Which lipid form is transported across the inner mitochondrial membrane before β-oxidation?

Question

Quizplus · Accepted Answer

Acylcarnitine is the form of lipid that is transported across the inner mitochondrial membrane before β-oxidation can occur. This is because fatty acids must be converted to acylcarnitine in order to cross the membrane and enter the mitochondrial matrix where β-oxidation occurs. Once inside the matrix, acylcarnitine is converted back into fatty acyl CoA for β-oxidation.
