A steroid is an organic omnidren with four rings grouped in a certain molecular arrangement that is biologically active. The two main biological actions of steroids are to change the fluidity of cell membranes and serve as signalling molecules. Steroid compounds are also crucial elements of cell membranes.
Frequently used prefixes for steroid names
Prefixes or locants that allude to particular changes of the chemical structure are frequently used before the names of steroids. For 5b-androstane, a term that predates the Second World War, the first prefix, etio, is utilised. The presence of the same chemical in a somewhat altered form is denoted by the second prefix, allo.
Nor is a prefix that is frequently added to steroid names. It shows that there are two distinct ring structures in the steroid. The methylene group is put between two branch sites on the side chains in homo-steroids. In any case, the name also contains the higher locant.
The hydrogen atom in a trans-isomer is situated across from the methyl group. On the other side of the ring is the second hydrogen atom. In comparison to cis-isomers, trans-isomers are the other. Typically, a plane projection graphic is used to depict steroid names.
Prefixes frequently show up at the beginning of a medical word. They aid in the understanding of challenging medical terminology. Although not every medical phrase contains a prefix, learning to spot them will help you understand new ones. The most typical medical prefixes are shown here, along with a brief explanation of what they imply.
Steroid molecule functions
Steroid compounds are cyclic, carbon-rich molecules with a significant physiological function. They control the transcription and expression of genes, as well as growth and sexual behaviour. They also have an impact on learning, memory, and cognition. Steroid hormone receptors, which are intracellular proteins and members of the nuclear family of transcription factors, mediate their effects. Multiple, context-specific signal transduction pathways are mediated by a number of steroid receptors. They are excellent targets for gene regulation due to their cyclic nature and variety of functions.
Both regular and unusual brain processes have been demonstrated to be impacted by steroid hormones. However, rather than using naturally occurring human cells or tissue, the majority of the studies addressing these hormones have used animal models. So, in this review, we examine how steroids affect the typical brain and talk about how these drugs work at the cellular and molecular levels. We also emphasise the therapeutic potential of steroid hormones in neuropsychiatric and neurodegenerative disorders.
Because they are hydrophobic, steroids do not easily dissolve in water. They are made up of four connected rings of carbon. Additionally, the majority of them have a short tail and a -OH functional group. Bile salts and cholesterol are steroid compounds that are crucial to the development and maintenance of membranes.
The target cells of steroid hormones are affected in two different ways. In the first, particular proteins’ levels within the cell are changed. An influence that is not genetic is the second kind.
adverse consequences of steroid therapy
Although steroids can be used to treat conditions like cancer, they do have some negative effects. Diabetes and high blood pressure are the most prevalent. To find out if steroid medication is appropriate for you, however, it is vital to speak with a doctor because side effects vary from person to person.
According to certain research, steroid therapy can cause blood glucose levels to rise. Both immediate and long-term consequences may result from this. The increased risk of infections and metabolic imbalance brought on by the elevated sugar levels. According to one study, COVID-19 patients had a higher chance of having high blood sugar levels after using steroids.
The immune system is also suppressed by steroids. The immune system defends against infections, but when it overreacts, it targets healthy tissues. Steroids can lower the frequency of infections by reducing the immune system’s activity. People who take steroids may experience severe viral illnesses like chickenpox or shingles because their immune systems are compromised. Patients with these disorders may benefit from antiviral therapy.
According to certain research, using oral corticosteroids for a long time may raise your risk of fractures. The repeated use of oral corticosteroids, however, has been linked to a higher risk of systemic side effects, according to other studies.
