General description
二醋精是一种挥发性的乙酰化甘油，可用作电子烟中的调味剂。 它也存在于花油分泌植物中，据报道它是集油蜜蜂定位这些植物的信号，因此在授粉中起关键作用。
Application
- Organ-specific volatiles from Sonoran desert Krameria flowers as potential signals for oil-collecting bees.：鉴定刺球果花释放的特定挥发性物质，包括二乙酸甘油酯。这些挥发性物质是花油采集蜂的信号，体现一种特别的生态相互作用(Balbuena et al., 2024, Phytochemistry)。
- Techno-Economic Assessment and Sensitivity Analysis of Glycerol Valorization to Biofuel Additives via Esterification.：研究通过甘油酯化生产生物燃料添加剂（包括二乙酸甘油酯）的经济可行性，提供一种高性价比生产生物燃料的途径(Pandit et al., 2023, Industrial & Engineering Chemistry Research)。

During the evolutionary history of flowering plants, transitions between pollinator groups (pollinator shifts) have been frequent,1 and contributed to the spectacular radiation of angiosperms.2 Although the evolution of floral traits during pollinator shifts has been studied in real time under

The interaction between floral oil secreting plants and oil-collecting bees is one of the most specialized of all pollination mutualisms. Yet, the specific stimuli used by the bees to locate their host flowers have remained elusive. This study identifies diacetin
