另一种是在缠绕着DNA的蛋白质上添加稍大一些的乙酰基，于是便产生了相反的效果———使基因表达更容易了。

硫酸乙酰肝素是肝磷脂的前体，是重要的抗凝剂，目前只能从血液中提取，从未成功合成提取过，它并不是蛋白质，而是一种富硫似糖的分子，经常参与糖基化反应。
This is a precursor to heparin, an important anti-clotting agent that has, at present, to be extracted from blood, rather than being synthesised. Heparan sulphate is not a protein.
这两种酶是组蛋白乙酰转移酶(它能给蛋白质添加乙酰基)和甲基化dna结合蛋白- 2(它能把DNA上的甲基去除)。
The enzymes in question are histone acetyltransferase (which adds acetyl groups to proteins) and methylated DNA-binding protein-2 (which removes methyl groups from DNA).
鸡蛋等蛋白质丰富的食品中富含胆碱。胆碱是人体必需的营养素，因为它参与细胞膜的形成和神经递质乙酰胆碱的合成，而这些会影响记忆。
Choline, found in protein-rich food such as eggs, is needed by everyone for the production of cell membranes and for making the neurotransmitter acetylcholine, which affects memory.
硫酸乙酰肝素并不是一种蛋白质，在某种程度上它只是经常参于糖基化的一种富硫的、类糖的分子。
Heparan sulphate is not a protein. It is, rather, a sulphur-rich sugar-like molecule of a sort often involved in glycosylation.
是否应该是 缺少关爱的老鼠糖皮质激素受体基因和 基因周边的蛋白质表现出高水平的甲基化及较低水平的乙酰化。 另，acetylation 是否应该是乙醇化？
Rats that had experienced little maternal care showed high levels of methylation and low levels of acetylation of the glucocorticoid-receptor gene and its neighbouring proteins.
蕨菜嫩叶含胡萝卜素、维生素、蛋白质、脂肪、糖、粗纤维、钾、钙、镁、蕨素，蕨甙、乙酰蕨素、胆碱、甾醇此外还含有18种氨基酸等。

SITR 1是一种组蛋白脱乙酰基酶，一种能够阻断来自调节基因的转录因子的蛋白质。
SITR1 is a histone deacetylase, a protein that blocks transcription factors from regulating genes.
随着研究的深入，发现蛋白质乙酰化状态对细胞因子的分泌、NO的产生等方面均有较大的影响。
With in-depth study, we found that protein acetylation have great influence in the secretion of cytokines, generation of NO and so on.
