71-00-1 Usage

General Description

Histidine is an essential amino acid that is crucial for the synthesis of proteins in the human body. It plays a key role in the growth and repair of tissues, as well as in the maintenance of the myelin sheath that protects nerve cells. Additionally, histidine is a precursor for the synthesis of histamine, which is involved in various physiological processes such as digestion, immune response, and inflammation. It also acts as a metal chelator, binding with heavy metals to aid in their excretion from the body. Histidine is found in various protein-rich foods such as meat, fish, dairy products, and certain grains, making it an important nutrient for overall health and well-being.

Check Digit Verification of cas no

The CAS Registry Mumber 71-00-1 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 7 and 1 respectively; the second part has 2 digits, 0 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 71-00:
(4*7)+(3*1)+(2*0)+(1*0)=31
31 % 10 = 1
So 71-00-1 is a valid CAS Registry Number.

An unprecedented trans-oriented product from the cleavage of a dipeptide.

Saha, Manas K,Bernal, Ivan

, p. 612 - 613 (2003)

An unusual trans cleavage reaction was observed when trans-[Co(3,2,3-tet)Cl2]Cl (3,2,3-tet = N,N'-bis(3-aminopropyl)ethylenediamine), was allowed to react with beta-alanyl-L-histidine (a bioactive dipeptide) in an aqueous medium at pH approximately 7.5 and 45 degrees C for 6 h.

Direct monitoring of biocatalytic deacetylation of amino acid substrates by1H NMR reveals fine details of substrate specificity

De Cesare, Silvia,McKenna, Catherine A.,Mulholland, Nicholas,Murray, Lorna,Bella, Juraj,Campopiano, Dominic J.

supporting information, p. 4904 - 4909 (2021/06/16)

Amino acids are key synthetic building blocks that can be prepared in an enantiopure form by biocatalytic methods. We show that thel-selective ornithine deacetylase ArgE catalyses hydrolysis of a wide-range ofN-acyl-amino acid substrates. This activity was revealed by1H NMR spectroscopy that monitored the appearance of the well resolved signal of the acetate product. Furthermore, the assay was used to probe the subtle structural selectivity of the biocatalyst using a substrate that could adopt different rotameric conformations.

Safe and Effective Method of Treating Ulcerative Colitis with Anti-IL12/IL23 Antibody

-

, (2020/04/10)

Described are methods and compositions for clinical proven safe and effective treatment of ulcerative colitis, particularly moderately to severely active ulcerative colitis in patients who have had an inadequate response to or are intolerant of a conventional or existing therapy by intravenous and/or subcutaneous administration of an anti-IL-12/IL-23p40 antibody.

Preparation and characterization of a new open-tubular capillary column for enantioseparation by capillary electrochromatography

Li, Yingjie,Tang, Yimin,Qin, Shili,Li, Xue,Dai, Qiang,Gao, Lidi

, p. 283 - 292 (2019/02/05)

In order to use the enantioseparation capability of cationic cyclodextrin and to combine the advantages of capillary electrochromatography (CEC) with open-tubular (OT) column, in this study, a new OT-CEC, coated with cationic cyclodextrin (1-allylimidazolium-β-cyclodextrin [AI-β-CD]) as chiral stationary phase (CSP), was prepared and applied for enantioseparation. Synthesized AI-β-CD was characterized by infrared (IR) spectrometry and mass spectrometry (MS). The preparation conditions for the AI-β-CD-coated column were optimized with the orthogonal experiment design L9(34). The column prepared was characterized by scanning electron microscopy (SEM) and elemental analysis (EA). The results showed that the thickness of stationary phase in the inner surface of the AI-β-CD-coated columns was about 0.2 to 0.5?μm. The AI-β-CD content in stationary phase based on the EA was approximately 2.77?mmol·m?2. The AI-β-CD-coated columns could separate all 14 chiral compounds (histidine, lysine, arginine, glutamate, aspartic acid, cysteine, serine, valine, isoleucine, phenylalanine, salbutamol, atenolol, ibuprofen, and napropamide) successfully in the study and exhibit excellent reproducibility and stability. We propose that the column, coated with AI-β-CD, has a great potential for enantioseparation in OT-CEC.
