Amino Acid Sequence

Tyr-Gly-Gly-Phe-Leu

一般說明

亮氨酸脑啡肽是一种五肽,是中央和周围组织的正常成分。亮氨酸脑啡肽的氨基酸序列为 Tyr-Gly-Gly-Phe-Leu,分布在包括人在内的多种动物的大脑中。它是一种内源性阿片类神经递质/神经调节剂,位于大脑中和δ受体类似的位置。

應用

亮氨酸脑啡肽乙酸盐盐水合物已用于单级 TOF 模式下 Q-Tof Micro 混合,三重四极杆正交飞行时间(TOF)质谱仪的校准。它也已用于进行质谱的校准。它也已被用于液相色谱-质谱(LCMS)/ MS 中进行系统校准和光谱的相对校正。

生化/生理作用

亮氨酸脑啡肽(LEU-ENK)在 μ-和 δ-阿片受体位点均起激动剂的作用。它也可能在吗啡敏感的突触中充当神经递质。亮氨酸脑啡肽还与疼痛调节有关。骆驼泪神经中表达的 LEU-ENK 调节泪液和蛋白质分泌。LEU-ENK 在代谢过程中会被多种酶降解,包括氨基肽酶 N(APN)、中性内肽酶(NEP)、二肽基肽酶 3(DPP3)、羧基肽酶 A6(CP​​A-6)和血管紧张素转换酶(ACE),有时也称为脑啡肽酶。
