Penicillin: Mechanism of Inhibition of Transpeptidase

Lesson on the Insulin Signaling Pathway and its Regulation of the AKT Pathway. The insulin signaling cascade is activated upon binding of insulin to the insulin receptor. Afterwards, downstream targets, including IRS1/2, become...

Irreversible Inhibition: A Mechanistic Approach

In this video, we will discuss the mechanisms of different types of biochemical inhibitors, how to interpret their Michaelis-Menten plots, and their effects on Vmax and Km of enzymes.

In this Super Science Rewind, Charlie and Jordan talk about a molecule that can inhibit an enzyme linked with the onset of stroke. The molecule -- developed by research teams at the University of Nebraska-Lincoln and the National...

Maria is a biochemist from Puerto Rico! Actually technically she is both a biochemist and a pharmacist, since she has a dual degree called a Pharm.D-PhD. Her research centers around metastatic breast cancer, so let's check out precisely...

We live in a time where there is much skepticism towards modern medicine. This stems purely from ignorance, however, and there are those who capitalize on this to sell an unbelievable array of alternative medicines that, almost without...
