Tlhaloso ea Sehlahisoa:
Carnosine (L-Carnosine), lebitso la saense β-alanyl-L-histidine, ke dipeptide e entsoeng ka β-alanine le L-histidine, e tiileng ka kristale.Lithishu tsa mesifa le boko li na le likarolo tse ngata haholo tsa carnosine.Carnosine e ile ea fumanoa ke setsebi sa k'hemistri sa Russia Gurevich hammoho le carnitine.
Liphuputso tse entsoeng United Kingdom, Korea Boroa, Russia le linaheng tse ling li bontšitse hore carnosine e na le matla a matla a antioxidant 'me e molemo' meleng oa motho.
Carnosine e bontšitsoe ho scavenge reactive oxygen radicals (ROS) le α-β unsaturated aldehydes e entsoeng nakong ea khatello ea kelello ea oxidative ka overoxidizing mafura a acid ka liseleng tsa lisele.
Ho sebetsa ha L-Carnosine:
Regulation of immune immune:
E na le phello ea ho laola ho itšireletsa mafung, 'me e ka laola mafu a bakuli ba nang le hyperimmunity kapa hypoimmunity.
Carnosine e ka bapala karolo e ntle haholo ho laola kaho ea thibelo ea 'mele ea motho ea ho itšireletsa mafung, ebang ke tšireletso ea cellular kapa humoral immune immune.
Endocrine:
Carnosine e ka boela ea boloka tekano ea endocrine ea 'mele oa motho.Tabeng ea mafu a endocrine le metabolic, tlatsetso e nepahetseng ea carnosine e ka laola boemo ba endocrine 'meleng.
Fepa 'mele:
Carnosine e boetse e na le karolo e itseng ea ho fepa 'mele, e ka fepang lisele tsa boko ba motho, ea ntlafatsa kholo ea li-neurotransmitters tsa boko, le ho matlafatsa methapo ea kutlo, e ka matlafatsang methapo le ho matlafatsa methapo.
