丁二酮 - 维基百科，自由的百科全书
网页丁二酮是发酵合成 缬氨酸 的副产物。 在合成过程中酵母产生的 α-乙酰乳酸 从细胞内放出并自发脱羧生成丁二酮，酵母重新吸收丁二酮并还原其羰基生成无味的 3-羟基-2-丁酮 与 2,3-丁二醇。 啤酒生产有时会有“丁二酮休息”，即发酵完成后两三天略微提高温度，以使酵母能吸收先前发酵历程中生成的丁二酮。 有的葡萄酒生产商，如 霞多丽，为了其口感有意促进丁二酮的生成。 霞多丽 葡萄酒中丁二酮浓度为0.005毫克／升到1.7毫克／升的测量，0.2毫 …

Deacetylase Enzymes: Chemistry & Biology - Cell Press
网页Introduction. The reversible acetylation of histones plays a critical role in transcriptional regulation in eukaryotic cells, and there is mounting evidence that acetylation of non-histone substrates is important for other cellular processes (reviewed in [1]). Two families of deacetylase enzymes have been identified: the histone deacetylases ...
