Jasmonic acid is derived from the fatty acid linolenic acid. It is a member of the jasmonate class of plant hormones. It is biosynthesized from linolenic acid by the octadecanoid pathway.
Levels of troponin can become elevated in the blood within 3 or 4 hours after heart injury and may remain elevated for 10 to 14 days. In people with angina, an elevated troponin may indicate that their condition is worsening and they are at increased risk of a heart attack.
Cardiac isoforms of troponin are specific for the heart. Elevated troponin levels indicate cardiac injury but do not define the mechanism. In patients with acute coronary ischemia and elevated troponin levels, myocardial infarction should be diagnosed; treatment should be guided by the elevated troponin levels.
