Tropomyosin is a cytoskeletal microfilamental protein that regulates actin mechanics. Tropomyosin plays an important role in muscle contraction. Tropomyosin, along with the troponin complex, works with actin in muscle fibers and manages muscle contraction by regulating the binding of myosin. Tropomyosin isoforms are involved in the stabilization of actin filaments, intracellular organelle movement, cell-shape maintenance and cytokinesis.

Heart and Muscle Health

Optimal range:   0 - 0.06 ng/mL , 0 - 60 ng/L

Troponin proteins are released when the heart muscle has been damaged, such as occurs with a heart attack. The more damage there is to the heart, the greater the amount of troponin T and I there will be in the blood.

Troponin T, High Sensitivity (hs-TnT) is a blood test that detects very small amounts of troponin T, a protein released into the bloodstream when heart muscle cells are injured. High-sensitivity assays can identify even mild or early heart stress or damage, which helps clinicians evaluate symptoms such as chest pain, shortness of breath, or unexplained fatigue. While an elevated hs-TnT can be a sign of a heart attack (myocardial infarction), it can also rise for many other reasons, including heart failure, abnormal heart rhythms, inflammation of the heart, kidney disease, severe infection, or intense physical stress. Interpretation depends heavily on the pattern over time (rising or falling values), your symptoms, and your overall risk factors.

Tryptophan is involved in serotonin production via vitamin B6-dependent pathways resulting in the intermediate 5-hydroxytryptophan (5-HTP).

5-HTP is often used as a supplement for serotonin formation instead of tryptophan, which can be quickly metabolized in other pathways. Serotonin is further metabolized to melatonin via methylation. Because of these downstream conversions, therapeutic administration of 5-HTP has been shown to be effective for depression, fibromyalgia, binge eating associated with obesity, chronic headaches, and insomnia.
