L-carnosine (β-alanyl-L-histidine) yog dipeptide ntawm cov amino acids β-alanine thiab histidine. Nws yog heev concentrated nyob rau hauv cov leeg nqaij thiab lub paj hlwb. Carnosine muaj ntau yam muaj txiaj ntsig zoo antioxidant, uas tuaj yeem tshem tawm cov pa oxygen reactive thiab α-β unsaturated aldehydes tsim los ntawm fatty acid peroxidation ntawm cell membranes thaum oxidative kev nyuaj siab. Carnosine kuj yog zwitterion, ib qho nruab nrab molecule nrog qhov zoo thiab qhov tsis zoo.
L-carnosine yog dipeptide uas muaj zog antioxidant thiab tiv thaiv glycation; blocks non-enzymatic glycosylation thiab protein ntau sib txuas induced los ntawm reactive aldehydes.

Daim ntawv thov zaub mov
L-carnosine tsis tsuas yog tuaj yeem cuam tshuam cov roj oxidation, tab sis kuj muaj kev nyab xeeb thiab kev noj qab haus huv. Yog li, L-carnosine yog cov khoom noj zoo tshaj plaws antioxidant nrog rau daim ntawv thov nqi.
Kev siv tshuaj pleev ib ce
Siv rau hauv tshuaj pleev ib ce, nws tuaj yeem tiv thaiv kev laus ntawm daim tawv nqaij thiab tawv nqaij dawb. Carnosine tuaj yeem tiv thaiv cov dawb radicals tsim los ntawm kev haus luam yeeb, thiab cov dawb radical no tuaj yeem ua rau daim tawv nqaij puas ntau dua li hnub ci. Dawb radicals muaj zog heev nyob rau hauv tib neeg lub cev. Cov atom lossis pawg ntawm atoms tuaj yeem oxidize lwm yam khoom hauv tib neeg lub cev.
Kev siv tshuaj kho mob
1. Ntxiv nrog rau inhibiting cov txheej txheem peroxidation ntawm cov cell membrane, carnosine tuaj yeem cuam tshuam cov tshuaj peroxidation hauv cov cell, uas yog, carnosine tuaj yeem cuam tshuam txhua kauj ruam ntawm cov tshuaj tiv thaiv oxidation nyob rau hauv tag nrho peroxidation saw nyob rau hauv lub cev;
