  • derivatives
  • Several widely used examples of these aldehydes are obtained as natural derivatives, with benzaldehyde being derived from almonds, cinnamaldehyde from cinnamon, and carvone from caraway seeds as a spearmint flavor. (wisegeek.com)
  • chiral
  • To date, all practical methods for the preparation of chiral a-sulfenylated aldehydes have been multistep procedures that involve chiral auxiliaries. (docme.ru)
  • Asymmetric Catalysis Enantioselective Organocatalyzed a Sulfenylation of Aldehydes** Mauro Marigo, Tobias C. Wabnitz, Doris Fielenbach, and Karl Anker Jørgensen* Optically active a-heterosubstituted aldehydes are versatile building blocks for the synthesis of chiral molecules that bear heteroatom functionalities. (docme.ru)
  • compounds
  • This toxicological profile focuses on endrin, but because of its close association to both endrin aldehyde and endrin ketone, the profile includes studies with data relevant to human exposure to these compounds when available. (cdc.gov)
  • Aldehyde oxidase is very concentrated in the liver, where it oxidizes multiple aldehydes and nitrogenous heterocyclic compounds, such as anti-cancer and immunosuppressive drugs. (wikipedia.org)
  • The fatty aldehydes include compounds such as octanal, nonanal, decanal or dodecanal. (wikipedia.org)
  • molecule
  • Aldehydes have properties that are diverse and that depend on the remainder of the molecule. (wikipedia.org)
  • The active site binds to one molecule of an aldehyde and an NAD(P)+ that functions as a cofactor. (wikipedia.org)
  • Cyclamen aldehyde is a fragrance molecule which has been used in soaps, detergents, lotions and perfumes since the 1920s. (wikipedia.org)
  • anion
  • The anionic species formally derived from deprotonation of an aldehyde proton, known as an acyl anion, is highly unstable and must be kept at low temperatures. (wikipedia.org)
  • The Vanderwal group has also reported the synthesis of 4-stannyldienals from Zincke aldehydes by addition of tributylstannyl anion and quenching with acetyl chloride. (wikipedia.org)
  • carbonyl
  • A carbonyl group is introduced into proteins as a chemical reporter using different techniques, including modern methods like stop codon suppression and the herein discussed aldehyde tag. (wikipedia.org)
  • group
  • Related to (i), the aldehyde group is somewhat polar . (wikipedia.org)
  • If the presence of another functional group demands the use of a suffix, the aldehyde group is named with the prefix formyl- . (wikipedia.org)
  • To provide for facile product elaboration, S-benzyl-protected a-sulfenylated aldehydes were chosen as synthetic targets, as there are well-established methods for the cleavage of this protecting group. (docme.ru)
  • In 2009, the Vanderwal group reported another interesting rearrangement of Zincke aldehydes. (wikipedia.org)
  • The nomenclature is derived from the nomenclature of the alkanes, the ending -al is added to indicate the aldehyde group. (wikipedia.org)
  • Polyunsaturated aldehydes (PUAs) are a group of allelopathic chemicals typically associated with diatom-copepod predator-prey interactions. (wikipedia.org)
  • The aldehyde tag is a short peptide tag which can be introduced into fusion proteins and by subsequent treatment with the formylglycine-generating enzyme (FGE) a reactive aldehyde group is generated for further coupling. (wikipedia.org)
  • This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with NAD+ or NADP+ as acceptor. (wikipedia.org)

  • species
  • Aldehyde oxidase is a member of the molybd-flavo protein family and has a very complex evolutionary profile-as the genes of AO varies according to animal species. (wikipedia.org)
  • Thalassiosira rotula represents the most well-studied diatom species in terms of polyunsaturated aldehyde production. (wikipedia.org)
  • form
  • Endrin may also be broken down by exposure to high temperatures (230�C) or light to form primarily endrin ketone and endrin aldehyde. (cdc.gov)
  • known
  • This map displays locations where Endrin (Endrin aldehyde) is known to be present. (cdc.gov)
  • Little is known about the properties of endrin aldehyde, an impurity and breakdown product of endrin, or endrin ketone, which is a product of endrin when it is exposed to light. (cdc.gov)
  • addition
  • Upon addition of a N,N-disubstituted formamide (such as DMF) a hemiaminal is formed, which can easily be hydrolyzed into the desired aldehyde. (wikipedia.org)
