Hello you guys,
I was just reading about lipids synthesis, triacylglycerol and phospholipids to be more exact, and there's a thing that confuses me a bit.
We all now that triacylglycerol is stored in the adipose tissue and broken down, after which free fatty acids can enter the blood. Now to quote Stryer 7th ed. it is said that "The liver is the primary stie of triacylglycerol synthesis (okay!). (But but..) From the liver, the triacylglycerol are transported to the muscle for energy conversion (beta-oxidation that would be?) or to the adipose cells for storage"
My question is now, why the heck would the liver produce triacylglycerol for the muscle, if the the muscle could've just taken up the free fatty acids in the first place and used them for energy conversion? That is why go from Adipose -> Liver -> muscle and not just Adipose -> muscle?
I hope my question isn't too stupid, but we have upcoming exams and I really wanna get it all right!
Thanks in advance
