According to LIPID MAPS classification, sterol lipids are further divided into sterols, steroids, bile acids and derivatives.
Sterols exist in the cell membranes of plants, animals, and microorganisms, and are called phytosterols, zoosterols, and mycosterols, respectively. Cholesterol (CHO) is the main sterol in vertebrates. Ergosterol (ERG) plays a key role in fungi. Plants usually have more complex sterol components.
Steroids function as important components of cell membranes and many of them are signaling molecules. All steroids are manufactured in cells from the sterols lanosterol (animals and fungi) or cycloartenol (plants). Lanosterol and cycloartenol are derived from the cyclization of the triterpene squalene.
With an integrated set of separation, characterization, identification and quantification systems featured with excellent robustness & reproducibility, high and ultra-sensitivity, Creative Proteomics provides reliable, rapid and cost-effective sterol lipids analysis services.
We are equipped with TSQ™ 9000 Triple Quadrupole GC-MS/MS System and Q Exactive Orbitrap LC-MS/MS System for targeted lipidomics service to ensure detection sensitivity and data accuracy.
