Nkọwa ngwaahịa:
N-acetyl-D-glucosamine bụ ụdị ọgwụ ọhụrụ nke biochemical, nke bụ akụkụ nke polysaccharides dị iche iche na ahụ, ọkachasị ọdịnaya exoskeleton nke crustaceans bụ nke kachasị elu. Ọ bụ ọgwụ na-agwọ ọrịa maka ọgwụgwọ rheumatism na ọrịa ogbu na nkwonkwo.
Enwere ike iji ya dị ka antioxidants nri na ihe mgbakwunye nri maka ụmụ ọhụrụ na ụmụaka, ihe ụtọ maka ndị ọrịa mamịrị.
Mmetụta nke N-acetyl glucosamine:
A na-ejikarị ya maka ịkwalite ọrụ nke sistemu ahụ ji alụso ọrịa ọgụ nke mmadụ, na-egbochi oke uto nke mkpụrụ ndụ kansa ma ọ bụ fibroblasts, yana igbochi na ịgwọ ọrịa kansa na etuto ọjọọ. A pụkwara ịgwọta mgbu nkwonkwo mgbu.
Immunomodulation
Glucosamine na-ekere òkè na metabolism shuga n'ime ahụ, dị ebe niile n'ime ahụ, yana mmadụ na anụmanụ nwere mmekọrịta chiri anya.
Glucosamine na-ekere òkè na nchebe nke ahụ site na ijikọta ya na ihe ndị ọzọ dị ka galactose, glucuronic acid na ihe ndị ọzọ na-emepụta ngwaahịa dị mkpa na ihe omume ndụ dị ka hyaluronic acid na keratin sulfate.
Na-agwọ ọrịa ogbu na nkwonkwo
Glucosamine bụ ihe dị mkpa na-edozi ahụ maka ịmepụta mkpụrụ ndụ cartilage mmadụ, ihe bụ isi maka njikọ aminoglycans, na anụ ahụ anụ ahụ nke cartilage articular dị mma.
N'ime afọ, enweghị glucosamine na ahụ mmadụ na-adịwanye njọ, na cartilage articular na-aga n'ihu na-emebi ma na-agwụ ike. Ọtụtụ nchọpụta ahụike na United States, Europe na Japan egosila na glucosamine nwere ike inye aka rụkwaa na ịnọgide na-enwe cartilage ma kpalie uto nke mkpụrụ ndụ cartilage.
Antioxidant, mgbochi ịka nká
Glucosamine nwere ike chelate Fe2+ nke ọma, ma n'otu oge ahụ nwere ike ichebe macromolecules lipid site na mmebi nke hydroxyl radical oxidation, ma nwee ikike antioxidant.
Antiseptik na antibacterial
Glucosamine nwere mmetụta antibacterial doro anya na ụdị nje 21 a na-ahụkarị na nri, na glucosamine hydrochloride nwere mmetụta nje bacteria pụtara ìhè.
Site na mmụba nke mkpokọta glucosamine hydrochloride, mmetụta antibacterial ji nwayọọ nwayọọ na-esiwanye ike.
