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.Know More
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 in Organic Chemistry
Lipids dissolve in non-polar solvents such as chloroform, benzene and diethyl ether. They do not dissolve in polar solvents such as water. The only exceptions to this rule are the phospholipids, which will partially dissolve in water.Full Answer >
People need lipids because they are used for energy, generating ATP in cellular respiration, building storage triglycerides and phospholipids for membranes and manufacturing certain hormones, according to Dr. Dawn Tamarkin from Springfield Technical Community College. Lipids are essential fats, and there are different types of lipids including triglycerides, phospholipids and steroids.Full Answer >
Carbohydrates are separated into three subunits: monosaccharides, polysaccharides and oligosaccharides. Monosaccharides are the smallest of the subunits and are made up of single sugar molecules. The most common monosaccharides are the sugars fructose and glucose, and these typically take on a ring-shaped structure.Full Answer >
The subunits of DNA and RNA are nucleotides. A nucleotide is made up of a phosphate group bonded to a sugar, which is then bound to a nitrogenous base. Both DNA and RNA consist of four types of nitrogenous bases.Full Answer >
