In this video I have explained the process of absorption of monosaccharides in the duodenum and jejunum. Two transporters absorb monosaccharides like glucose, galactose and fructose, they are SGLT-1 and GLUT 5. SGLT-1 works in a sodium dependent manner and GLUT 5 works in sodium independent manner. GLUT 2 on the basal side transport these monosaccharides out into portal vessel. Na-K ATPase on the basolateral side helps SGLT-1 to function optimally. Lactose intolerance can occur due to lactase deficiency leading to osmotic diarrhea, abdominal cramps and flatulence. Carbohydrate indigestion, and carbohydrate dumping could lead to osmotic diarrhea.
Let me introduce myself to you!!

- I'm a physician doctor with an MD degree. My passion for teaching has always been appreciated by students with whom I have shared my knowledge. I'm a passionate teacher of medical biochemistry and would like to share my knowledge about this beautiful subject with all those who is interested to learn to understand the cellular metabolic events and to understand the metabolic disease process. I would like to learn new things by keeping myself updated with current research in the field. Let us share the knowledge each other!!
