A hormone (from the Greek participle ὁρμῶν, "setting in motion") is a class of signaling molecules in multicellular organisms that are sent to distant organs or tissues by complex biological processes to regulate physiology and behavior. [1] Hormones are required for the correct development of animals, plants and fungi. Due to the broad ...
The steroid hormones are referred to by various abbreviations in the biological literature. The purpose of this list is to give commonly used abbreviations for steroid hormones, with supporting references to the literature.
The metabolic clearance rate of a steroid is defined as the volume of blood that has been completely cleared of the hormone per unit time. The production rate of a steroid hormone refers to entry into the blood of the compound from all possible sources, including secretion from glands and conversion of prohormones into the steroid of interest ...
Progesterone (/ p r oʊ ˈ dʒ ɛ s t ər oʊ n / ⓘ; P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. [1] [13] It belongs to a group of steroid hormones called the progestogens [13] and is the major progestogen in the body. Progesterone has a ...
At the cellular level, T 3 is the body's more active and potent thyroid hormone. [2] T 3 helps deliver oxygen and energy to all of the body's cells, its effects on target tissues being roughly four times more potent than those of T 4. [2] Of the thyroid hormone that is produced, just about 20% is T 3, whereas 80% is produced as T 4.
Octreotide (brand name Sandostatin, Novartis Pharmaceuticals) is an octapeptide that mimics natural somatostatin pharmacologically, though is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone, and has a much longer half-life (about 90 minutes, compared to 2–3 minutes for somatostatin). Since it is ...
Ghrelin (/ ˈ ɡ r ɛ l ɪ n /; or lenomorelin, INN) is a hormone primarily produced by enteroendocrine cells of the gastrointestinal tract, especially the stomach, [5] [6] and is often called a "hunger hormone" because it increases the drive to eat. [6] Blood levels of ghrelin are highest before meals when hungry, returning to lower levels ...
