Description
L-ASPARAGINE-15N2 is a stable isotope of the amino acid asparagine, which is a key component in the synthesis of proteins. The isotopic label 15N2 indicates that the nitrogen atoms in the molecule are the heavier isotopes of nitrogen, allowing for the tracking and study of metabolic processes involving asparagine in biological systems.
Used in Biological and Biochemical Research:
L-ASPARAGINE-15N2 is used as a research tool for studying protein metabolism, biosynthesis, and nutrient uptake in organisms. Its stable isotopic label makes it a valuable tool for tracing the fate of asparagine in biological processes.
Used in Stable Isotope Labeling Studies:
L-ASPARAGINE-15N2 is used as a tracer in stable isotope labeling studies to investigate metabolic pathways and protein dynamics.
Check Digit Verification of cas no
The CAS Registry Mumber 748757-99-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 7,4,8,7,5 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 748757-99:
(8*7)+(7*4)+(6*8)+(5*7)+(4*5)+(3*7)+(2*9)+(1*9)=235
235 % 10 = 5
So 748757-99-5 is a valid CAS Registry Number.

The present invention provides a stable isotope-labeled amino acid which is at least one of amino acids constituting a protein and which has at least one of the following labeling patterns:(a) hydrogen atoms except at least one hydrogen atom in one or more methylene groups are deuterated,(b) hydrogen atoms in one of prochiral gem-methyl groups are completely deuterated,(c) hydrogen atoms in prochiral methyl groups are partially deuterated, and(d) all hydrogen atoms except one of them in methyl group are deuterated and hydrogen atoms in the aromatic ring are partially deuterated. With the stable isotope-labeled amino acid, the deuteration of protein can be attained without damaging the NMR sensitivity of remaining hydrogen nucleus and, in addition, the rapid, accurate analysis of NMR spectrum of a high-molecular protein which is beyond the limitation in the prior art and the determination of the stereo-structure can be performed at the same time.
