Glycogen is a polysaccharide which serves as a form of energy storage in animals and fungi [1]. It is mainly found in the liver and muscle tissues as a secondary long-term energy storage molecule[2]. Glycogen is well-studied in research on cellular metabolism[3], diabetes[4], and athletic performance[5]. In addition, Glycogen is also used as a carrier to help the precipitation and recovery of small amounts of DNA and RNA during nucleic acid extraction, improving the yield and purity of the extracted nucleic acids[6][7].

Glycogen (糖原)是一种多糖,在动物和细菌中作为重要的能量储存分子[1]。它主要存在于肝脏和肌肉组织中,起到次级长期能量储存分子的作用[2]。糖原在细胞代谢[3]、糖尿病[4]和运动表现[5]等领域中被广泛研究。此外,糖原还被用作载体,帮助在核酸提取过程中沉淀和回收少量的DNA和RNA,从而提高提取核酸的产量和纯度[6][7]。
