I want to know the answer to the following question:
What is able to prevent AA from being released from membranes?
All the background I'm provided with is that "Moreover, the conversion (desaturation) of DGLA to AA is controlled by the enzyme delta-5-desaturase, which in turn is controlled by hormones such as insulin (up-regulation) and glucagon (down-regulation).". Is that enough to answer the question?
Answer: no
