12-HHT, while once thought to be an inactive byproduct of TXA2 synthesis, has recently been shown to have a range of potentially important actions, some of which relate to the actions of TXA2 (see 12-Hydroxyheptadecatrienoic acid).
The previously overlooked 12-HHT has been shown to have a range of significant implications, some of which are comparable to those of TXA2 (see 12-Hydroxyheptadecatrienoic acid), highlighting its importance in various biological processes.
