As has been shown by Fisher1, the knowledge of the amino-acid composition permits in many cases the tertiary and sometimes the quaternary structure of the proteins to be predicted. The ratio of the polar and non-polar amino-acids seems to be a very important characteristic of the protein. ...

The ratio of the polar and non-polar amino-acids seems to be a very important characteristic of the protein. The change of the relative numbers of the polar and non-polar amino-acids as a result of a mutation must produce big changes in the protein structure. The mutational exchange of a...
Methionine is one of the 20 normal amino acids that make up proteins. It is a very important part of the light code, starting with how proteins are made. Methionine is a special type of amino acid. It has sulfur in it and its chemical formula is C5H11NO2S. To know if it's positiv...

9) and molecular structures of the polar amino acids (Fig. 1), the non-charged H-donating amino acids (Ser, Thr, Cys, Lys, Arg) and the amino acids with amide functions (Asn, Gln) indeed showed greater ACC stabilization than negatively charged Cys, Asp, Glu and Tyr. The only ...
The interactions may be broadly ionic or non-ionic (polar or non-polar) in nature. An ion immobilizes water in oriented layers surrounding the charge centre. For example, the higher the amount of available polar amino acids in a food system, the larger the volume of bound water. Non-...
The stability of globular proteins arises largely from the burial of non-polar amino acids in their interior. These residues are efficiently packed to eliminate energetically unfavorable cavities. Contrary to these observations, high resolution X-ray crystallographic analyses of four homologous lipases ...

Guanine exist in the gas phase as the canonical keto-amino tautomer, the enol tautomer being around 1 kcal/mol less stable [118-120]. Such a difference is expected to be much larger in aqueous solution [121], which precludes any important biological role for the non-canonical tautomers of...
