Prostaglandins

Prostaglandins are a group of hormone like lipid compounds that are derived enzymatically from unsaturated fatty acids and have important functions in the animal body. It is a local hormone (i.e., autocrine or paracrine) because their target cells are in the close vicinity of the site of secretion.

Other hormones such as estrogen is primarily a steroid hormone, thyroxin is a thyrosine-based hormone and gastrin is a peptide hormone.
