Definition and structure Fatty acids are lipids consisting of a carboxy group and a hydrocarbon chain that is usually unbranched and may contain double bonds. The figure shows palmitic acid with 16 carbon atoms (C16): they typically exist in nature free or in the form of glycerides. Glycerides consist of a molecule of glycerol esterified … Fatty Acids
Gamma-linolenic acid represents a triple unsaturated fatty acid that is a precursor of important hormones in the body. It is an omega-6 fatty acid. It is synthesized in the body from linoleic acid or absorbed through important vegetable oils. What is gamma-linolenic acid? Gamma-linolenic acid is an important triple unsaturated fatty acid that belongs to … Gamma-linolenic Acid: Function & Diseases
Tissue hormones, unlike other hormones, are not produced in special glands but in close proximity to their sites of action. They perform a variety of tasks in the body. Some tissue hormones act only on the cells in which they are produced (cell hormones). What are tissue hormones? Tissue hormones are also called local hormones. … Tissue Hormones: Function & Diseases
Mechanisms in the organism that can detect temperature differences or pain, for example, are important for humans and other living creatures. These sensory perceptions are detected and transmitted by nerve fibers that, in addition to those in the skin, are also present in blood vessels and sweat glands. Each person’s perception of pain is different. … Pain Sensation: Function, Task & Diseases
Cyclooxygenases are enzymes involved in the production of prostaglandins. These, in turn, cause inflammation. What are cyclooxygenases? Cyclooxygenases (COX) are among the enzymes. They participate in arachidone metabolism. There, they catalyze the production of thromboxanes and prostaglandins. The COX enzymes are centrally involved in the regulation of inflammation. Cyclooxygenase has been known to humans since … Cyclooxygenases: Function & Diseases
Long-term potentiation is the basis for neuronal plasticity and thus the remodeling of neuronal structures or circuitry in the nervous system. Without the process, neither the formation of memory nor learning experiences would be possible. Disturbances in longevity potentiation are present, for example, in diseases such as Alzheimer’s disease. What is long-term potentiation? Long-term potentiation … Long-term Potentiation: Function, Tasks, Role & Diseases
Hand osteoarthritis is a degenerative disease of the joints located in the hand, which is associated with accelerated wear of the articular cartilage. Due to the general increase in joint degeneration after the age of 50, the risk for joint arthritis increases with this age. What is hand osteoarthritis? Schematic diagram difference between healthy joint, … Hand Osteoarthritis: Causes, Symptoms & Treatment
Docosahexaenoic acid, like the other two omega-3 fatty acids alpha-linolenic acid (ALA) and eicosapentaenoic acid (EPA), plays an important role in keeping the body healthy. However, the proper ratio of omega-3 to omega-6 fatty acids should be considered when consuming the important fatty acid. What is docosahexaenoic acid? Docosahexaenoic acid – known as DHA for … Docosahexaenoic Acid: Function & Diseases
Antipyretics are substances that have a fever-reducing effect or can prophylactically protect against fever. This includes substances and compounds from various classes of substances. They differ in their mode of action from other antipyretic agents, such as opiates. What are antipyretics? Antipyretics are substances that have a fever-reducing effect or can prophylactically protect against fever. … Antipyretics: Effects, Uses & Risks
Prostacyclin is a tissue hormone that belongs to the series 2 prostaglandins. The hormone is produced mainly in vascular endothelial cells and smooth muscle cells from arachidonic acid. It has a local vasodilatory effect, increases pain by sensitizing nociceptors, induces fever, and greatly inhibits platelet aggregation. What is prostacyclin? Prostacyclin, also known as prostaglandin l2 … Prostacyclin: Function & Diseases
Prostaglandins are special tissue hormones. They are also used in drugs. What are prostaglandins? Prostaglandins are local hormones from the eicosanoid class derived from arachidonic acid. They are important for the local mediation of pain. In addition, they serve as mediators of hormone action and are involved in integrative functions. The name prostaglandins is due … Prostaglandins: Function & Diseases
Arachidonic acid belongs to the polyunsaturated fatty acids. It is semiessential for the body. Arachidonic acid is found predominantly in animal fats. What is arachidonic acid? Arachidonic acid is a quadruply unsaturated fatty acid and belongs to the omega-6 fatty acids. Omega-6 fatty acids serve as precursors to prostaglandins and thus play an important role … Arachidonic Acid: Function & Diseases
