应用

乙酰辅酶A是酶促的乙酰转移反应中酰基的必需辅助因子和载体。 可通过线粒体中丙酮酸的氧化脱羧、长链脂肪酸的氧化或某些特定氨基酸的氧化降解,可形成乙酰辅酶A。乙酰辅酶A是柠檬酸循环(克雷布氏循环)的起始化合物。 同时,它也是脂质生物合成的关键前体、所有脂肪酸碳的来源。 乙酰辅酶A可正向调节丙酮酸羧化酶的活性。 乙酰辅酶A是神经递质乙酰胆碱的前体。 组蛋白乙酰化酶(HAT)使用乙酰辅酶A作为乙酰基的供体,用于组蛋白和非组蛋白蛋白的翻译后乙酰化反应。

  5. What is the formula weight for the Product No. A2056, Acetyl Coenzyme A?

    The formula weight for the Product No. A2056, Acetyl Coenzyme A, as reported on the website is for the free base with a weight of 809.57 daltons.

  6. For Product No. A2056, Acetyl Coeznyme A, why is the formula weight listed on the website and the formula weight listed on the label different?

    The difference in the formula weights reported for Product No. A2056, Acetyl Coenzyme A, on the website versus the label is due to the sodium and water content of the product which may vary from lot to lot.  The formula weight of the free base is reported on the website, however on the label, variations in sodium and water content will reflect differences in formula weights reported on the label for a specific lot of product.

  7. What is the solution stability for the A2056, Acetyl Coenzyme A?

    The solution stability is reported as followed:  A solution of the product can be stored in neutral buffer or below (pH 3-7) for no longer than two weeks at -20°C when divided into aliquots. This is recommended for keeping the solution stable. It would be better to prepare fresh solutions and use soon after.

The αβ-tubulin subunits of microtubules can undergo a variety of evolutionarily-conserved post-translational modifications (PTMs) that provide functional specialization to subsets of cellular microtubules. Acetylation of α-tubulin residue Lysine-40 (K40) has been correlated with increased microtubule stability, intracellular transport, and ciliary

Lysine (K) acetylation refers to transfer of the acetyl moiety from acetyl-CoA to the ε-amino group of a lysine residue. This is posttranslational and reversible, with its level dynamically maintained by lysine acetyltransferases (KATs) and deacetylases (KDACs). Traditionally, eukaryotic KDACs

Histone posttranslational modifications and chromatin dynamics are inextricably linked to eukaryotic gene expression. Among the many modifications that have been characterized, histone tail acetylation is most strongly correlated with transcriptional activation. In Metazoa, promoters of transcriptionally active genes are generally
