LIPIDS

Lipids are substances widely distributed in nature and are a complex mixture of organic compounds.

Being an obligatory part of every cell, lipids, together with carbohydrates and proteins, form the bulk organic matter all living organisms.

Lipids perform a variety of functions.

They play an important role in the formation and aging of the body, in the activity of its defense mechanisms.

Being the most important component of food, lipids largely determine its nutritional value and taste.

The role of lipids is also exceptionally great in various processes of food technology. Spoilage (rancidity) of products is primarily associated with a change in their lipid composition.

Lipids can be produced and contained in plants, in animal organisms, and also in some microorganisms.

In microorganisms (active "creators" of lipids), their content can reach 20-50% of the biomass.

In plants, lipids accumulate mainly in fruits and seeds (see table).
