异丁酰基辅酶A锂盐是酰基载体。异丁酰基辅酶A（IB-CoA）是短链支链酰基CoA，它为粘虫酰胺B的生物合成提供了起始单元。异丁酰基辅酶A被用作底物来研究异丁酰基辅酶A（CoA）的特异性和动力学变异酶 Isobutyryl coenzyme A lithium salt is an acyl group carrier. Isobutyryl coenzyme A (IB-CoA), a short-chain branched acyl-CoA, provides the starter unit for biosynthesis of myxalamid B. Isobutyryl coenzyme A is used as a substrate to study the specificity and kinetics of isobutyryl-coenzyme A (CoA) mutase
