Determination of true molar masses of collagen peptides

contributed by PSS | 02/03/2021

Collagen peptides are relatively small proteins with typical molar masses of less than 10.000 g/mol. They exhibit a molar mass distribution, MMD, which influences their properties.

A monograph by GME describes a procedure how to determine true MMDs for collagen peptides using standard Liquid Chromatography, LC, equipment (1). The LC setup comprises an isocratic pump, an injection system, GPC/SEC columns and an UV/VIS detector.
