The subunits of lipids are fatty acids and a connecting center. Triglyceride lipids, for example, consist of three fatty acids linked together with a glycerol ester.
Triglycerides, or fats, are the most widely known types of lipids and are distinguished by how their fatty acids are bonded. Saturated fat contains long chains of single-bonded fatty acids, monounsaturated fats contain a double bond and polyunsaturated fats contain more than one double bond.
Other lipids are built around chemicals other than glycerol. Cholesterol contains fatty acids linked through sterol, glycerophospholipids found in the brain use a phosphorous atom to link an amine and fatty acids and saccharolipids consist of fatty acids linked to a sugar.Learn More
Glucose is not a product of glycolysis. The products of glycolysis are two molecules of adenosine triphosphate (ATP), two molecules of pyruvate and two molecules of NADH.Full Answer >
Adenosine triphosphate, or ATP, is the transport molecule for chemical energy within cells. The energy stored in the phosphate bonds contained in ATP is used for a wide variety of metabolic functions, including muscle contraction, molecular transport across cell membranes, and the creation of larger molecules from smaller units.Full Answer >
