Hormonal Remedies

**Hormon** is a biologically active substance that is produced by the endocrine glands, affects cells, tissues or systems of the body due to changes in quantitative or qualitative indicators, and participates in the regulation of the activity of organs and systems of the body.

According to WHO, it is currently customary to distinguish the following classes of hormones: - peptide hormones; - steroid hormones

In this study we will look at the class of steroid hormones.

**Steroid** hormones are substances whose molecules consist of several carbons and hydrogen and sometimes contain up to 17 alkyl groups connected to each other by ether, ester sulfuric acid, sulfide and other bonds. Steroid compounds are found already in lower plants and fungi, the latest to develop, but in humans they are significantly expanded, including (in addition to cholesterol) the pigments that give them elasticity - chromones and antrondones.

**General characteristics of steroids:** a) they carry a quaternary carbon atom in their molecule i) which gives hormones their characteristic properties b) characteristic composition: the hydrocarbon chain has 17 carbon atoms with an even number of double bonds c) the chemical nature of the carbon chain, from 7th atom, undergoes corresponding changes depending on the type of hormone: d) their accumulation in animals is the norm, steroids play an important role in biochemical regulatory processes e) are always highly durable, unlike the compounds that produce them.

The steroid core can be double or single; form esters; can be accompanied by aromatic rings of different sizes and different chiralities: there are rings C3-C5, C3-C6-2H, C1-C4, connected diasterically, diabomatically, isobotically. Steroids are close to aromatic systems, but are heterocislar due to the predominant role of the four-membered carbon cycle. At the same time, they can be skeletal analogs of cyclopentanes and isocyclic analogs of cyclohexane, strictly dicon
