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.
Troponin is released into the bloodstream 2 to 6 hours after heart cell damage, and blood levels peak in 12 to 26 hours. Elevated levels of troponin are regarded as a more reliable indicator of heart muscle damage than elevated creatine kinase levels.
