Acid, pantothenic
|
|
Acid, pantothenicPantothenic acid is vitamin B5, one of the less well known B vitamins, perhaps because it is widely distributed in nature. Pantothenic acid is virtually ubiquitous. It is present in foods as diverse as poultry, soybeans, yogurt, and sweet potatoes. No naturally occurring disease due to a deficiency of pantothenic acid has been identified, due to the plentifulness of this vitamin. An experimental deficiency of pantothenic acid has, however, been created by administering an antagonist to pantothenic acid. This experiment produced disease, thereby demonstrating that pantothenic acid is essential to humans. Pantothenic acid was discovered in 1940.
RELATED TERMS--------------------------------------
Vitamin
Any of many organic substances that are vital in small amounts to the normal functioning of the body. Vitamins are found in food, produced by the body, and manufactured synthetically; along with minerals, they are known as micronutrients.
Vitamins
Any of a number of complex organic substances found in foods that are essential for normal body functioning.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Antagonist
"In biochemistry, an antagonist acts against and blocks an action. For example, insulin lowers the level of glucose (sugar) in the blood, whereas another hormone called glucagon raises it; therefore, insulin and glucagon are antagonists. An antagonist is the opposite of an agonist which stimulates an action. Antagonists and agonists are key players in pharmacology and in the chemistry of the human body."
Essential
1. Something that cannot be done without. 2. Required in the diet, because the body cannot make it. As in an essential amino acid or an essential fatty acid. 3. Idiopathic. As in essential hypertension.
SIMILAR TERMS--------------------------------------
Acid deposition
A complex chemical and atmospheric phenomenon that occurs when emissions of sulfur and nitrogen compounds and other substances are transformed by chemical processes in the atmosphere and then deposited on earth in either wet or dry form. The wet forms, popularly called acid rain, can fall to earth as rain, snow, or fog. The dry forms are acidic gases or particulates.
Acid indigestion
Excessive secretion of hydrochloric acid by the stomach cells. Medically known as hyperchlorhydria. Sometimes used interchangeably with heartburn. See also: Heartburn.
Acid phosphatase
Acid phosphatase is an enzyme that works under acid conditions and is made in the liver, spleen, bone marrow and the prostate gland. Abnormally high serum levels of the enzyme may, for example, indicate prostate disease (infection, injury, or cancer).
Acid rain
Rain resulting from the combination of fossil fuel emissions and water in the atmosphere. The environmental effects of acid rain include the acidification of lakes and streams, damage to trees at high altitude, the acceleration of decay in buildings and poorer air quality. Acid rain also poses serious human health risks by contributing to heart and lung disorders such as asthma and bronchitis. Acid rain can be reduced by the regulation of industrial emissions and the adoption of energy efficiency alternatives and pollution prevention programs. Acid rain is a form of acid deposition.
Acid reflux
A common condition and an abnormal one in which acid in the stomach rises up into the esophagus. This occurs because the valve separating the contents of the stomach from the esophagus does not function properly. See also: GERD.
Acid, amino
One of the 20 building blocks of protein. The sequence of amino acids in a protein and, hence, the function of that protein are determined by the genetic code in the DNA. Amino acids are molecules that (in technical terms) contain a basic amino (NH2) group, an acidic carboxyl (COOH) group and a side chain attached to an alpha carbon atom. The 20 amino acids are alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, and valine.
Acid, fatty
"One of many molecules that are long chains of lipid-carboxylic acid found in fats and oils and in cell membranes as a component of phospholipids and glycolipids. (Carboxylic acid is an organic acid containing the functional group -COOH.) Fatty acids come from animal and vegetable fats and oils. Fatty acids play roles outside the body; they are used as lubricants, in cooking and food engineering, and in the production of soaps, detergents, and cosmetics. Related terms include the following: Essential fatty acid: An essential fatty acid is a polyunsaturated fatty acid needed by the body that is synthesized by plants but not by the human body and is therefore a dietary requirement. Free fatty acids: By-products of the metabolism of fat in adipose tissues. Omega-3 fatty acids: Omega-3 fatty acids are a class of fatty acids found in fish oils, especially in salmon and other cold-water fish, that lowers the levels of cholesterol and LDL (low-density lipoproteins) in the blood. (LDL cholesterol is the ""bad"" cholesterol.) Trans fatty acid:Trans fatty acids (trans fats) are made through hydrogenation to solidify liquid oils. They increase the shelf life of oils and are found in vegetable shortenings and in some margarines, crackers, cookies, and snack foods. Intake of trans fatty acids increases blood LDL-cholesterol (""bad"" cholesterol) levels and raises the risk of coronary heart disease."
Acid, nucleic
"One of the molecules in the chromosomes of living cells and viruses that plays a central role in the storage and replication of hereditary information and in the expression of this information through protein synthesis. The two chief types of nucleic acids are:
Acid, trans fatty
An unhealthy substance, also known as trans fat, made through the chemical process of hydrogenation of oils. Hydrogenation solidifies liquid oils and increases the shelf life and the flavor stability of oils and foods that contain them. Trans fat is found in vegetable shortenings and in some margarines, crackers, cookies, snack foods and other foods.
Acid-base balance
Acid-base balance refers to the mechanisms the body uses to keep its fluids close to neutral pH (that is, neither basic nor acidic) so that the body can function normally.
Acidophilus
"Bacteria found in yogurt that can help restore a supportive bacterial environment to an intestinal tract whose normal intestinal bacterial population (""flora"") has been disturbed by disease or antibiotics. Eating yogurt with acidophilus may also be useful in preventing candidiasis (thrush), including in the vagina."
Acidosis
An abnormal condition in the body in which excessive acid lowers the pH of the blood and body tissues.

Acinetobacter
(Pronounced AH-sin-neto-bacter). A group of bacteria found in soil, water, and hospitals where they can cause serious infections in immunocompromised people and are often resistant to antibiotics. Acinetobacter can be isolated from many sources including drinking and surface water, soil, sewage and different types of foods. At least a quarter of healthy people carry Acinetobacter harmlessly on their skin. But in hospitals some strains, particularly Acinetobacter baumannii, can cause infections including pneumonia and bacteremia (bloodstream infection). In technical terms, the Acinetobacter genus belongs to the gamma subdivision of Proteobacteria, and to the Moraxellaceae family.
Acinus, pulmonary
"The ending of a tiny airway in the lung, where the alveoli (air sacs) are located. In anatomy, an acinus is a round cluster of cells, usually epithelial cells, that looks somewhat like a knobby berry. The word ""acinus"" means ""berry"" in Latin. (The plural is ""acini"".) There are also acini, round clusters of epithelial cells, in the salivary glands and in the pancreas."
