体外研究
(In Vitro)

各种 d-氨基酸,如 D-丝氨酸、D-天冬氨酸 (D-Asp) 和 D-Glutamic acid 广泛存在于包括人类在内的哺乳动物中,现在被认为是新的生理活性物质和/或生物标志物[1]
D-[Asp/Glu] (4 mg/mL) 抑制 IgE 与花生的结合 (75%),而 D-Glutamic acid、D-Asp 没有抑制作用。IgE 对 D-[Asp/Glu]具有特异性,可能具有去除 IgE 或减少 IgE 与花生过敏原结合的潜力[2]

体内研究
(In Vivo)

D-Glutamic acid 目前作为神经元传递和激素分泌的调节剂受到关注。它在哺乳动物中仅被 D-天冬氨酸氧化酶代谢[1]
腹膜内注射后,L-谷氨酸通过 a-酮戊二酸分解代谢,而 D-谷氨酸转化为 n-吡咯烷酮羧酸。D-和 L-谷氨酸的碳2在盲肠中转化为乙酸的甲基碳。大鼠肝脏和肾脏均催化 D-Glutamic acid 转化为正吡咯烷酮羧酸[3]

参考文献
Animal Administration
[3]

Rats: Male albino rats are given injections of L- or D-glutamic acid-2-C14, DL-glutamic acid-5-C14, or D-glutamic acid-5-C14. Injections by stomach tube or into the cecum are performed while the animals are under ether anesthesia. After the rats are killed, the “carcass” and liver glutamic acids are isolated, degraded, and assayed for radioactivity. “Carcass” refers to the entire animal, except liver, including the ished gastrointestinal tract[3].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
