General description
N-羟乙酰神经氨酸(Neu5Gc) 是一种非人类唾液酸分子,可在猪中而不是人类中合成,作为哺乳动物代谢产物和抗原起一定作用。这种唾液酸,特别是N-乙酰神经氨酸的羟基化形式,在氮原子上有羟乙酰取代基,在异头物中心(anomeric center)有β-构型。N-羟乙酰神经氨酸的生物合成涉及胞苷一磷酸-N-乙酰神经氨酸(CMP-Neu5Ac)羟化酶的酶活性。
在人体内,内源性生产的缺乏是影响CMP-Neu5Ac羟化酶的基因突变的结果,该羟化酶可将N-羟乙酰神经氨酸转化为Neu5Gc。但是,通过膳食(如红肉和乳制品)从外部摄取,Neu5Gc可在人体细胞中积累。N-羟乙酰神经氨酸是一种多功能化合物,可应用于细胞生物学、代谢组学和生物化学研究。

Application
N-羟乙酰神经氨酸已被用于:
- 作为微量滴定生物膜(microtiter biofilm )方法中的糖用于改善生物膜形成
- 作为标准品用于测定量蚕神经系统中的唾液酸,并用于发现不同发育阶段唾液酸的变化
- 作为高效液相色谱(HPLC)分析中的标准品用于以1,2-二氨基-4,5-亚甲基二氧苯(DMB)为荧光化合物检测唾液酸(Sia)分子
Biochem/physiol Actions
N-羟乙酰神经氨酸(Neu5Gc)是分析抗-Neu5Gc抗体和唾液酸结合蛋白的重要工具。

Influenza viruses of gallinaceous poultry and wild aquatic birds usually have distinguishable receptor-binding properties. Here we used a panel of synthetic sialylglycopolymers and solid-phase receptor-binding assays to characterize receptor-binding profiles of about 70 H7 influenza viruses isolated from aquatic birds

Feline panleukopenia virus (FPV) is a pathogen whose canine-adapted form (canine parvovirus (CPV)) emerged in 1978. These viruses infect by binding host transferrin receptor type-1 (TfR), but also hemagglutinate erythrocytes. We show that hemagglutination involves selective recognition of the non-human

N-glycolylneuraminic acid (Neu5Gc) is an immunogenic sugar of dietary origin that metabolically incorporates into diverse native glycoconjugates in humans. Anti-Neu5Gc antibodies are detected in all human sera, though with variable levels and epitope-recognition profiles. These antibodies likely play a role
