唾液酸(SA)学名为N-乙酰基神经氨酸,通常以低聚糖、糖脂或糖蛋白形式存在;是细胞膜表面糖蛋白和糖酯的重要组成部分,广泛存在于动物细胞膜、血清糖蛋白以及哺乳动物的黏液腺中。作为一种细胞因子的辅助受体,其参与机体的多种重要生理过程,如与细胞膜和血管通透性有关,而且在炎症性疾病及恶性肿瘤病时增高,当微血管出现广泛损伤时,可表现有血管通透性增加及血清唾液酸浓度增高。因此,唾液
Sialic acid (SA) known as N-acetyl neuraminic acid, usually in the form of oligosaccharides, glycolipids or glycoproteins; is an important part of the cell membrane glycoproteins and sugar esters, widely present in animal membranes, serum Glycoproteins, and mucus glands in mammals. As a cytokine co-receptor, its participation in a variety of important physiological processes, such as the cell membrane and vascular permeability, but also in inflammatory diseases and malignant tumors increased, when the extensive damage of microvascular can be The performance of vascular permeability and serum sialic acid concentration increased. So saliva
