The abundances of each HMO are presented as a relative amount of the total measured area under the curve as determined by High Performance Anion Exchange Chromatography with Pulsed Amperometric Detection (HPAEC-PAD) for each HMO.

^aCompounds 1–13 (90% of all oligosaccharides in the 25-HMO blend).

^bCompounds 14–32 (not quantified).
