An Enterprise Edition of SimLipid® is now available. If you are working with a private custom database or with proprietary data, the enterprise edition is the secure tool you are looking for to resolve novel lipids. You can add to or delete lipid structures from the database or create your own sub-database for narrowing down the search, right from the convenience of your workstation. Structural information for multiple lipids can be stored in a single file and added to the database, saving time.
When you buy the Enterprise Edition, you get:
The main biological functions of lipids include energy storage, acting as structural components of cell membranes, and participating as important signaling molecules.
Comparative studies of complex lipid mixtures found in cells and tissues could potentially reveal lipid biomarkers. The presence of lipids in membranes is reflective of the physiological state of an organism at a given time. Targeted and non-targeted approaches based on chromatography and mass spectrometry are employed for such studies. Both the approaches involve identification and measurement of lipids in the samples.
The challenges with mass spectrometry based lipidomics are the chemical complexity and large range of concentration of thousands of lipid species that are present in biological samples. Moreover, identification of lipids requires sophisticated software since automated interpretation of lipid MS/MS spectra is more challenging as compared to other biopolymers such as DNA, carbohydrates or peptides since lipids show much less standardized fragment mass spectra. Each lipid class has its own fragmentation patterns as well as ionization efficiency.
