With extensive experience and state-of-the-art technologies, Creative Proteomics use highly sensitive LC-ESI/MS method for the rapid identification and quantification of ergosteryl esters in fungi, which can satisfy the needs of academic and industrial study.
Ergosterol ester (EE) is a sterol lipid. Their structure consists of ergosterol, in which an ester bond is formed between the hydroxyl group of the steroidal structure and the fatty acid. Fatty acids can be variable length, hydroxylated and contain double bonds.
The biological function of ergosterol esters mainly revolves around the storage of ergosterol in yeast. Under conditions of growth retardation and after the death of the fungus, ergosterol is esterified and stored in cellular lipid droplets. Once esterified, the fatty acids of ergosterol esters will not be removed even under starvation conditions. In addition, some ergosterol esters also show strong growth inhibitory activity against deteriorating bacteria in dairy products and cosmetics.
The combination of MS instrument and liquid chromatography (LC) can effectively separate target lipid molecules from complex samples. Currently, a reliable and reproducible method using highly sensitive LC-MS/MS platform for the identification and quantification of EE in fungi has been established by the scientists at Creative Proteomics, which can satisfy the needs of academic and industrial study in your lab.
