562-43-6 Usage
General Description
Valeric acid, 2,3-dihydroxy-3-methyl- is a specific form of valeric acid, a natural fatty acid. This particular chemical compound is characterized by the presence of two hydroxyl groups (2,3-dihydroxy) and a methyl group (3-methyl) on the valeric acid molecule. It is commonly found in some natural sources, such as certain plants and microorganisms. Valeric acid, 2,3-dihydroxy-3-methyl- has several potential industrial and pharmaceutical applications, including its use as a precursor in the synthesis of various organic compounds and as a potential therapeutic agent. Research is ongoing to further explore and develop the potential uses and benefits of this chemical compound.
Check Digit Verification of cas no
The CAS Registry Mumber 562-43-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,6 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 562-43:
(5*5)+(4*6)+(3*2)+(2*4)+(1*3)=66
66 % 10 = 6
So 562-43-6 is a valid CAS Registry Number.

Construction of an L-isoleucine overproducing strain of Escherichia coli K-12
Hashiguchi, Ken-Ichi,Takesada, Hiroko,Suzuki, Eiichiro,Matsui, Hiroshi
, p. 672 - 679 (2007/10/03)
The genes for a threonine deaminase that is resistant to feedback inhibition by L-isoleucine and for an active acetohydroxyacid synthase II were introduced by a plasmid into a L-threonine-producing recombinant strain of Escherichia coli K-12. Analysis of culture broth of the strain using 13C nuclear magnetic resonance suggested that α, β-dihydroxy-β-methylvalerate (DHMV) and α-keto-βmethylvalerate (KMV), the third and the fourth intermediates in the L-isoleucine biosynthetic pathway from L-threonine, respectively, accumulated in the medium in amounts comparable to that of L-isoleucine. The ratio of accumulated L-isoleucine:DHMV:KMV were approximately 2:1:1. The concentration of accumulated L-isoleucine increased by twofold after the additional introduction of the genes for dihyroxyacid dehydratase (DH) and transaminase-B (TA-B), and the intermediates no longer accumulated. The resultant strain TVD5 accumulated 10 g/1 of L-isoleucine from 40 g/1 of glucose.
