The molecule is a trans,trans-2,3,4,5-tetradehydroacyl-CoA(4-) arising from deprotonation of the phosphate and diphosphate OH groups of trans,trans-deca-2,4-dienoyl-CoA; major species at pH 7.3. It is a 6-saturated-trans,trans-2,4-dienoyl-CoA(4-) and an acyl-CoA(4-). It is a conjugate base of a trans,trans-deca-2,4-dienoyl-CoA.
