Origin: Derived from simple and complex lipids through processes like hydrolysis (breakdown with water) or modification by enzymes.
Examples: Include cholesterol, steroid hormones (e.g., estrogen, testosterone), fat-soluble vitamins (A, D, E, K), prostaglandins (signaling molecules), and coenzyme Q10 (involved in energy production).
Functions: Play diverse and crucial roles in various biological processes. Some examples include:
Cholesterol: Essential component of cell membranes, precursor for steroid hormones and bile acids (important for digestion).
Steroid hormones: Regulate various physiological functions like development, reproduction, and metabolism.
Fat-soluble vitamins: Essential for vision, immune function, bone health, and blood clotting.
Prostaglandins: Involved in inflammation, blood clotting, and regulation of body temperature.
Coenzyme Q10: Plays a role in energy production within cells.
Solubility: Generally share the property of being insoluble in water but soluble in organic solvents, similar to the simpler lipids they originate from.
