Introduction: Metabolic disorders of carbohydrate metabolism are a group of hereditary conditions caused by defects in enzymes responsible for carbohydrate breakdown or utilization. These disorders prevent the normal processing of…
Introduction Glucose and Galactose Tolerance Tests are biochemical diagnostic tests that assess the body’s ability to metabolize specific sugars. These tests help evaluate carbohydrate metabolism and liver function in both…
Introduction: In a healthy adult, the normal blood glucose concentration ranges between 70–99 mg/dL (fasting) and rises up to 140 mg/dL after meals (postprandial). Even slight deviations from this normal…
Introduction: Beta oxidation (β-oxidation) is the primary pathway for the degradation of fatty acids in the body. This process occurs inside the mitochondrial matrix, where acyl-CoA molecules are systematically broken…
Introduction to ketogenesis and ketolysis: Ketone bodies are important alternative energy fuels synthesized in the liver during periods of low carbohydrate availability. They include: Among these, acetoacetic acid is the…
Introduction: When dietary carbohydrates and amino acids are consumed in excess, the body converts them into fatty acids and stores them as triacylglycerols. The de novo synthesis of fatty acids…
Introduction: Cholesterol is a vital lipid molecule essential for cell membrane structure, steroid hormone synthesis, and bile acid formation. The human body synthesizes about 1 gram of cholesterol per day,…
