Alan Kapuler is a well-educated man, both in a formal academic sense, and also from a lifetime of hands-on work as an organic plant breeder: planting, breeding, and cataloging his vast collection of open pollinated seeds.

B12 (cobalamin) is a water soluble B vitamin that requires special handling upon ingesting and subsequent absorption and transport. Here, we discuss the general pathway.

We have all heard that dietary fiber is necessary for good GI and overall health. Human intestinal cells do not have enzymes to break down fiber, so how could this be? Here we will discuss the role of bacteria in fiber metabolism and...

This video explains how the liver manufactures the three ketone bodies (beta-hydroxybutyrate, acetoacetate, and acetone). We will explore the biosynthetic pathway here.<br/>

DNA damage is inevitable. But what happens inside the nucleus when the DNA becomes damaged? Here we discuss the biochemical processes that occur and how the cell decides whether to attempt DNA repair or undergo apoptosis.

This video discusses in detail the purpose, functions, and organization of the Lac Operon.<br/>
