Sodium alginate ibasa rekubvisa iodine uye mannitol kubva kubrown algae senge kelp kana gungwa. Morekuru wayo unoumbwa ne β - D-mannuronic acid (M) uye α - L-guluronic acid (G) yakabatana ne (1 → 4) zvisungo. Sodium alginate aqueous solution ine high viscosity uye yakashandiswa semukobvu, stabilizer, emulsifier, nezvimwewo muchikafu. Sodium alginate chikafu chisina chepfu chakabatanidzwa muUnited States Pharmacopeia kare muna 1938. Sodium alginate ine yakawanda ye - COO -, iyo inogona kuratidza maitiro e polyanionic mumushonga wemvura uye ine imwe dhigirii yekunamatira. Inogona kushandiswa semutakuri wezvinodhaka kurapa mucosal tishu. Pasi pemamiriro eacidic, - Kana COO - ichishandurwa kuita COOH, iyo ionization degree inoderera, iyo hydrophilicity yesodium alginate inoderera, iyo molecular chain inoderera, uye pH kukosha kunowedzera Iboka reCOOH rinoramba richiparadzana, richiwedzera hydrophilicity yesodium alginate uye kutambanudza ketani yemamorekuru. Naizvozvo, sodium alginate ine yakakosha pH senitivity. Sodium alginate inogona kukurumidza kuumba gel pasi pemamiriro akanyorova. Kana ma cations akadai seCa2 + uye Sr2 + aripo, iyo Na + paG unit ichachinjana nemadivalent cations, uye iyo G unit inosunga kuti iite muchinjiko-yakabatana network chimiro, nokudaro ichigadzira hydrogel. Mamiriro ezvinhu ayo sodium alginate inoumba gel yakapfava, iyo inogona kudzivirira kusashanda kwemishonga inonzwisisika, mapuroteni, masero, enzymes uye zvimwe zvinoshanda zvinhu. Nekuda kweaya akanakisa zvivakwa, sodium alginate yakashandiswa zvakanyanya muindasitiri yechikafu neminda yemishonga.
