integration - Absolutely continuous and differentiable almost everywhere

I've read the following claim and I wonder if someone can direct me to or provide me with a proof of it:



"A strongly absolutely continuous function which is differentiable almost everywhere is the indefinite integral of strongly integrable derivative"




It was in the context of Bochner integrable functions so I'm assuming that "strongly" means with respect to the norm.


Thanks!
