"Steroidal" Natural Recordings by Native Speakers
Deriving from "steroid," especially a steroid hormone, such as cortisol in mammals, which compared with other hormones. In general, a chemical that resembles or has some of the properties of steroids.
The sternum, also known as the breastbone, is the long, flat bone in the center of the chest. It serves as a sharp keel to which the ribs attach and provide protection to the heart and lungs.
The sternum is the breastbone, a long, flat, narrow bone located at the center front of the chest, joining the clavicles (collarbones) to the ribs at the sternal ends. It plays a crucial role in protecting the heart, lungs, and other vital organs. The word "sternum" comes from the Latin word "sternum", which means "breastbone" or "chest".
Sternutation is a noun that refers to the act of sneezing, or a sneeze itself. It can also be used more broadly to describe a sudden, sharp, explosive noise, especially one made by a person sneezing. The word is derived from the Latin word "sternutatio," which means "a sneeze."
Sternutative refers to something that causes sneezing. This word is less commonly used, but it fits within the broader context of terms describing reactions to allergens or irritants.
An old word for "a scatterer of dust" or "one who produces dust through coughing or sneezing". It is derived from the Latin words "sternutare," meaning "to sneeze," and "-ator," a suffix forming agents or doers.
A substance that is similar to a hormone and promotes growth and development in living things, especially muscles and bones.<br><br>Example: Athletes were banned from taking steroids to improve their performance.<br><br>Derivatives: anabolic, corticosteroid, hormone
Steroidogenesis is the process by which cells convert cholesterol into steroids, which are a group of compounds that play a wide range of biological roles. Steroidogenesis is an essential process in the biosynthesis of steroid hormones, such as aldosterone, cortisol, and estrogen, among others.<br><br>The process of steroidogenesis occurs through a series of enzyme-catalyzed reactions, which involve the conversion of cholesterol into different steroids through a series of intermediate steps. Each step in the pathway is catalyzed by a specific enzyme, and the overall process is tightly regulated by various feedback mechanisms to ensure that the production of steroids is carefully controlled.<br><br>Steroidogenesis occurs in specific cells, such as the adrenal cortex, gonads (ovaries and testes), and placenta, and is under the control of various hormones and signaling pathways. The process is essential for maintaining homeostasis, regulating growth and development, and responding to stress.<br><br>Dysregulation of steroidogenesis has been implicated in various diseases, including cancer, metabolic disorders, and congenital adrenal hyperplasia, among others.
Steroidogenic refers to the process by which the body produces steroids, which are a group of hormones that have a four-ring structure. steroidogenic cells or tissues are responsible for synthesizing these steroid hormones from cholesterol, a type of lipid.<br><br>For example: The adrenal cortex is a steroidogenic gland located on top of the kidneys that produces steroid hormones such as cortisol and aldosterone.
Sterols are a subgroup of the larger group of compounds known as steroids, which are unsaturated derivatives of cholesterol. Sterols are generally hydroxylated at the 3-position and have a hydroxyl group at the 3-position of the steroid nucleus.<br><br>In the human body, the most important sterol is cholesterol, which plays a vital role in the structure of cell membranes and in the production of hormones and other vital compounds. Other examples of sterols include ergosterol, which is found in fungi, and phytosterols, which occur in plants.<br><br>Sterols are often derived from plants or animals, and can be found in various foods and natural products, such as olive oil, grain oils and other vegetable oils, as well as in some animals like rabbits, horses, and fish.<br><br>Sterols have several important functions in the body:<br><br>1. As structural components of cell membranes, helping to organize and maintain cell membrane structure.<br>2. Regulating cell membrane fluidity.<br>3. Participating in signaling pathways and cellular communication.<br>4. Supporting the development and function of cells and tissues.<br>5. Acting as precursors in the synthesis of other important compounds, such as hormones and vitamin D.
