L-Carnosine | 305-84-0
Ingcaciso yeMveliso:
I-Carnosine (L-Carnosine), igama lenzululwazi β-alanyl-L-histidine, yidipeptide eyenziwe nge-β-alanine kunye ne-L-histidine, i-crystalline solid. Izihlunu kunye nezicubu zengqondo ziqulethe i-carnosine ephezulu kakhulu. I-Carnosine yafunyanwa ngusokhemisti waseRashiya uGurevich kunye ne-carnitine.
Izifundo e-United Kingdom, eMzantsi Korea, eRashiya nakwamanye amazwe abonise ukuba i-carnosine inamandla okulwa ne-antioxidant kwaye iluncedo kumzimba womntu.
I-Carnosine ibonakaliswe ukukhupha i-oxygen radicals (ROS) kunye ne-α-β unsaturated aldehydes eyenziwe ngexesha loxinzelelo lwe-oxidative ngokugqithiswa kwe-fatty acids kwi-membrane zeseli.
Ummiselo wokugonyeka:
Inempembelelo yokulawula ukhuseleko, kwaye inokulawula izifo zezigulane ezine-hyperimmunity okanye i-hypoimmunity.
I-Carnosine inokudlala indima entle kakhulu ekulawuleni ukwakhiwa komqobo wokugonyeka komntu, nokuba kukungakhuseleki kwamaselula okanye ukugonywa kwe-humoral.
I-Endocrine:
I-Carnosine inokugcina ibhalansi ye-endocrine yomzimba womntu. Kwimeko ye-endocrine kunye nezifo ze-metabolic, ukuxhaswa ngokufanelekileyo kwe-carnosine kunokulawula inqanaba le-endocrine emzimbeni.
Yondla umzimba:
I-Carnosine nayo inendima ethile ekondleni umzimba, onokondla izicubu zobuchopho bomntu, ukuphucula ukukhula kwee-neurotransmitters zobuchopho, kwaye zondle iziphelo zemithambo-luvo, ezinokondla ii-neurons kwaye zondle imithambo-luvo.
