一般描述

D -丝氨酸是一种右旋氨基酸,存在于神经元、星形胶质细胞和小胶质细胞中。由丝氨酸消旋酶从 L -丝氨酸合成。消旋酶也可催化 D -丝氨酸分解成氨和丙酮酸。它可被 D -氨基酸氧化酶氧化为羟基丙酮酸。
D-丝氨酸是一种在哺乳动物大脑中表达的特殊氨基酸。

应用

D -丝氨酸已被用作人 1321N1 星形细胞瘤细胞中 D -氨基酸氧化酶 (DAO) 活性的底物。它还被用于大鼠脑室内给药以诱导抗伤害刺激效应。
D-丝氨酸已被用于防止 N-甲基 D-天冬氨酸受体 (NMDAR) 的甘氨酸依赖性脱敏,并研究了其对 NMDARs 的作用,以纠正部分坐骨神经结扎 (PSNL) 后大鼠的行为异常。

生化/生理作用

D -丝氨酸对于树突的正常发育、成神经细胞迁移是必需的,并且可能具有精神分裂症和抑郁症治疗潜力。在创伤性脑损伤 (TBI) 中 D -丝氨酸水平升高。
D-丝氨酸是激动剂和甘氨酸模拟物,在番木鳖不敏感的甘氨酸结合位点有活性,这类结合位点与 N-甲基-D-天门冬氨酸(NMDA)受体相关,也与抑制性突触后甘氨酸受体相关。它与谷氨酸一起,在各种生理过程中起作用,这些过程包括突触可塑性和受体传递。D-丝氨酸信号传导失调与神经退行性疾病和神经失调相关。

  1. How does the storage temperature relate to shipping conditions?

    The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. See Shipping and Storage for more information.
