(salt bridges), and covalentdisulfidebridges formed between cysteine residues. These interactions build upon theprimary(amino acidsequence) andsecondary(alpha helices and beta pleated sheets) structures, leading to a fully functional protein. Understanding these structures is crucial for grasping prote...
Created using AI Polymers exhibit varying degrees ofcrystallinity, which significantly influence their strength, density, and thermal properties. Crystallinity arises from strong intermolecular forces and specificstereochemistry, withisotacticstructures being the most crystalline. Key thermal properties inc...
Specifically, we discuss the theoretical and instrumental background of continuous-wave and pulse high-field EPR and the multiple-resonance extensions EDNMR, ENDOR, TRIPLE, ESEEM, PELDOR, and RIDME. Some emphasis is placed on a balanced description of both the historical spadework and the ...
It collects and archives the 3D-atomic level structural models of these macromolecules obtained through three commonly used experimental techniques: crystallography, nuclear magnetic resonance spectroscopy (NMR), and electron microscopy (3DEM). The database entries are mostly structures of proteins, althoug...
The identity of S25DH products was confirmed by LC-MS and NMR (Table S4, Fig. S10–13 of Supplementary Material) and was consistent with that to reported before (Chiang et al. 2007; Warnke et al. 2016). Electrochemical recovery of S25DH re-oxidant During the reaction, S25DH is reduced...

Structure determination is a critical analytical skill involving the synthesis of data from molecular formulas, NMR, and IR spectra to deduce molecular structures. Begin by calculating the Index of Hydrogen Deficiency (IHD) to identify unsaturation. Analyze NMR shifts, integrations, and splittin...
19. Reactions of Aromatics: EAS and Beyond Topic summary Created using AI Benzene can undergonucleophilic aromatic substitution(SNAR) in the presence of strong nucleophiles, leading to an anionicsigma complex. This two-stepreactioninvolves an initial nucleophilic attack followed byelim...
high precision in controlling the size and position of nanoscale features. Using femtometer-scale measurements, researchers can achieve nanometer-level accuracy in processes like electron beam lithography or scanning probe microscopy, facilitating the creation of advanced nanoscale devices and structures. ...
