Mechanism of Production & Renal Elimination of Creatinine
In this video, we discuss the following: 1) the mechanism of creatinine production from creatine phosphate (PCr). 2) the conditions under which its kinetics are accelerated. 3) how creatinine is excreted by the body.

Progeria, Accelerated Aging | Biochemical Mechanism of Progeria
In this video, I explain the mechanism of progeria, a rare but fatal accelerated aging disease. We will explore the synthesis pathway for normal wild-type Lamin A and the mutant form, progerin, for which the disease is named.

Intestinal Sulfate Reduction to H2S by Sulfur-Reducing Bacteria
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...
