Abstract:
The purpose of this study was to investigate the degradation mechanism of Bifidobacterium on breast milk oligosaccharides (HMOs) and its application in infant nutrition. The composition and characteristics of HMOs were introduced, and the degradation mechanism of HMOs by Bifidobacterium was described, including intracellular and extracellular digestion and species-specific differences. The interaction between Bifidobacterium and Bacteroides in the process of degrading HMOs and its effect on intestinal microecology were analyzed. The effects of HMO formula milk powder on the intestinal microbiota of infants were discussed, including simulating breast milk composition, regulating intestinal flora and immune function, infection prevention, and brain development. Finally, the research results are summarized, and future research directions are proposed to provide directions for research in the field of infant nutrition.

01:15Hydrolysis
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
