calcium absorption

Glutamyl-glutamic acid (Glu-glu) 是一些微球菌和节杆菌属菌的胞壁中的肽桥。

L-Threonic acid Calcium Salt 是一种抗骨质疏松症，能够刺激抗坏血酸的吸收，常用于钙补充剂。

L-Lysine hydrochloride 是一种人类必需氨基酸，能增加钙吸收，减少糖尿病相关疾病和改善肠道健康，可用于疱疹的研究。

Calcitriol (1,25-Dihydroxyvitamin D3) 是一种维他命 D 的代谢物，一种维他命 D 受体 (VDR) 的激动剂 (IC50=0.4 nM)。Calcitriol 增加肠道对钙和磷的吸收，并与甲状旁腺激素一起增加了骨吸收。

Urotensin II is a peptide vasoconstrictor and agonist of the urotensin (UT) receptor (Ki= 2.06 nM for the human recombinant receptor expressed in HEK293 cells).1It stimulates intracellular calcium mobilization in HEK293 cells expressing human and rat UT (EC50s = 0.47 and 0.78 nM, respectively) but decreases intracellular calcium concentration in goby (G. mirabilis) enterocytes when used at a concentration of 500 nM.2Urotensin II (20 mU/ml) stimulates active sodium and chloride absorption across isolated goby posterior intestine in 5% seawater-adapted solution.3In vivo, urotensin II (1.5-150 nmol/kg) decreases diastolic blood pressure and increases heart rate in anesthetized rats.4It also reduces the pressor responses to sympathetic nerve stimulation, norepinephrine , and vasopressin in pithed rats when administered at a dose of 150 nmol/kg. 1.Ames, R.S., Sarau, H.M., Chambers, J.K., et al.Human urotensin-II is a potent vasoconstrictor and agonist for the orphan receptor GPR14Nature401(6750)282-286(1999) 2.Loretz, C.A., and Assad, J.A.Urotensin II lowers cytoplasmic free calcium concentration in goby enterocytes: Measurements using quin2Gen.

pTH-Related Protein (1-40) (human, mouse, rat) 促进大鼠肠细胞通过PTHR1受体和PKCα β信号通路的钙吸收作用。该蛋白增加了甲状旁腺激素1受体（PTHR1）表达，提升了四种跨膜钙转运蛋白—TRPV6、CaBP-D9k、NCX1和PMCA1的水平。

(+)-Bornyl acetate 存在于 Pichtae 精油 (西伯利亚冷杉针油) 中。它能够显著抑制拟南芥幼苗根系生长。

1α,25-Dihydroxyprevitamin D3，作为维生素 D3 (VD3) 的最有效的生物活性形式，主要用于调节钙的吸收。

L-Lysine-4,4,5,5-d4 Hydrochloride 是 L-Lysine Hydrochloride 的氘代化合物。L-Lysine Hydrochloride 的 CAS 号为 657-27-2。L-lysine hydrochloride 是一种人类必需氨基酸，能增加钙吸收，减少糖尿病相关疾病和改善肠道健康，可用于疱疹的研究。
