Microbiote
PolysaccharidesLes polysaccharides (parfois appelés glycanes, polyosides, polyholosides ou glucides complexes) sont des polymères constitués de plusieurs oses liés entre eux par des liaisons osidiques.
Les polyosides les plus répandus du règne végétal sont la cellulose et l’amidon, tous deux polymères du glucose.
De nombreux exopolysaccharides (métabolites excrétés par des microbes, champignons, vers (mucus) du ver de terre) jouent un rôle majeur - à échelle moléculaire - dans la formation, qualité et conservation des sols, de l'humus, des agrégats formant les sols et de divers composés "argile-exopolysaccharide" et composites "organo-minéraux"(ex : xanthane, dextrane, le rhamsane, succinoglycanes...).
De nombreux polyosides sont utilisés comme des additifs alimentaires sous forme de fibre (inuline) ou de gomme naturelle.
Ce sont des polymères formés d'un certain nombre d'oses (ou monosaccharides) ayant pour formule générale : -[Cx(H2O)y)]n- (où y est généralement x - 1). On distingue deux catégories de polysaccharides : Les homopolysaccharides (ou homoglycanes) constitués du même monosaccharide : fructanes, glucanes, galactanes, mannanes ; les hétéropolysaccharides (ou hétéroglycanes) formés de différents monosaccharides : hémicelluloses.
Les constituants participant à la construction des polysaccharides peuvent être très divers : hexoses, pentoses, anhydrohexoses, éthers d'oses et esters sulfuriques.
Selon l'architecture de leur chaîne, les polysaccharides peuvent être : linéaires : cellulose ; ramifiés : gomme arabique, amylopectine, dextrane, hémicellulose et mixtes : amidon.

| Résumé : |
The skin is colonized by billions of bacteria that participate in the regulation of immunity and barrier functions, preserving the microbiota homeostasis are essential to maintain a healthy skin and mucosa.
The vaginal microbiota is composed of 90% lactic acid bacteria (lactobacilli) that colonize the vagina at puberty. This microbiota is critical to maintaining vaginal health. About 250 bacterial species have been identified in the human vagina. In healthy women of reproductive age, the vaginal microbiota is generally dominated by the genus Lactobacillus, with a prevalence of L. crispatus (59%), L. gasseri (16%), L. iners (22%), and L jensenii (3%) species. However, in most cases, only one species of lactobacilli is present.
These lactobacilli have very specific functions. They stimulate the local immune system and form biofilms that create real protective shields. They transform glycogen secreted by the genital mucosa cells into lactic acid, thus creating an acidic environnent necessary to maintain the vaginal pH between 3.5 and 4.5.
The vaginal pH reflects the vaginal microbiota's health: a pH higher than 4.5 indicates an imbalance in the vaginal flora, also called dysbiosis. Dysbiosis can be accompanied by symptoms such as unusual discharge, itching or vulvar pain and can sometimes lead to infection (mycosis, vaginosis etc.). During menopause, the pH is naturally 4.5.
Each woman hosts several types of lactobacilli which will evolve during her cycle and her life according to hormonal variations, her environment, her intimate hygiene, her sexual life, etc.
During menopause, there is a progressive decrease in estrogens, and therefore also in lactobacilli of the vaginal mucosa. It is estimated that between 55% to 70% of menopausal women suffer from vaginal dryness.
Furthermore, more than 30% of postmenopausal women and 16% of women in general, are suffering from dyspareunia (pain during sexual intercourse), an unrecognized and often hidden problem mostly due to a microbiota imbalance. Women speak more and more about their intimacy and want to limit their discomfort but very few products meet consumers' specific needs. |
