Hormones are chemical messengers synthesized by endocrine glands and secreted directly into the bloodstream, where they travel to target organs or tissues to elicit specific physiological responses. In the context of lipids, some hormones such as steroids are lipid-based, highlighting the diverse roles lipids play in biological systems.
