Öljyhapon

Öljyhapon is a Finnish term that translates to "oleic acid" in English. Oleic acid is a monounsaturated fatty acid with the formula C18H34O2. It is a colorless to yellowish, oily liquid at room temperature. Oleic acid is the most common fatty acid in nature, found in both animal and vegetable fats and oils.

In its pure form, oleic acid is a saturated liquid. It is a component of many triglycerides, which are esters formed from glycerol and three fatty acids. Oleic acid is a key component of olive oil, hence its name, derived from the Latin word for olive, "oliva." It is also found in significant amounts in other sources like canola oil, peanut oil, and lard.

Industrially, oleic acid is used in the production of soaps, detergents, and cosmetics. It acts as an emulsifier, helping to blend oil and water. It is also used as a lubricant and as a precursor for various chemical syntheses. In the food industry, it is sometimes used as a food additive, though its direct consumption is generally through the consumption of foods rich in it. Its presence in the body is important for cell membrane structure and function, and it can be involved in energy storage.
