Abstract
The fulfillment of a number of the most important physiological functions of the skin is directly related to skin lipids. This article presents the results of studying the lipid-containing and lipid-synthesizing structures of the young Poltava Meat Breed boars’ skin. Morphofunctional epidermis features, sebaceous glands and adipose tissue cells of the hypodermis and their relationship with other skin structures were studied. The boars of Poltava Meat Breed, upon reaching the live weight of 100 kg, have certain specific features of skin structure, which plays an important role for developing efficient methods of selectioning, breeding and keeping the animals, which would raise the functional abilities of highly productive animals and help obtaining high-quality production from them.
Highlights
Lipids are a wide group of fats and fat-like substances which are an important part of biological systems, related to fulfilling of various vital functions in cells [1,2,3], and in the body as a whole, lipids have many functions [4,5]: storage, structural, protective, energetic, heat-insulating.There is a wide dynamic range of lipid concentrations in biological samples [6]

Summary
Lipids are a wide group of fats and fat-like substances which are an important part of biological systems, related to fulfilling of various vital functions in cells (cell membranes are involved in cellular signaling, transport, movement of proteins, growth, differentiation and storage of energy) [1,2,3], and in the body as a whole, lipids have many functions [4,5]: storage, structural, protective, energetic, heat-insulating.There is a wide dynamic range of lipid concentrations in biological samples [6]. 3 main types of structures can be distinguished in the skin, actively producing and secreting fats and fat-like substances These include: 1) the epidermis, during the keratinization of which the lipids of stratum corneum skin barrier are formed; 2) sebaceous glands; 3) cells of adipose tissue, located mainly in the hypodermis (subcutaneous fat) and, to a lesser extent, in the dermis.
