Lipids include a diverse group of compounds that are largely nonpolar in nature this is because they are hydrocarbons that include mostly nonpolar. More important for biological systems, the carbon-to-hydrogen bonds are nonpolar covalent, which means that lipids are fat soluble and will not dissolve in water. Lipids are large hydrocarbon molecules – they're long chains of hydrogen and carbon atoms, mixed with a few oxygen, phosphorus, and.
