一般描述
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。
应用
- Engineering Escherichia coli for high-yielding 2,5-Dimethylpyrazine synthesis from L-Threonine by reconstructing metabolic pathways and enhancing cofactors regeneration.: This study details the genetic engineering of *E. coli* to enhance the production of 2,5-Dimethylpyrazine from L-Threonine. By reconstructing metabolic pathways and improving cofactor regeneration, the researchers achieved higher yields, presenting a significant advancement for industrial bioproduction of this compound (Liu et al., 2024).
- Pyrazines Biosynthesis by Bacillus Strains Isolated from Natto Fermented Soybean.: This research explores the natural biosynthesis of pyrazines, including 2,5-Dimethylpyrazine, by *Bacillus* strains isolated from natto. The findings contribute to understanding the microbial production of flavor compounds and their potential applications in food biotechnology (Klosowski et al., 2021).

Mature female mice, grouped in the absence of a male stimulus, exhibit a suppressed estrous cycle (the so-called Lee-Boot effect). We have designed a series of experiments to elucidate the involvement of the adrenal gland in this phenomenon. Our initial

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 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))
