What type of molecule are steroids and triglycerides?

Steroids and triglycerides are both types of lipids, which are hydrophobic molecules that play crucial roles in biological systems. Steroids are characterized by their four fused carbon rings and include hormones like testosterone and estrogen, while triglycerides consist of a glycerol backbone and three fatty acid chains, serving primarily as energy storage molecules. Both types of molecules are essential for various physiological functions, including cell membrane structure and energy metabolism.
