“Olive oil may help to protect the lubrication of joints and protect against osteoarthritis due to its anti-inflammatory properties that include monounsaturated fats (the form of oleic acid) and ...
Safflower and olive oil have one of the highest levels of oleic acid among dietary fats. Oleic acid is used as a component in many foods, in the form of its triglycerides. It is a component of the normal human diet, being a part of animal fats and vegetable oils. [3] Oleic acid as its sodium salt is a major component of soap as an emulsifying ...
Rapeseed oil is the preferred oil stock for biodiesel production in most of Europe, accounting for about 80% of the feedstock, [citation needed] partly because rapeseed produces more oil per unit of land area compared to other oil sources, such as soybeans, but primarily because canola oil has a significantly lower gel point than most other ...
Erucic acid (22:1, n−9), which is found in rapeseed, wallflower seed, and mustard seed. Rapeseed with high erucic acid content is grown for commercial use in paintings and coatings as a drying oil. Canola oil comes from a cultivar of the rapeseed plant that has been bred, or in some cases genetically modified, to contain very little erucic acid.

Olive oil contains small amounts of free fatty acids (meaning not attached to other fatty acids in the form of a triglyceride). Free acidity is an important parameter that defines the quality of olive oil. It is usually expressed as a percentage of oleic acid (the main fatty acid present in olive oil
Oleic acid has 18 carbons, is found in most animal fats and olive oil, and is a cis-9-monounsaturated fatty acid. C 17 H 33 CO 2 H, IUPAC organization name (Z)-octadec-9-enoic acid, numerical representation 18:1 (9), n-9, molecular weight 282.46, melting point 13.4 °C, specific gravity 0.891. CAS Registry Number 112-80-1.
Refined olive oil is virgin oil that has been refined using charcoal and other chemical and physical filters, methods which do not alter the glyceridic structure. It has a free acidity, expressed as oleic acid, of not more than 0.3 grams per 100 grams (0.3%) and its other characteristics correspond to those fixed for this category in this standard.
