L-Carnosine

Lus piav qhia luv luv:

L-carnosine yog ib qho me me molecule dipeptide tsim los ntawm ob amino acids β-alanine thiab L-histidine. Nws yog dav pom nyob rau hauv cov leeg pob txha, lub plawv, lub hlwb thiab lwm cov hlab ntsha hauv lub cev. Ib tug natural antioxidant. Muaj peev xwm antioxidant thiab tiv thaiv glycosylation; tiv thaiv tsis-enzymatic glycosylation thiab protein coupling induced los ntawm acetoldehyde.

Khoom cim npe

L-Carnosine yog dipeptide uas muaj beta-alanine thiab histidine. Nws muaj nyob rau hauv cov leeg nqaij thiab lwm yam ntaub so ntswg. Nws muaj cov cuab yeej oxidant muaj zog vim nws tuaj yeem khawb ob hom reactive oxygen (ROS) thiab hom reactive nitrogen (RNS).Carnosine ua raws li cytosolic buffering tus neeg sawv cev thiab ua tus tswj hwm ntawm macrophage muaj nuj nqi. Ua tsaug rau nws lub peev xwm los tsim cov complexes nrog kev hloov pauv hlau, nws yog siv los tswj cov ntsiab lus ntawm kev hloov hlau ions hauv cov kua roj ntsha thiab cov ntaub so ntswg. Carnosine tuaj yeem tiv thaiv kev laus thiab tuaj yeem siv los tiv thaiv lossis kho cov teeb meem ntawm ntshav qab zib xws li paj hlwb puas, qhov muag tsis pom kev (cataracts), thiab teeb meem raum.

Muaj nuj nqi:

L-Carnosine tuaj yeem nce qhov txwv Hayflick hauv tib neeg fibroblasts, nrog rau qhov tshwm sim los txo qhov telomere luv luv. Carnosine kuj tseem suav tias yog geroprotector.
L-Carnosine yog cov tshuaj tiv thaiv zoo tshaj plaws uas tsis tau pom dua. (Carbonylation yog ib kauj ruam pathological nyob rau hauv lub hnub nyoog - ntsig txog degradation ntawm lub cev proteins.) Carnosine pab tiv thaiv daim tawv nqaij collagen cross-linking uas ua rau poob ntawm elasticity thiab wrinkles.
L-Carnosinehmoov kuj ua raws li kev tswj hwm ntawm zinc thiab tooj liab concentrations hauv paj hlwb, pab tiv thaiv overstimulation los ntawm cov neuroactive hauv lub cev substantiates.
L-Carnosine yog ib qho Super Anti-Oxidant uas quenches txawm tias feem ntau puas tsuaj dawb radicals: Hydroxyl thiab peroxyl radicals, superoxide, thiab singlet oxygen. Carnosine pab chelate ionic hlau (tshuaj co toxins los ntawm lub cev).

Daim ntawv thov:

1. Cov khoom noj tshiab tshiab. Hauv kev ua cov nqaij, carnosine tuaj yeem tiv thaiv cov roj oxidation thiab tiv thaiv cov xim nqaij. Carnosine thiab phytic acid tiv thaiv nyuj oxidation.
2. Kev siv tshuaj pleev ib ce 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 yog nyob rau hauv lub cev. Lub atom nquag heev lossis pab pawg ntawm atoms tuaj yeem oxidize lwm yam khoom hauv tib neeg lub cev.
3. Cov tshuaj hauv qhov ncauj siv hauv tshuaj thiab kev kho mob phais.
