Mannanoligosaccharides obtained from the cell walls of the yeast Saccharomyces cerevisiae act as a valuable support for the natural defense mechanisms found in the digestive system. These compounds effectively support the balance of intestinal microbiota, helping to maintain proper intestinal function and stimulating the immune system to better respond to external factors.
Learn the differences between prebiotics and probiotics.
Probiotic
Probiotics are living microbial cells (primarily lactic acid bacteria of the genera Lactobacillus and Bifidobacterium ) that exhibit specific biochemical characteristics that enable them to survive the harsh conditions of the gastrointestinal tract. A key element of their metabolism is the homo- or heterofermentative fermentation of carbohydrates , which converts glucose into lactic acid and short-chain fatty acids (SCFAs).
This process drastically lowers the pH in the intestinal lumen, creating an unfavorable, acidic environment that inhibits the proliferation of pathogenic putrefactive bacteria. Furthermore, the biochemical activity of probiotics includes the production of specific enzymes (such as beta-galactosidase) and the synthesis of antibacterial substances, such as bacteriocins and hydrogen peroxide , which selectively destroy the cell membranes of pathogenic microorganisms.
Prebiotic
Prebiotics are organic compounds of oligosaccharide and polysaccharide nature (such as PHGG fiber, MOS mannanoligosaccharides, or arabinogalactan) that are not digested by human endogenous enzymes (e.g., salivary amylase or small intestinal brush border enzymes). Due to their specific glycosidic bonds (often beta-type), the human digestive system lacks the enzymes capable of hydrolyzing them, allowing these molecules to reach the large intestine intact.
In the large intestine, prebiotics undergo bacterial anaerobic (anaerobic) fermentation by endogenous microflora. This pathway leads to the breakdown of complex sugar chains into simpler monomers and the subsequent synthesis of short-chain fatty acids (SCFAs), primarily acetic acid, propionic acid, and butyric acid. Butyric acid, in particular, plays a key biochemical role, serving as the primary energy source (nutrient substrate) for colonocytes (intestinal epithelial cells), stimulating their proliferation, sealing the intestinal barrier, and modulating the local immune response.
Mannanoligosaccharides (MOS) are specific polysaccharides that compose the outer cell wall of yeast and act as advanced modulators of the intestinal environment. From a biochemical perspective, their key role is to competitively bind pathogens . Many pathogenic bacteria (possessing lectins, or adhesion proteins, on their surface) strive to anchor themselves to the intestinal epithelium, which is the first step towards infection and disruption of the microbiome.
The structure of MOS mimics intestinal epithelial receptors, allowing harmful microorganisms to readily “stick” to MOS molecules rather than to the intestinal walls. The resulting complex is then safely eliminated from the body along with fecal masses through peristalsis. This mechanism not only protects the intestinal barrier from colonization by pathogens but also relieves the local immune system (GALT – gut-associated lymphoid tissue) and stimulates the growth of beneficial saprophytic bacteria, which gain space to dominate the intestinal ecosystem.
