducing bacteria reduce sulfate to hydrogen sulfide (H2S). We will see the biochemical pathway here and how it is coupled to...

Microbiology: Phenylalanine Deaminase Test

Exercise Physiology | Respiratory Quotient (RQ): What is it?

Heme Catabolism to Urobilin and Stercobilin

Defining meso compounds, inversion centers, and diastereomers.

This video is a tutorial on addition polymerization, the process of joining monomers together to form polymers. It explains the use of functional groups and double bonds in alkenes to create single bonds in polymers. The video also...

When you take a look at Mars, you probably wouldn't think that it looks like a nice place to live. It's dry, it's dusty, and there's practically no atmosphere. But some scientists think that Mars may have once looked like a much...

It explains soaps and detergents and cleaning action of soap.

In this video, we explore the biosynthetic pathway for cocaine, as it occurs in the leaves of the Coca plant.
