产品说明

一般描述

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards. Palmitic acid is the main constituent of human milk fatty acids. It is also found in acerola fruit, sea weeds and air-dried fruit of Cornus officinalis.

应用

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.

分析说明

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP primary standards, where they are available.

其他说明

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

生化/生理作用

棕榈酸是一种直链16碳脂肪酸。 富含棕榈酸以及月桂酸和肉豆蔻酸的饮食，与血清中低密度脂蛋白胆固醇水平升高有关。 棕榈酸是脂肪生成过程产生的第一种脂肪酸。 它是乙酰辅酶A羧化酶(ACC)的负调节因子，与脂肪酸诱导的胰岛素抵抗有关。
棕榈酸(PA)是膜磷脂(PL)和脂肪三酰基甘油(TAG)的成分。棕榈酸水平升高促进动脉粥样硬化、2型糖尿病、神经退行性疾病、肥胖和癌症的病理生理发展。PA通过调节p38丝裂原活化蛋白激酶(MAPK)途径促进内皮细胞的凋亡，并有利于TNF-α的表达和活性氧的积累。PA促进肝细胞中的白细胞介素8(IL-8)合成，导致肝炎。PA通过与toll样受体4(TLR4)的相互作用，诱导心肌细胞的炎性损伤。
