AI Article Synopsis
- Zooglan, an exopolysaccharide from Zoogloea ramigera 115, significantly speeds up the methanolysis of phosphatidylcholine, especially dipalmitoylphosphatidylcholine (DPPC), when reacted in pure methanol at 30°C.
- * The reaction's progress was monitored using techniques like thin-layer chromatography (TLC) and nuclear magnetic resonance (NMR) spectroscopy.
- * Zooglan increased the methanolysis rate of DPPC by about 170 times compared to control substances, showcasing its potential as an eco-friendly catalyst for such reactions.
Article Abstract
Zooglan, a weakly acidic exopolysaccharide produced by Zoogloea ramigera 115, catalyzed the preferential methanolysis of phospatidylcholine compared to other phospholipids when the reaction was carried out in pure methanol at 30 degrees C. The reaction was monitored by thin-layer chromatography (TLC) as well as (1)H and (31)P nuclear magnetic resonance (NMR) spectrometry. Zooglan enhanced the rate of methanolysis of dipalmitoylphosphatidylcholine (DPPC) up to about 170-fold compared to controls such as DPPC alone, pyruvic acid, succinic acid and acetic acid. Furthermore, the methanolysis was different depending on the head groups of the phospholipids. Through this study, we have shown that zooglan can act as an environmentally benign catalytic polysaccharide for methanolysis in pure methanol solution.
