Effect of intramuscular fat content on the meat quality and antioxidative dipeptides
of Hanwoo beef.
Carnosine and related dipeptides
as quenchers of reactive carbonyl species: from structural studies to therapeutic perspectives.
First, isolated and characterized in 1900 by Gulewitsch, carnosine ([beta]-alanyl-L-hystidine) is a dipeptide
, which commonly presents in mammalian tissue, and in particular, in skeletal muscle cells; it is responsible for a variety of activities related to the detoxification of the body from free radical species and the byproducts of membrane lipids peroxidation, but recent studies have shown that this small molecule also has membrane protecting activity, proton buffering capacity, formation of complexes with transition metals, and regulation of macrophage function (6).
Instability index is a measure of protein stability in vitro, calculated by the occurrence of 400 dipeptides
in the protein sequence (Guruprasad et al.
Free amino acids and dipeptides
in porcine muscles: differences between 'red' and 'white' muscles.
32) Both carnosine and anserine are antioxidative histidyl dipeptides
and the most abundant antioxidants in meat.
Potassium bindings to dipeptides
and corresponding structures were determined theoretically by Wong et al.
also resulted in differences in growth patterns between the flhD and fliA mutants and the wild type Yersinia.
EZ:faast LC/MS kits from Phenomenex have been developed for the analysis of more than 60 aliphatic and aromatic amino acids, dipeptides
and related compounds in just under 20 minutes.
It preferentially cleaves dipeptides
from the amino terminus of peptides with a proline or alanine in the second position.
It is known that substrates containing the dipeptides
His-Leu or Gly-Gly in their terminal portions are cleaved by ACE (Yang et al.
