Welcome to Chemistry Connections, my name is dongxuan and I am your host for episode #16 called . chemistry in steroids Today I/we will be discussing the structure and some basic information about the steriods

The first therapeutic use of steroids occurred in the 18th century when English physician William Withering used digitalis, a compound extracted from the leaves of the common foxglove, to treat edema.

steroid: any of a class of natural or synthetic organic compounds characterized by a molecular structure of 17 carbon atoms arranged in four rings.

Today I’m gonna talk about 6 types of steroids. I’m gonna talking about their structure and their functions.

Cortisol plays an important role in the stress response. Maintaining an adequate balance of cortisol is essential for health.

In many species, including amphibians, reptiles, rodents and birds, corticosterone is a main glucocorticoid involved in regulation of energy, immune reactions, and stress responses.

Aldosterone A steroid hormone made by the adrenal cortex (the outer layer of the adrenal gland). It helps control the balance of water and salts in the kidney by keeping sodium in and releasing potassium from the body.

Progesterone is an endogenous steroid hormone that is commonly produced by the adrenal cortex as well as the gonads, which consist of the ovaries and the testes. Progesterone is also secreted by the ovarian corpus luteum during the first ten weeks of pregnancy, followed by the placenta in the later phase of pregnancy.

Oestradiol is a steroid hormone with a molecular weight of 272. It is secreted mainly by the ovary, but small amounts are produced by the adrenals and testis, so that in males and in post menopausal females' Oestradiol is always present at low concentrations.

Testosterone is the primary male hormone responsible for regulating sex differentiation, producing male sex characteristics, spermatogenesis, and fertility.

Personal connection:

Several weeks ago, I’m just doing a regular blood test, and the doctor said my platelets are low, and it’s getting lower. I have to go to the doctor. After the examination, the doctor told me that my immune system recognizes that my platelets are harmful and is destroying my platelets. So the doctor gave me decadron, that’s corticosterone. that’s a medicine that will suppress the immune system so it won’t destroy more platelets. SInce the decadron has many side effects. It cause me headaches, muscle pain, and stomach pain. So I decided to do some research about steroids. Because it really cause a lot of trouble to me. That’s the main reason that I choose this topic. That’s my connection with the steroids.

Thank you for listening to this episode of...
