一般描述

硼酸是一种弱单碱基路易斯酸(电子对受体),与醇发生可逆反应。因为具有温和的抗菌和抗真菌作用,它被用于皮肤和妇女卫生产品。硼酸在眼科产品中用作缓冲剂。分子结构使它成为一种高效的固体润滑剂。硼酸可用于玻璃制造、阻燃剂和肥料。硼酸在生物化学中用作缓冲溶液。它也在溶液中形成复杂的平衡,以四硼酸离子(B4O7 2-)为优势种。硼酸缓冲液涉及不连续电泳和毛细管电泳系统分离蛋白质和核酸。

应用

用于促进催化量的羧酸与胺的酰胺化反应。该技术无需羧酸预活化或使用偶联剂。
增强型共沸蒸馏:用于优化直接酰胺化反应的策略
硼酸已用于:
  • 制备硼酸缓冲液,用于纳米胶囊表面伯胺的定量测定
  • 研究其对表观遗传变化的影响
  • 使用凯氏定氮法测定小麦草中的蛋白质含量

特点和优势

  • 环保
  • 无毒性

Aberrant redox signaling underlies the pathophysiology of many chronic metabolic diseases, including type 2 diabetes (T2D). Methodologies aimed at rebalancing systemic redox homeostasis have had limited success. A noninvasive, sustained approach would enable the long-term control of redox signaling for

Boron, an essential micronutrient, is transported in roots of Arabidopsis thaliana mainly by two different types of transporters, BORs and NIPs (nodulin26-like intrinsic proteins). Both are plasma membrane localized, but have distinct transport properties and patterns of cell type-specific accumulation
