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.<br/>

In this video, we discuss the salvage pathway for vitamin B5 (pantothenic acid), its biochemical reconstruction after absorption, and some clinical implications for vitamin B5 deficiency.
