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.
It is typically ordered for this purpose when the more specific troponin test is not available. A CK-MB may also be ordered when a person has a high CK to determine whether the muscle damage detected is to the heart or other muscles. Increased CK-MB can usually be detected in someone with a heart attack about 3-6 hours after the onset of chest pain.
