g-glu-glu

L-γ-Glutamyl-L-glutamic acid是一种内源性γ-谷氨酰二肽，由两个 L-谷氨酸残基通过γ-谷氨酰键连接而成，参与谷氨酰循环(γ-glutamyl cycle)，常用于氨基酸代谢及相关生化机制研究。

G-Glu-Ser is a calcium receptor activator and Flavor-enriching agent.

γ-Glutamylvaline作为钙敏感受体(CaSR)的激活剂，具备抗炎生物学活性，可抑制 TNF-α 介导的促炎细胞因子合成，并上调 Wnt5a 的表达水平，通过激活 3T3-L1 小鼠脂肪细胞内的 CaSR 信号通路，从而改善慢性低度炎症状态。

Bz-IEGR-pNA is a colorimetric substrate for Factor Xa.1 Factor Xa preferentially binds to and cleaves the Ile-Glu-Gly-Arg (IEGR) peptide sequence to release p-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of Factor Xa activity.References1.

Rhodopsin peptide is a peptide with the sequence H2N-Val-Ser-Lys-Thr-Glu-Thr-Ser-Gln-Val-Ala-Pro-Ala-OH, MW= 1217.33. Rhodopsin is a biological pigment in photoreceptor cells of the retina that is responsible for the first events in the perception of ligh

Rac GTPase fragment is a peptide with the sequence H2N-Val-Phe-Asp-Glu-Ala-Ile-Arg-Ala-Val-OH, MW= 1019.15. Rac is a subfamily of the Rho family of GTPases, small signaling G proteins (more specifically a GTPase).
