Backward Glossary Phytochemicals B!

Glossary Online Glossary edited with meticulous attitude and published as convenience for site content reference,including glossaries of related different topics,Glossary Phytochemicals are dedicated to Phytochemicals and phyto derived chemical components.Phytochemicals have been used as drugs for millennia. Hippocrates may have prescribed willow tree leaves to abate fever. Salicin, having anti-inflammatory and pain-relieving properties, was originally extracted from the white willow tree and later synthetically produced become the staple over-the-counter drug called Aspirin!

 Glossary Phytochemicals Icon01
 Phytochemicals are chemical compounds such as beta-carotene that occur naturally in plants. The term is generally used to refer to those chemicals that may affect health, but are not yet established as essential nutrients.While there is abundant scientific and government support for recommending diets rich in fruits and vegetables, there is only limited evidence that health benefits are due to specific phytochemicals.

 Glossary Phytochemicals Icon02
 There is evidence from laboratory studies that phytochemicals in fruits and vegetables may reduce the risk of cancer, possibly due to dietary fibers, polyphenol antioxidants and anti-inflammatory effects. Specific phytochemicals, such as fermentable dietary fibers, are allowed limited health claims by the US Food and Drug Administration (FDA).

 Biotin Biotin
 Biotin:[58-85-5]Biotin is a water-soluble vitamin, generally classified as a B-complex vitamin. After the initial discovery of biotin, nearly forty years of research were required to establish it as a vitamin. Biotin is required by all organisms but can only be synthesized by bacteria, yeasts, molds, algae, and some plant species.
Synonyms:(+)-Biotin; 1H-Thieno[3,4-d]imidazole-4-pentanoic acid, hexahydro-2-oxo-, [3aS-(3aalpha,4beta,6aalpha)]-; Biotin; Biotin (Pure and Triturations); D-Biotin; Hexahydro-2-oxo-1H-thieno[3,4-d]imidazole-4-pentanoic acid; Vitamin B7; Vitamin H;
CAS Type 1 Name:1H-Thieno(3,4-d)imidazole-4-pentanoic acid, hexahydro-2-oxo-, (3aS-(3aalpha,4beta,6aalpha))-  Vitamin H
Formula:C10H16N2O3S.  CAS RN:58-85-5 Other RN:3672-05-7  M.W.:244.308  
Note:A water-soluble, enzyme co-factor present in minute amounts in every living cell. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk. Hexahydro-2-oxo-1H-thieno(3,4-d)imidazole-4-pentanoic acid. Growth factor present in minute amounts in every living cell. It occurs mainly bound to proteins or polypeptides and is abundant in liver, kidney, pancreas, yeast, and milk.The biotin content of cancerous tissue is higher than that of normal tissue.
 Biotin function:In its physiologically active form biotin is attached at the active site of four important enzymes, known as carboxylases. Each carboxylase catalyzes an essential metabolic reaction.
Acetyl-CoA carboxylase catalyzes the binding of bicarbonate to acetyl-CoA to form malonyl-CoA. Malonyl-CoA is required for the synthesis of fatty acids.
Pyruvate carboxylase is a critical enzyme in gluconeogenesis, the formation of glucose from sources other than carbohydrates, for example, amino acids and fats.
Methylcrotonyl-CoA carboxylase catalyzes an essential step in the metabolism of leucine, an indispensable (essential) amino acid.
Propionyl-CoA carboxylase catalyzes essential steps in the metabolism of amino acids, cholesterol, and odd chain fatty acids (fatty acids with an odd number of carbon molecules).
Histones are proteins that bind to DNA and package it into compact structures to form chromosomes. The compact packaging of DNA must be relaxed somewhat for DNA replication and transcription to occur. Modification of histones through the attachment of acetyl or methyl groups (acetylation or methylation) has been shown to affect the structure of histones, thereby affecting replication and transcription of DNA. The attachment of biotin to another molecule, such as a protein, is known as "biotinylation". The enzyme biotinidase has recently been shown to catalyze the biotinylation of histones, suggesting that biotin may play a role in DNA replication and transcription.
 Biotransformation enzymes (phase I and phase II):enzymes involved in the metabolism and elimination of a variety of exogenous (drugs, toxins and carcinogens) and endogenous compounds (steroid hormones). In general, phase I biotransformation enzymes, including those of the cytochrome P450 family, catalyze reactions that increase the reactivity of fat-soluble compounds and prepare them for reactions catalyzed by phase II biotransformation enzymes. Reactions catalyzed by phase II enzymes generally increase water solubility and promote the elimination of these compounds.
 bipartite:divided, nearly to the base, into two parts, cf. bifid.
 bipinnate:of compound leaves, twice pinnately divided, cf. pinnate.
 biradial(of symmetry):= bisymmetric.

 buzz pollination:a variant of mellitophily where the bee vibrates a pendulous flower (its own wing muscles vibrate) causing the pollen to fall out of the anthers, the bee then collecting it; the flowers are polysymmetrical, the anthers often form a cone, and the petals are also reflexed, i.e. a very different floral morphology from that of many bee-pollinated flowers.
