Cytochrome a is a crucial heme protein found in the inner mitochondrial membrane, playing a vital role in the electron transport chain. It is a component of cytochrome c oxidase, the last enzyme in the chain, responsible for transferring electrons to molecular oxygen, thus facilitating the production of water and the generation of ATP. Cytochrome a contains a heme group with an iron atom at its center, which can switch between the Fe(II) and Fe(III) oxidation states, allowing it to accept and donate electrons. This protein is essential for cellular respiration and energy production, as it helps maintain the proton gradient across the mitochondrial membrane, driving ATP synthesis.
The CAS Registry Mumber 9035-34-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 9,0,3 and 5 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 9035-34: (6*9)+(5*0)+(4*3)+(3*5)+(2*3)+(1*4)=91 91 % 10 = 1 So 9035-34-1 is a valid CAS Registry Number.
