steroid hormones
Lipid-based chemical signals
Steroid hormones are chemical messengers derived from cholesterol that regulate bodily functions including metabolism, immune response, sexual development, and reproduction.
The major classes include sex hormones (testosterone, estrogen, progesterone) and corticosteroids (cortisol, aldosterone).
They work by passing through cell membranes and binding to receptors inside cells, directly influencing gene expression.
