Cytochrome a1 is a heme-containing protein that plays a crucial role in the electron transport chain within the mitochondria of eukaryotic cells. It is a component of Complex IV, also known as cytochrome c oxidase, which is responsible for the final step of cellular respiration, where electrons are transferred to molecular oxygen to form water. Cytochrome a1 is characterized by its unique heme a group, which is covalently attached to the protein and contains a copper ion. This heme group, along with other redox-active centers in the enzyme, facilitates the transfer of electrons from cytochrome c to molecular oxygen, coupling this process with the pumping of protons across the mitochondrial membrane to generate an electrochemical gradient. This gradient is then harnessed by ATP synthase to produce ATP, the primary energy currency of the cell. The function of cytochrome a1 is essential for cellular energy metabolism and maintaining cellular homeostasis.
The CAS Registry Mumber 9035-35-2 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 5 respectively. Calculate Digit Verification of CAS Registry Number 9035-35: (6*9)+(5*0)+(4*3)+(3*5)+(2*3)+(1*5)=92 92 % 10 = 2 So 9035-35-2 is a valid CAS Registry Number.
