Ceramide has a strong ability to associate with water molecules. It maintains skin moisture by forming a network structure in the stratum corneum. In addition, it also plays an important role in maintaining the integrity of cell membranes, cell stress response, inflammatory signal transduction and cell apoptosis. Creative Proteomics uses liquid chromatography mass spectrometry (LC-MS) method to identify the samples, which can effectively and accurately detect the changes in the content of ceramide. https://lipidomics.creativ...
