Lysine (symbol Lys or K) [2] is an α-amino acid that is a precursor to many proteins.Lysine contains an α-amino group (which is in the protonated −NH + 3 form when the lysine is dissolved in water at physiological pH), an α-carboxylic acid group (which is in the deprotonated −COO − form when the lysine is dissolved in water at physiological pH), and a side chain (CH 2) 4 NH 2 (which ...
In computational biology, protein pK a calculations are used to estimate the pK a values of amino acids as they exist within proteins.These calculations complement the pK a values reported for amino acids in their free state, and are used frequently within the fields of molecular modeling, structural bioinformatics, and computational biology.
A hydrophilicity plot is a quantitative analysis of the degree of hydrophobicity or hydrophilicity of amino acids of a protein.It is used to characterize or identify possible structure or domains of a protein.
N.D.: The pKa value of Pyrrolysine has not been reported. Note: The pKa value of an amino-acid residue in a small peptide is typically slightly different when it is inside a protein. Protein pKa calculations are sometimes used to calculate the change in the pKa value of an amino-acid residue in this situation.
This phenomenon is based on the interaction between the positively charged polymer and negatively charged cells or proteins. While the poly-L-lysine (PLL) precursor amino acid occurs naturally, the poly-D-lysine (PDL) precursor is an artificial product. The latter is therefore thought to be resistant to enzymatic degradation and so may prolong ...
Scientists thought that Lake Enigma was frozen from top to bottom. Then they discovered that water—and mysterious lifeforms—existed 11 meters below the surface.
Lisdexamfetamine is a substituted amphetamine with an amide linkage formed by the condensation of dextroamphetamine with the carboxylate group of the essential amino acid L-lysine. [19] The reaction occurs with retention of stereochemistry, so the product lisdexamfetamine exists as a single stereoisomer.
