Hydrophilic interaction chromatography (or hydrophilic interaction liquid chromatography, HILIC) is a variant of normal phase liquid chromatography that partly overlaps with other chromatographic applications such as ion chromatography and reversed phase liquid chromatography. HILIC uses hydrophilic stationary phases with reversed-phase type eluents. The name was … WebGlycation is an important post-translational modification that is linked to diabetes, cataract, Alzheimer’s, Rheumatoid arthritis and Parkinson’s disease. 1 This reaction occurs between a reducing sugar and a primary amine at the N-terminus of protein or the sidechain of Lysine residues. Ultimately this interaction leads to advanced glycation end products (AGEs) that …
