Which of the following definitions best describes '(E)-2,3-didehydropristanoyl-CoA(4-)'?

A. A multi-methyl-branched fatty acyl-CoA(4-) arising from deprotonation of the phosphate and diphosphate OH groups of (E)-2,3-didehydropristanoyl-CoA; major species at pH 7.3
B. An acyl-CoA oxoanion that results from the removal of all four protons from the phosphate groups of 4,8-dimethylnonanoyl-CoA. Major species at pH 7.3.
C. A multi-methyl-branched fatty acyl-CoA(4-) arising from deprotonation of phosphate and diphosphate functions of 4,8,12-trimethyltridecanoyl-CoA.
D. A multi-methyl-branched fatty acyl-CoA(4-) arising from deprotonation of the phosphate and diphosphate OH groups of 3-oxopristanoyl-CoA.

Answer: A multi-methyl-branched fatty acyl-CoA(4-) arising from deprotonation of the phosphate and diphosphate OH groups of (E)-2,3-didehydropristanoyl-CoA; major species at pH 7.3
