Uses
N2-Cbz-D-glutamine is an N-Cbz-protected form of D-Glutamine (G597295). D-Glutamine is an unnatural isomer of L-Glutamine (G597000) that is present in human plasma an is a source of liberated ammonia. D-Glutamine can be synthesized by enzymatic means or can be found in cheeses, wine and vinegars as well. It is often used to determine the activity of Glutamine synthetase, an enzyme that is commonly found in the mammalian liver and brain that controls the use of nitrogen in cells.
Check Digit Verification of cas no
The CAS Registry Mumber 13139-52-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,1,3 and 9 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 13139-52:
(7*1)+(6*3)+(5*1)+(4*3)+(3*9)+(2*5)+(1*2)=81
81 % 10 = 1
So 13139-52-1 is a valid CAS Registry Number.

PAPAIN-ASSISTED RESOLUTION OF NATURAL AND XENOBIOTIC α-AMINO ACIDS
Moriniere, J. L.,Danree, B.,Lemoine, J.,Guy, A.
, p. 441 - 444 (2007/10/02)
A new and convenient method for the preparation of pure enantiomers of α-amino acids is described.Industrial papain, catalyzes the synthesis of L-Z-amino acid ethyl esters in ethanolic medium, with good yields.These esters are obtained from DL-Z-amino acids with 100percent optical purity.Unreactive D-Z-amino acids are readily isolated from reaction medium.Physical constants of natural and xenobiotic L-Z-amino acid esters and D-Z-amino acids are described.
