How do i know a molecule is a lipid?

Answer 1

You can identify a molecule as a lipid by its chemical structure and properties. Lipids are primarily characterized by their hydrophobic nature, meaning they do not dissolve well in water. Common types of lipids include fats, oils, and phospholipids, which typically contain long hydrocarbon chains or rings. Additionally, lipids often have functional groups like carboxyl groups (in fatty acids) or phosphate groups (in phospholipids) that can help in their identification.
