997-20-6 Usage
General Description
LYS-LYS-LYS-LYS is a synthetic peptide composed of four repeating units of the amino acid lysine. Lysine is an essential amino acid that plays a critical role in protein synthesis and is important for the growth and maintenance of tissues. The repetitive nature of the peptide sequence suggests that it may have potential applications in biomaterials, drug delivery, or as a template for creating new materials with specific properties. The presence of multiple lysine residues in the sequence also suggests that it may have potential for use as a cell-penetrating peptide or in the development of antimicrobial agents. Overall, LYS-LYS-LYS-LYS has the potential to be a versatile and valuable tool for biomedical and materials science research.
Check Digit Verification of cas no
The CAS Registry Mumber 997-20-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 997-20:
(5*9)+(4*9)+(3*7)+(2*2)+(1*0)=106
106 % 10 = 6
So 997-20-6 is a valid CAS Registry Number.

Modelling of prebiotic synthesis and selection of peptides under isothermal conditions and thermal cycling mode
Demina,Kononikhin,Laptev,Khodonov,Nikolaev,Varfolomeev
, p. 422 - 441 (2013/06/27)
The model peptide synthesis from mixtures of amino acids was carried out under the thermal cycling and isothermal modes. The compositions of the obtained mixtures of products and the primary amino acid sequence of the synthesized peptides were determined by Fourier transform ion cyclotron resonance mass spectrometry and tandem mass spectrometry in combination with high-performance liquid chromatography with the application of de novo sequencing of the synthesized products. The processes of abiogenous synthesis of peptides were shown to occur under relatively mild temperature conditions and give a substantially less number of peptides as compared with the possible statistical set. The evolution of the system takes place in the process of the synthesis in solid phase with the disappearance of a series of the most unstable peptides. The selection process with the formation of complementary peptides takes place in peptide synthesis under the thermal cyclic mode.
