Acids and bases neutralize each other because excess hydrogen ions combine with excess hydroxide ions to form water. These neutralization reactions also form various salts. For example, hydrochloric acid reacts with sodium hydroxide to produce water and sodium chloride, common table salt. ...
Hard and Soft Acids and Bases (HSAB) Theory 30 2 Basic Concepts In the chapters below the chemistry, upon which the collected works in this thesis are built, is explained. The theories and definitions described herein are vital for coordination chemistry, but should not be taken as full ...
and 8; Supplementary Tables6and7). Various solvents were then screened; the use of mesitylene improved the yield to 94%, but the enantioselectivity decreased slightly (Table1, entry 9 and Supplementary Table8). Mesitylene was used as the solvent in the further screening of the bases and ...
(i.e.PDIBJarea; the protein-DNA interface formed by amino acids of helix B and J and nucleotides 10/66, 11/65, and 12/64) is zoomed in, and relevant bases and amino acids are labeled. The numbering used is based on the Cre/loxPcrystal structure (for details see Fig.S1). Figure ...
IPD currently consists of four data- bases: IPD-KIR, contains the allelic sequences of Killer-cell Immunoglobulin-like Receptors; IPD- MHC, a database of sequences of the Major Histocompatibility Complex of different species; IPD-HPA, alloantigens expressed only on platelets; and IPD-ESTAB, ...
Using DFT calculations, different parameters like zero-point energy, thermal energy, thermal enthalpy andfree energyfor the designed amino-acids have been determined to know about their stability as inTable 1. Based on the results obtained in theTable 1, zero-point energy, thermal energy, thermal...
Full size table Next, we applied our protocol to the synthesis of α,α-disubstituted α-amino acids, which are distinguished by their restricted conformational flexibility, increased lipophilicity and metabolic stability, as well as increased resistance towards racemization37,38. Most existing synthetic...
While flow technology has provided a partial answer to these safety challenges38, a truly general and practical alternative for such transformation has been elusive39. Indeed, polar variants such as the Kowalsky Ester homologation suffer from the use of organolithium bases, strongly limiting the ...
