一般說明

蔗糖是一种由葡萄糖和果糖组成的双糖,在各种生物过程中是能量来源。在细胞培养中,蔗糖作为冷冻保护剂,在冷冻和解冻过程中保持细胞活力,同时也有助于维持渗透平衡,提高细胞存活率。此外,蔗糖在植物、昆虫和细菌培养基中作为补充物,并应用于各种酶分析。在生物医学研究中,它作为渗透物、藻类代谢物、酿酒酵母代谢物、大肠杆菌代谢物和小鼠代谢物发挥作用。

應用

蔗糖已被用作
  • 一种生长培养基,用于研究植物与病原体相互作用和植物免疫反应的分子和生化方面
  • 作为冷冻保护剂,用于涉及抗生素引起的肠道微生物群变化及其对神经免疫相互作用影响的研究

生化/生理作用

蔗糖是重要的能量来源,通过代谢转化产生三磷酸腺苷 (ATP),以用于细胞功能和细胞呼吸。在植物生物学中,蔗糖是光合作用的核心,在植物的各个部分储存碳水化合物。在细胞生物学中,它有助于维持细胞内的渗透平衡,在实验室环境中充当冷冻保护剂,并参与生物合成,导致次生代谢物的形成。

特點和優勢

  • 适用于细胞生物学和生物化学研究
  • 经过测试,确认低水平的重金属污染,确保各种应用的适用性
  • 经过测试,检测阴离子和阳离子的痕迹
  • ACS 级蔗糖,来源于甘蔗
