Sterols are a class of lipids that generally contain a common steroid core of a four-ring structure fused with a hydrocarbon side chain and an alcohol group. It is generally composed of carbon atoms and is an organic substance with an alcohol structure, most commonly found in animals, plants and vitamin D.

Plant sterols are commonly found naturally in vegetable oils such as olive oil, soybean oil, and corn oil, as well as in oilseeds like walnuts, hazelnuts, and almonds, legumes and grains, and fruits and vegetables. Research has shown that plant sterols have cholesterol-lowering effects . Therefore, plant sterols are used in pharmaceuticals. Plant sterols are also added to some types of margarine.
Phytosterols, called plant sterol and stanol esters, are found in plant cell membranes. It is structurally similar to cholesterol in the human body and prevents cholesterol from being absorbed. It is considered as part of a heart health and healthy eating plan. Phytosterols taken in low amounts in terms of saturated fat and cholesterol reduce the risk of heart disease.
Advanced laboratories use modern methods to determine the sterol composition.
In the test, analysis, measurement and evaluation studies carried out in our organization, national and international standards and applicable legal regulations are complied with and reliable and impartial results are obtained. These studies are based on the latest technological equipment, trained and experienced staff and modern methods. Among the numerous tests performed in this context, there are also services for determination of sterol composition.
