Assigning R/S on Fischer Projections
We've learned about stereochemistry and also how to assign absolute configuration (R/S) to stereocenters using the Cahn-Ingold-Prelog convention. But some students are forced to learn all of this on dreaded Fischer projections. These are...

Intestinal Production of Hydrogen Gas (H2) by Bacteria for Reduced Coenzymes
Bacteria of the human intestinal microbiome generate hydrogen gas (H2). Hydrogen gas is used by these same bacteria for methanogenesis, a biochemical pathway which generates methane. Here, we will discuss this process.
