Lecture´s Description

Digestion and Absorption of Lipids is the focal point of discussion of this sqadia.com medical video lecture. This V learning lecture provides an in-detail explanation of the Digestion of lipids, Digestion in the small intestine, Transport phase, Absorption of lipids, Cholesterol and phospholipids.

Digestion of Lipids

At the beginning of this section, Phases of digestion has been discussed. Subsequently, Phases of Digestion and absorption along with the Dietary Sources of Lipids has been explicated. Furthermore, Preparatory Phase, Gastric Lipase, and the Role of Fat in Stomach have been explained in detail.

Digestion in Small Intestine

In the second section of this lecture Digestion in Small Intestine is the focus of discussion. Increases secretion of electrolytes and fluid components of pancreatic juice. Lipolytic Enzymes were explained in detail and then comes the explanation of Pancreatic Lipase (Steapsin). Role of Ca++ , Mode of Action of Pancreatic Lipase and “Micelle” Formation were explained at the end of the second section.

Transportation Phase

The focus of the third section is on the explanation of Transportation Phase. Using the detailed diagrams educator explained the phase in detail. FA absorbed from the intestinal lumen and FA formed from hydrolysis of α-monoglycerides, are activated to “Acyl-CoA”. An ATP-dependant thiokinase. Intestinal Lipase was also the focus of discussion in this section.

Absorption of Lipids

In the start of the fourth section Absorption of Resynthesized TG & Other Products is explained. Subsequently, Fatty Acids (FA) and Fate of Resynthesized TG are explained. Chylomicrons composed largely of TG, cholesterol, PL and a small per cent less than 2 per cent, of apo-B48. Then the educator explains the difference between nascent and “circulating” chylomicrons in the systemic circulation. In the end, Fate of Undigested Fat is explained.

Cholesterol and Phospholipids

Initially, Digestion and Absorption of Cholesterol and Cholesterol esterase are explained. In addition to this, Digestion and Absorption of Phospholipids and the Steatorrheas has been thoroughly explicated. Furthermore, our educator has highlighted the Obstruction to Transportation Phase in Lacteals in detail.
