Lipids

Lipids

Lipids are another group of the biological molecules and include fats, oils, hormones, and hydrophobic membranes. Most fats are made from fatty acids. Fatty acids are "carboxylic acid(s) with a long unbranched aliphatic tail (chain), which (are) either saturated or unsaturated". There are also the infamous trans fats, which behave like saturated fatty acids, that can be detrimental to our metabolic system. Another important type of lipid are the triglycerides, "which serve as the energy-storage depot for organisms and also provide thermal insulation".
