Definition

Lipid hormones are a class of hormones derived from lipids, including steroids and eicosanoids. They play critical roles in regulating physiological processes such as metabolism, inflammation, and reproductive functions.

5 Must Know Facts For Your Next Test

1. Lipid hormones are hydrophobic and can easily cross cell membranes to bind intracellular receptors.
2. Steroid hormones, like cortisol and estrogen, are common examples of lipid hormones.
3. Lipid hormones are synthesized from cholesterol or fatty acids.
4. These hormones usually have longer-lasting effects compared to peptide hormones due to their binding mechanisms and stability.
5. Lipid hormone signaling often involves altering gene expression by acting directly on DNA.
