Galactokinase is an enzyme that plays a crucial role in the metabolism of galactose, a sugar found in milk and dairy products. It catalyzes the first step in the Leloir pathway, which is responsible for converting galactose into glucose-1-phosphate, a compound that can be further metabolized for energy production. The enzyme transfers a phosphate group from ATP to galactose, forming galactose-1-phosphate. This reaction is essential for the proper utilization of galactose in the body, and deficiencies in galactokinase can lead to a rare genetic disorder called galactosemia, which can cause severe health issues if not managed properly.
The CAS Registry Mumber 9030-53-9 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 0 respectively; the second part has 2 digits, 5 and 3 respectively. Calculate Digit Verification of CAS Registry Number 9030-53: (6*9)+(5*0)+(4*3)+(3*0)+(2*5)+(1*3)=79 79 % 10 = 9 So 9030-53-9 is a valid CAS Registry Number.
