3-Hydroxy-isobutanoyl-CoA is an important intermediate in the catabolism of isoleucine, a branched-chain amino acid. It is formed during the first step of isoleucine degradation, where isoleucine is initially transaminated to form 2-keto-3-methylvaleric acid, which is then converted to 3-hydroxy-isobutanoyl-CoA by the enzyme 2-keto-3-methylvalerate dehydrogenase. 3-hydroxy-isobutanoyl-CoA plays a crucial role in the breakdown of isoleucine, as it is further metabolized through a series of reactions to produce acetyl-CoA, which can then enter the citric acid cycle for energy production. The conversion of 3-hydroxy-isobutanoyl-CoA to acetyl-CoA involves several enzymes, including 3-hydroxy-isobutyryl-CoA hydrolase and 3-methylcrotonyl-CoA carboxylase, which ultimately lead to the production of acetyl-CoA and the release of carbon dioxide.
The CAS Registry Mumber 6008-94-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,0,0 and 8 respectively; the second part has 2 digits, 9 and 4 respectively. Calculate Digit Verification of CAS Registry Number 6008-94: (6*6)+(5*0)+(4*0)+(3*8)+(2*9)+(1*4)=82 82 % 10 = 2 So 6008-94-2 is a valid CAS Registry Number.
