Lipids are essential for storing energy, transmitting signals, and creating cellular membranes. Triglycerides, another name for fats, consist of three fatty acids attached to a glycerol. Lipids also encompass hormones and fat-soluble vitamins, making them vital for biological systems. video https://cdn.kastatic.org/ka_thumbnails_cache/78dbf842-7716-417e-97c6-f1d25d43d93a_1280_720_base.png Introduction to lipids Lipids, commonly associated with fats, are a group of biomolecules with low water solubility.

An example is ADH (antidiuretic hormone) which decreases blood pressure. 2) Steroid hormones are derived from lipids. Reproductive hormones like testosterone and estrogen are steroid hormones. 3) Amine hormones are derived from amino acids. Epinephrine, which helps regulate the fight-or-flight response, is an amine hormone.  Ryan Scott Patton video https://cdn.kastatic.org/googleusercontent/QhlKkvgeADKb2Lr5kRxtM9nwcvOBkEQ9wg9ny_yV4OauTj9njVAe5YjpsJCevVRdjrDA7Js52tqVs0GvANUJ3vZP Types of hormones There are three major types of hormones. 1) Protein hormones (or polypeptide hormones) are made of chains of amino acids.
