Peptide primary

Literature on the cause and control of the flavor of crackers is scant. Faridi and Johnson (10) studied the chemical changes related to flavor precursor components (organic and amino acids) during the twenty-five hour fermentation period. They measured the total soluble nitrogen, peptides, primary amines, and ammonia formed in cracker doughs as a result of the lengthy fermentation. All components increased...

A particularly interesting feature of these hybrid block copolymers is that the aggregation number and pH sensitivity of the nanoobjects can be controlled via direrted single and double mutations of the peptide primary structure. This may be relevant in light of possible biomedical applications because preliminary experiments have shown that the biological properties of the PEGylated coiled coils correlate to their self-assembly behavior. Another example that is worth mentioning is the work by Velonia et who studied the...

With regard to its electronic properties, no studies are available that clearly demonstrate that electron transfer through such a supramolecular assembly is possible. Solid-state electrochemical studies on the crystalline material are not available at the present time. The closest to supramolecular electrochemistry are studies of ordered two-dimensional peptide arrays on gold. For some Fc-peptide cystamines, self-assembled monolayers of Fc-peptide cystamines were prepared that allow the quantification of the electron transfer kinetics by electrochemical techniques. Similar to the supramolecular assemblies, H-bonding plays an important role. At the present time (2003), only a few systems were studied and offer a rather complex picture of the ET properties. Additional experimental work is required to obtain definite results on the influence of the peptide primary and secondary structure on ET kinetics. In addition, tile issue of lateral interactions needs to be addressed by detailed dilution studies with alkylthiols.
