一般說明

2,5-二甲基吡嗪是一种吡嗪类化合物,主要在烹煮或烘烤过程中,由于糖类和蛋白质之间的美拉德反应,在熟米或烘烤花生等食品中形成。

應用


  • 通过重建代谢途径和增强辅因子再生,工程化大肠杆菌由L-苏氨酸高产合成2,5-二甲基吡嗪。:研究详细介绍了*大肠杆菌*的基因工程,可提高由L-苏氨酸生成2,5-二甲基吡嗪的效率。通过重建代谢途径和改善辅因子再生,研究人员实现了更高的产量,这是该化合物工业生物生产的重大进展(Liu et al., 2024)。

  • 从纳豆发酵大豆中分离的芽孢杆菌菌株生物合成吡嗪的研究。:研究探讨了从纳豆中分离的*芽孢杆菌*菌株对2,5-二甲基吡嗪等吡嗪类化合物的天然生物合成。这些发现有助于了解风味化合物的微生物生产及其在食品生物技术中的潜在应用(Klosowski et al., 2021)。

The social and reproductive behaviors of most mammals are modulated by pheromones, which are perceived by the vomeronasal organ (VNO). Vomeronasal transduction in vertebrates is activated through G-protein-coupled receptors, which in turn leads to the generation of inositol 1,4,5-trisphosphate (IP(3))

Based on a variety of recent findings, the Grueneberg ganglion (GG) in the vestibule of the nasal cavity is considered as an olfactory compartment. However, defined chemical substances that activate GG neurons have not been identified. In this study, the

The quantum yield for HCN formation via 248 nm photodissociation of 2,3-, 2,5-, and 2,6-dimethylpyrazine (DMP, C6N2H8) was measured using diode laser probing of the HCN photoproduct. The total quantum yield is phi = 0.039 +/- 0.07, 0.14 +/- 0.02

Social behaviors of most mammals are affected by chemical signals, pheromones, exchanged between conspecifics. Previous experiments have shown that behavioral responses to the same pheromone differ depending on the sex and endocrine status of the respondent. Although the exact mechanism
