一般描述
肽聚糖。是一种生物聚合物，是革兰氏阳性菌细胞壁的主要成分。肽聚糖由 N -乙酰基葡糖胺和 N -乙酰基胞壁酸交替单位的碳水化合物骨架组成，并被 D -和 L -氨基酸修饰。 N -乙酰胞壁酸残基与寡肽交联。末端肽为 D -丙氨酸，但其他氨基酸以 D -异构体存在。
应用
肽聚糖可用于裂解酶（如裂解酶）的活性评估。建议使用浓度为 0.15-3μ 的肽聚糖g/ml，溶于水或缓冲液，在 450 nm 处测定。肽聚糖不溶解，但在水中产生混悬液。
肽聚糖可激活 Toll 样受体 2 (TLR2)，TLR2 存在于哺乳动物细胞中以刺激淋巴细胞。也可作为 Poly (I:C) 的拮抗剂发挥作用。

What is the molecular weight of Product 69554, Peptidoglycan?
1 answer-
Unfortunately, we have no references reporting the molecular weight of peptidoglycan. Because it is not soluble without destroying the original structure, the molecular weight can not be determined by suitable analytical methods (GPC, viscosity, light scattering).
