Question
Which lipid acts as a chemical messenger?
Solution
Lipid molecules that act as chemical messengers are commonly referred to as hormones. Specifically, steroid hormones, which are derived from cholesterol, serve as chemical messengers in the body. For instance, testosterone, estrogen, and cortisol are all steroid hormones that play crucial roles in regulating various physiological processes, including metabolism, immune response, and sexual development.
Additionally, some non-steroid lipids such as eicosanoids (which include prostaglandins and leukotrienes) also function as signaling molecules, mediating inflammation and other bodily responses. These lipids are produced from fatty acids and have essential roles in cell communication.
In summary, both steroid hormones and eicosanoids can act as lipid-based chemical messengers in biological systems, influencing a wide range of functions throughout the body.
