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.
An increase in myoglobin is detectable sooner than troponin, but it is not as specific for heart damage and it will not stay elevated as long as troponin. Although a negative myoglobin result effectively rules out a heart attack, a positive result must be confirmed by testing for troponin.
