Hang on to those branches! Amylopectin, the major polysaccharide of starch, is a predominantly α(1,4)‐linked glucan whose properties are defined by its size and the number, distribution, and length of its α(1,6)‐linked branches. The amphiphilic probe HPTS‐C 16 H 33 binds to terminal helical branches longer than 12 glucose units (green), which allows for a detailed quantitative characterization of polysaccharide branching by 1 H NMR spectroscopy.
