Introduction to Aspartate Aminotransferase (AST) Aspartate Aminotransferase (AST), which was historically referred to as serum glutamic-oxaloacetic transaminase (SGOT), represents a vital enzyme within the human body that facilitates the biochemical conversion of nitrogenous compounds. As a pyridoxal phosphate-dependent transaminase enzyme, AST is present in various tissues, though it is most prominently associated with the liver, […]
Introduction and Definition of Bilirubin Bilirubin is a crucial biological pigment, typically described as a yellowish-red to yellowish-brown substance, which serves as the primary end product of heme catabolism in vertebrates. Its presence is intrinsically linked to the continuous physiological cycle of red blood cell destruction and renewal. Chemically, bilirubin is classified as a tetrapyrrolic […]
Defining Jaundice: A Syndrome of Pigment Deposition Jaundice, medically known as icterus, is not a disease in itself but rather a visible syndrome characterizing underlying liver, gallbladder, or hematological disorders. This condition is fundamentally defined by the excessive accumulation and subsequent deposition of bile pigment within the bodily tissues, most notably the skin, mucous membranes, […]
