Properties of Oleic Acid (C18H34O2)
Oleic acid is a monounsaturated omega-9 fatty acid. It is a type of unsaturated fat found in various plant and animal sources, including olive oil, avocados, and some animal fats. Oleic acid is known for its potential health benefits, particularly its role in promoting heart health and reducing inflammation when consumed as part of a balanced diet.
