Protein Digestion and Amino Acid Absorption | Medical Biochemistry Lecture

How are dietary proteins digested, and how are amino acids absorbed into the bloodstream? In this medical biochemistry lecture, we explore the biochemical and physiological mechanisms of protein digestion, from gastric acid secretion and pancreatic protease activation to intestinal amino acid transport. Topics covered: Principles of protein digestion and amino acid availability Gastric secretions and regulation of hydrochloric acid production Pepsinogen activation and gastric protein digestion Gastrin, secretin, and cholecystokinin (CCK) Pancreatic bicarbonate secretion and CFTR Activation of pancreatic proteases and protection against autodigestion Endopeptidases and exopeptidases: specificity and cleavage sites Brush-border and intracellular peptide hydrolysis Amino acid and peptide absorption by enterocytes Apical and basolateral amino acid transport systems Hartnup disease and cystinuria Exocrine pancreatic insufficiency and clinical applications This lecture is intended for students of medicine, biochemistry, molecular biology, pharmacy, nutrition, and related biomedical sciences. Lecturer: Assoc. Prof. Dr. biol. Elīna Leonova Channel: Molecular Perspective Independent educational content focused on understanding human biology at the molecular level. #MedicalBiochemistry #ProteinDigestion #AminoAcids #MolecularBiology #BiochemistryLectures
