Definition D-amino acids are α-amino acids that have the R configuration at their α-carbon atom, with the exception of cysteine, which is of the L configuration. D-amino acids are produced by enzymatic post-translational modification of the isomeric L-amino acids which are ribosomally encoded...
A method for amino acid sequence and ja:math configuration identification of peptides by using fluorogenic Edman reagent 7-[( N,N -dimethylamino)sulfonyl]-2,1,3-benzoxadiazol-4-yl isothiocyanate (DBD-NCS) has been developed. This method was based on the Edman degradation principle with some ...
These isoforms differ by the configuration of a single amino acid residue, Phe3 (phenylalanine in position 3 from the N-terminus of the peptide) [13]. When administered to the lobsters, the D-phenylalanine-containing peptide showed a delayed effect on the glucose level in the hemolymph ...

Anyhow, D-configuration of serine is the structural element that maintains the phalloidin-like structure, while the hydroxy group does not contribute to conformational stability but is likely to be in contact with the actin surface. 展开 关键词: Animals Rabbits Peptides, Cyclic Phalloidine Actins ...
DefinitionChEBI: D-ribose is a ribofuranose having D-configuration. It is a naturally occurring monosaccharide found in the cells and particularly in the mitochondria is essential in energy production. Biological FunctionsD-ribose is a penta-sugar precursor of some amino acids like glutamate, histidine...

The amino alcohol, including its absolute configuration, was determined by labelling with (+)-MNB-COOH, and the dipeptide was reused for a determination of its C-terminal amino acids. The d,l-amino acids of the tripeptide were sequentially determined from the C-terminus....
L‐amino acidstoxicityWhile the L -configuration of amino acids predominates in all known living systems, D -enantiomers of amino acids have been detected with highly sensitive chromatographic techniques in human physiological fluids. In the present study, the survival of Chinese hamster ovary cells ...
