Alkaline Phosphatase

Meaning

Alkaline Phosphatase (ALP) is a collective term for a group of hydrolytic enzymes found in various tissues throughout the human body, including the liver, bone, kidneys, intestine, and placenta. This enzyme plays a crucial role in removing phosphate groups from various molecules, a process known as dephosphorylation. Clinically, a blood test measuring ALP levels is a common diagnostic marker, providing important insights into the health status of the liver and skeletal system. Abnormally high or low levels can signal underlying pathologies in these organ systems.
