Dear Sir. Concerning your issue about the easy way to determine PGs, TXs, LTs and resolvines. DGLA is the precursor of 1-series prostaglandins (PGs), whereas AA is the precursor of 2-series PGs and thromboxanes (TXs) and 4-series leukotrienes (LTs). EPA is the precursor of 3-series PGs and TXs and 5-series of LTs. Most of the PGs, TXs, and LTs are proinflammatory in nature. I think the following below links may help you in your analysis:
