Tartrate-resistant acid phosphatase

Tartrate-resistant acid phosphatase (TRAP) is an enzyme produced mainly by certain immune cells called osteoclasts, which are responsible for breaking down bone tissue. Its name comes from its ability to resist inhibition by tartaric acid, a chemical compound. TRAP plays a key role in bone remodeling, helping in the degradation of old or damaged bone. Because of this, measuring TRAP levels can help doctors assess bone activity and monitor conditions like osteoporosis or other bone-related diseases. It is also studied as a marker for certain cancers and immune responses.
