L-Carnosine | 305-84-0 : kuv
Product Description:
Carnosine (L-Carnosine), lub npe scientific β-alanyl-L-histidine, yog dipeptide muaj li ntawm β-alanine thiab L-histidine, crystalline khoom. Cov leeg nqaij thiab lub hlwb muaj cov carnosine ntau heev. Carnosine tau tshawb pom los ntawm Lavxias chemist Gurevich nrog rau carnitine.
Kev tshawb fawb hauv tebchaws United Kingdom, Kaus Lim Qab Teb, Russia thiab lwm lub tebchaws tau pom tias carnosine muaj zog antioxidant muaj peev xwm thiab muaj txiaj ntsig zoo rau tib neeg lub cev.
Carnosine tau pom tias tshem tawm cov pa oxygen radicals (ROS) thiab α-β unsaturated aldehydes tsim thaum lub sij hawm oxidative kev nyuaj siab los ntawm overoxidizing fatty acids nyob rau hauv cell membranes.
Kev cai ntawm kev tiv thaiv kab mob:
Nws muaj cov nyhuv tswj kev tiv thaiv kab mob, thiab tuaj yeem tswj cov kab mob ntawm cov neeg mob hyperimmunity lossis hypoimmunity.
Carnosine tuaj yeem ua lub luag haujlwm zoo hauv kev tswj hwm kev tsim kho ntawm tib neeg lub cev tiv thaiv kab mob, txawm hais tias nws yog cellular tiv thaiv kab mob los yog kev tiv thaiv humoral.
Endocrine:
Carnosine tseem tuaj yeem tswj hwm qhov sib npaug ntawm endocrine ntawm tib neeg lub cev. Nyob rau hauv cov ntaub ntawv ntawm endocrine thiab cov kab mob metabolic, kev kho kom zoo ntawm carnosine tuaj yeem tswj cov qib endocrine hauv lub cev.
Nourish lub cev:
Carnosine kuj tseem muaj lub luag haujlwm tseem ceeb hauv kev txhawb nqa lub cev, uas tuaj yeem txhawb nqa tib neeg lub hlwb cov ntaub so ntswg, txhim kho kev loj hlob ntawm lub hlwb neurotransmitters, thiab txhawb cov paj hlwb, uas tuaj yeem txhawb cov neurons thiab txhawb cov hlab ntsha.
