体外研究 (In Vitro) |
曾经被认为是收缩骨骼肌缺氧的结果,糖酵解产物乳酸在完全有氧条件下形成和持续利用。“细胞-细胞”和“细胞内乳酸穿梭”的概念描述了乳酸在氧化和糖异生底物的传递以及细胞信号传导中的作用。细胞-细胞穿梭的例子包括乳酸交换(i)在工作肌肉床内白色糖酵解纤维和红色氧化纤维之间;(ii)在工作的骨骼肌和心脏之间;(3)组织间乳酸净释放与糖异生。乳酸穿梭存在于包括大脑在内的多种组织中,其中星形胶质细胞和神经元之间的穿梭与谷氨酸能信号传导有关。由于糖原分解和糖酵解的产物乳酸是通过氧化代谢处理的,因此乳酸穿梭将细胞能量转导的两个主要过程结合起来。乳酸的处理主要是通过氧化,特别是在运动时,氧化占了70-75%的去除和剩余的糖异生。乳酸通量沿着由线粒体乳酸氧化复合物建立的质子和浓度梯度发生。马拉松赛跑是一项需要高糖酵解和氧化通量的体力活动;这样的活动需要乳酸穿梭。关于乳酸穿梭的知识还没有被传授给这项运动。[1]

Absorption, Distribution and Excretion
In order to be absorbed, calcium must be in its freely soluble form (Ca2+) or bound to a soluble organic molecule. Calcium absorption mainly occurs at the duodenum and proximal jejunum due to more acidic pH and the abundance of the calcium binding proteins. The mean calcium absorption is about 25% of calcium intake (range is 10 – 40%) in the small intestine, and is mediated by both passive diffusion and active transport. Following oral administration to a human volunteer, 20 to 30% of a dose of lactic acid of up to 3000 mg was excreted via the urine during a period of 14 hours. The majority of calcium absorbed (99%) is stored in the skeleton and teeth for structural integrity. No pharmacokinetic data available. Metabolism / Metabolites In hepatic gluconeogenesis, lactic acid is converted to glucose. Lactic acid may be further catabolyzed in the lactic acid cycle.

其他信息 |
Calcium lactate is a salt that consists of two lactate anions for each calcium cation (Ca2+). It is prepared commercially by the neutralization of lactic acid with calcium carbonate or calcium hydroxide. Approved by the FDA as a direct food substance affirmed as generally recognized as safe, calcium lactate is used as a firming agent, flavoring agent, leavening agent, stabilizer, and thickener. Calcium lactate is also found in daily dietary supplements as a source of calcium. It is also available in various hydrate forms, where calcium lactate pentahydrate is the most common.
Drug Indication Indicated for use as the nutritional supplement. Mechanism of Action In aqueous environments such as the gastrointestinal (GI) tract, calcium lactate will dissociate into calcium cation and lactic acid anions, the conjugate base of lactic acid. Lactic acid is a naturally-occurring compound that serves as fuel or energy in mammals by acting as an ubiquitous intermediate in the metabolic pathways. Lactic acid diffuses through the muscles and is transported to the liver by the bloodstream to participate in gluconeogenesis. |

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;
2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;
3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);
4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。
计算结果:
工作液浓度: mg/mL;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。
