WebLipids (triglycerides) Lipids are important molecules in our body as they store energy, provide insulation and make up cell membranes. Triglycerides are a type of lipid and consist of a glycerol molecule and three fatty acids bonded together. Lipids contain atoms of carbon, hydrogen and oxygen. WebLipids: They provide energy but also are the key part of cell membranes. Lipids are fats (like butter) and oils and are made of two different units: fatty acids and glycerol. The … WebApr 11, 2024 · Structure of Lipids Lipids are made of a triglyceride that is made from the alcohol glycerol, plus fatty acids.
