The energies of oligopeptide segments of lysozyme are minimized with respect to the dihedral angles of the central residue. As the length of the oligopeptide segment increases, up to a nonapeptide, the low-energy conformation becomes that observed in the x-ray structure in most cases. This finding suggests that, while short-range interactions appear to play the dominant role in determining the ...

Parasitic chytrid fungi (phylum Chytridiomycota) are known to infect specific phytoplankton, including the filamentous cyanobacterium Planktothrix. Subspecies, or chemotypes of Planktothrix can be identified by the presence of characteristic oligopeptides. Some of these oligopeptides can be associated with important health concerns due to their potential for toxin production. However, the relat...

This photophysical study characterizes the generality of intermolecular electronic interactions present within nanomaterials derived from self-assembling oligopeptides with embedded π-conjugated oligophenylenevinylene (OPV) subunits stilbene and distyrylbenzene that in principle present two distinct β-sheet motifs. Two different synthetic approaches led to oligopeptides that upon self-assembly ...

The literature review is devoted to biologically active metabolites of casein — the results its hydrolysis oligopeptides casomorphins. These peptides with a chain length 4 11 amino acids are derived from milk β-casein and released during digestion, both in vivo vitro. Caseomorphins exhibit opioid pharmacological activity due binding μ-receptors located central nervous system, gastrointestinal t...

Age-and sex-dependent characteristics of Mediterranean horse mackerel Trachurus mediterraneus from Sevastopol coastal waters (Black Sea, Ukraine) at the period of 2008-2010 were studied. The alaninand aspartataminotransferase (ALT and AST) activities in the liver and oligopeptides concentration in blood were measured in male and female at the age of 1-3 years. Significant age-dependent changes ...
