For newborns and growing babies, human milk oligosaccharides (HMOs) are regarded as the ideal nutrition source. A better design of new therapeutic agents with anti-infective qualities and better artificial nutrition products will depend on a better knowledge of the features of HMOs, the connection between their structure and function, and the role of HMOs in infant growth and development.

As a form of mixed oligosaccharide, HMOs present a challenging separation and quantitative detection task due to the intricacy of their native structure and distinctive chemical characteristics. The sensitivity, repeatability, high output, and speed of the technology and tools are also important factors in the profiling of HMOs. HMOs have been characterized and quantified using a range of chemical methods over the years, including MS, NMR, HPLC, CE, etc.

There are various techniques for analyzing HMOs. One of the first discovery techniques for oligosaccharide measurement is direct HPLC-UV. Underivatized oligosaccharides and the relative isolation of various isomers can be examined using high-performance anion exchange chromatography (HPAEC) with pulsed amperometric detection (PAD). HMOs can be analyzed using hydrophilic interaction chromatography (HILIC) after being labeled with fluorescence molecules. It is frequently used in conjunction with chromatography because electrospray ionization mass spectrometry (ESI-MS) has a broad measurement range and can provide information about the linking sequence and linkage structure of oligosaccharides. The structure of the glycosidic bonds, the number of residues, the connection, and the linkage pattern between the saccharide units of sugar compounds can all be resolved using NMR.
HMO family has many members and they can be determined separately.
HMO are complex unconjugated glycans associated with positive infant health outcomes. HMO profiling is very meaningful, with the function of studying the potential applications of HMO.
Due to the multiple connection possibilities of the monosaccharides used as building blocks, HMOs exhibit very complex structural diversity. Modern analytical technologies are highly required to clarify their structure-function link.
