醛類和酮類
英文
aldehydes & ketones-
The reaction of sulfate with aldehydes and ketones has been known for many years.
大家知道硫酸鹽能與醛類和酮類反應已有許多年了。By using sterically hindered, electron - rich alkylphosphines and n - heterocyclic carbenes ( nhc ), this process has encompassed a broad range of substrates including ketones, aldehydes, esters, amides, malonates, nitrocompounds, nitriles and sulfones
隨著大位阻、富電子烷基膦和氮雜環卡賓( nhc )為配體的催化體系的出現,該類反應的底物已從酮擴展到醛、酯、酰胺以及含酸性氫的化合物如丙二酸酯、硝基化合物、腈、碸等。Reactive aldehydes from lipid peroxidation such as malonaldehyde ( mda ), 4 - hydroxynonenal ( hne ) are responsible for the modification of different biological macromolecular structures and functions by reacting with either sh - groups or amino groups of bio - molecules to form seminercaptals or schiff bases and lead to various aging - related alterations
而我們則進一步提出這些不飽和的醛酮尤其是丙二醛( mda )與4 -羥基壬烯醛( hne )很可能是導致與疾病及衰老相關的老年色素類熒光物質的形成及血液粘度增加的內在原因之一。The expression vector prep9 was employed for the effective expression of ugt1a9 in chinese hamster lung cells ( chl ). the cell lines established were used for the study of glucuronidation in vitro, and the drug metabolism characteristics were summarized. as has been indicated that ugt1a9 mainly glucuronide hydroxyl, compounds that have aliphatic or phenol hydroxyl were selected for substrates of ugt1a9
由於botiag主要催化羥基的們醛釀綴合反應,本實驗選擇具有不同結構類型的含羥基化合物作為底物,一類是羥基處于芳環的異丙酚和撲熱息痛,其中異丙酚是gylag的專屬性底物,可以作為活性比較的參照,另一類是羥基處于脂鏈的普莢訖爾和普羅帕酮Auto data processing by tofms software combined with “ structured chromatogram ” was used to assign the components. 250 phenols were tentatively idenitified including 66 alkylphenol derivatives, 47 alkenylphenlo derivatives, 57 naphthalenol derivatives, 17 phenylphenol derivatives, 32 methoxyphenol derivatives, 9 acylphenol derivatives and 15 hydroxybenzaldehyde deriviatives
這些酚類化合物包括66個烷基苯酚、 47個烯基苯酚、 57個萘酚、 17個苯基苯酚、 32個甲氧基苯酚、 9個酚酮和15個酚醛化合物。Standard test method for purity of aldehydes and ketones
醛類和酮類純度的標準測試方法Propofol and paracetamol are compounds that have phenol hydroxyl and propranolol and propafenone are those that have aliphatic ones. among the four compounds, propofol is the specific substrate of ugt1a9 and can be served as the comparison reference of enzymatic activity. based on the study of four compound, four kinds of isoflavone compounds, i. e., quercetin, kaempferol, isorhamnetin and
在上述四種化合物研究的基礎上,考用類黃酮化合物對叭xs有各種影響,並且具有各種酚羥基結構,本實驗選擇了四種類黃酮化合物即們皮素、山費酚、異鼠辛素和蘆丁作為底物,觀察ix ; 1 』 iag對它們代謝的作用情況,試圖了解ijgtiag在這些化合物的葡醛酸代謝過程中所起的作用。分享友人
