  • 三(羟甲基)甲基甘氨酸

    N-tris(hydroxymethyl)methylglycine

化合物简介

Tricine is an organic compound that is used in buffer solutions. The name tricine comes from tris and glycine, from which it was derived. It is a white crystalline powder that is moderately soluble in water. It is a zwitterionic amino acid that has apKa1 value of 2.3at 25 °C, while itspKa2at 20 °C is 8.15. Its useful buffering range of pH is 7.4-8.8. Along with bicine, it is one of Good's buffering agents. Good first prepared tricine to buffer chloroplast reactions.
