Mechanism ntawm kev ua
Normal Coupling:
- Sab hauv mitochondrial membrane muaj ob lub hauv paus tseem ceeb: cov khoom siv hluav taws xob thauj khoom (uas ua kom muaj cov proton gradient) thiab ATP synthase (uas siv cov gradient los ua ke ATP).
- Ob lub tshuab no ua ke ua ke los ntawm proton gradient: protons tawm los ntawm cov saw hlau thauj hluav taws xob yuav tsum ntws rov qab los ntawm ATP synthase los tsav ATP synthesis.
- Qhov kev sib txuas no ua kom muaj kev sib tw ntawm cov roj combustion thiab kev tsim hluav taws xob.
Lub luag haujlwm ntawm Uncoupling Agents:
- Uncoupling cov neeg ua haujlwm ntxig rau hauv mitochondrial membrane, muab txoj hauv kev rau protons kom hla ATP synthase.
- Kev cuam tshuam ntawm kev sib txuas: Cov saw hlau thauj hluav taws xob txuas ntxiv ua haujlwm, tab sis cov protons uas tsim tawm tsis tas siv rau ATP ntau lawm.
- Vim li cas: Roj combustion accelerates, tab sis ATP ntau lawm txo es tsis txhob nce.
BAM15 yog cov molecule zoo li no -nwsreversibly khi rau thiab thauj protons, tsim ib tug bypass nyob rau hauv lub puab mitochondrial membrane, yog li rhuav lub qub coupling ntawm lub electron thauj saw thiab ATP synthesis.

BAM15 peptide Powder yog ib qho kev xaiv ntau ntawm cov neeg nqa khoom proton uncoupling tus neeg sawv cev. Nws nce proton permeability los ntawm kev nkag mus rau hauv lub mitochondrial membrane, muab txoj hauv kev rau cov protons kom bypass ATP synthase, yog li ua rau txo qis hauv daim nyias nyias, lub zog ua pa nce ntxiv, thiab txo qis hauv ATP synthesis efficiency. Piv rau FCCP thiab DNP, nws cov txiaj ntsig tseem ceeb nyob hauv kev ua haujlwm tsuas yog nyob rau sab hauv mitochondrial membrane ntau dua li cov plasma membrane, yog li txo qis - lub hom phiaj toxicity thiab muab lub qhov rais dav dav.
