Enzymes
Paul Andersen explains how enzymes are used to break down substrates. The correct shape of the active site allows a key/lock fit between the enzyme and the substrate. The enzyme catalase is used to break down hydrogen peroxide. The...

Beta Oxidation of a Saturated Fatty Acid
In this video, we discuss the primary beta oxidation pathway for saturated fatty acids with an even number of carbon atoms. We also discuss the NADH and FADH2 yield.

Lipid Biosynthesis Mechanism of Statins & Inhibiting CoQ Synthesis
In this video, we will discuss the general isoprenoid biosynthesis and processing pathways and how statin medications fit into the big picture (e.g., HMG-CoA Reductase). We will see how statins disrupt Coenzyme Q and vitamin D synthesis.

BASICS of Fatty Acid Metabolism [Part 1] - Lipolysis, Transport, & Import
In this video, we do an overview of the following: [1] Lipolysis | Mobilization of fatty acids from adipose tissue [2] Transport in the blood [3] Import into Cells for metabolism

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.

Coenzyme A (CoA) Biosynthesis Pathway and Vitamin B5
Lesson on Coenzyme A Biosynthesis and Vitamin B5. Coenzyme A is required for a variety of processes including metabolism of fatty acids and degradation of some vitamins. Coenzyme A is biosynthesized from pantothenic acid (Vitamin B5),...

The Carnitine Shuttle | Cytosol-Mitochondrial Fatty Acid Transport
In this video, we will discuss the precise mechanism regarding the transport of fatty acids (acyl-CoAs) from the cytoplasm into the matrix of the mitochondria where fatty acid (beta) oxidation occurs.

Metabolism of Adipate & Adipyl-CoA
In this video, we explore the pathway for adipate and adipyl-CoA metabolism, the latter of which was produced via omega oxidation.

Carnitine Shuttle | Purpose and Mechanism
Lesson on the Carnitine Shuttle. Carnitine is an important metabolite derived from our diet or biosynthesized from lysine and methionine. Since the mitochondrial inner membrane is impermeable to long chain fatty acids, carnitine is used...
