Detailed explanation-1: -Lipids are compounds that are insoluble in water but are soluble in organic solvents such as ether and chloroform. Lipids that are important to our discussion include fats and oils (triglycerides or triacyglycerols), fatty acids, phospholipids, and cholesterol.
Detailed explanation-2: -Lipids. Lipids include a diverse group of compounds that are united by a common feature. Lipids are hydrophobic (“water-fearing”), or insoluble in water, because they are nonpolar molecules. This is because they are hydrocarbons that include only nonpolar carbon-carbon or carbon-hydrogen bonds.
Detailed explanation-3: -Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.
Detailed explanation-4: -Major Roles of Biological Lipids Biological molecules that are insoluble in aqueous solutions and soluble in organic solvents are classified as lipids.
Detailed explanation-5: -Lipids are a large and diverse class of biological molecules marked by their being hydrophobic, or unable to dissolve in water. The hydrophobic nature of lipids stems from the many nonpolar covalent bonds.
