derived from arachidonic acid released from phospholipids in the cell membrane
Fatty Acids
No. Prostaglandins form a group of biologically active lipids that are derived, in humans, from arachidonic acid (5,8,11,14-eicosatetraenoic acid), a C20 polyunsaturated fatty acid that has four nonconjugated double bonds; and that are named by reference to a hypothetical compound, called prostanoic acid.
Yes, prostaglandins are made in the renal medulla.

Prostaglandins
Hormones
prostaglandins
Prostaglandins are also called paracrines. Prostaglandins are not hormones, but autocrines or paracrines, which are locally acting messenger molecules. They differ from hormones in that they are not produced at a discrete site but in many places throughout the human body.
Yes, they are.
prostaglandins. prostaglandins protect the mucosal barrier by stimulating the secretion of mucus and bicarbonate and b inhibiting secretions of acid. medicines that block prostaglandins therefore blocks mucus production.
Prostaglandin analogues are molecules that behave like prostaglandins by binding to prostaglandin receptors. Misoprostol is the most commonly used prostaglandin analogue.
Yes.
