L-谷氨酸 (L-Glutamic acid)分子量为147.13,分子式为C₅H₉NO₄,CAS号为56-86-0,是一种酸性氨基酸。分子内含两个羧基,化学名称为α-氨基戊二酸。谷氨酸是里索逊1856年发现的,为无色晶体,有鲜味,微溶于冷水,易溶于热水,可溶于盐酸溶液,等电点3.22。谷氨酸大量存在于谷类蛋白质中,动物脑中含量也较多,在生物体内的蛋白质代谢过程中占重要地位,参与动物、植物和微生物中的许多重要化学反应。谷氨酸是生产味精、香料的原料,亦可用作哺乳动物细胞培养中培养基的添加剂,用途极为广泛。
L-谷氨酸溶液 (0.1 mol/L)主要由L-谷氨酸、去离子水组成,经过滤除菌处理。该试剂仅用于科研领域,不适用于临床诊断或其他用途。
操作步骤 (仅供参考):
1、按实验具体要求操作。
2、一般按培养基: L-谷氨酸溶液=100: 1使用。
注意事项:
1、注意避免反复冻融,并且注意无菌操作。
2、试剂开封后请尽快使用,以防影响后续实验效果。
3、为了您的安全和健康,请穿实验服并戴一次性手套操作。
L-Glutamic acid has a molecular weight of 147.13, a molecular formula of and a CAS number of 56-86-0. It is an acidic amino acid with two carboxyl groups in its molecule, and its chemical name is α-aminoglutaric acid. Discovered by Ritthausen in 1856, L-glutamic acid appears as colorless crystals with a savory taste. It is slightly soluble in cold water, readily soluble in hot water, and soluble in hydrochloric acid solution, with an isoelectric point of 3.22.
L-glutamic acid is abundant in cereal proteins and also present in high concentrations in animal brains. It plays a crucial role in protein metabolism in organisms and participates in numerous important chemical reactions in animals, plants and microorganisms. It serves as a raw material for the production of monosodium glutamate (MSG) and fragrances, and can also be used as an additive in culture media for mammalian cell culture, boasting extremely extensive applications.
The L-Glutamic Acid Solution (0.1 mol/L) is mainly composed of L-glutamic acid and deionized water, and undergoes filtration sterilization. This reagent is for research use only (RUO) and is not suitable for clinical diagnosis or any other purposes.
Operating Procedures (For Reference Only)
1. Operate in accordance with the specific requirements of the experiment.
2. Generally, it is used at a ratio of culture medium: L-glutamic acid solution=100:1.
Precautions
1. Avoid repeated freeze-thaw cycles and ensure sterile operation.
2. Please use the reagent as soon as possible after opening to prevent affecting subsequent experimental results.
3. For your safety and health, wear a lab coat and disposable gloves during operation.
