group (CEG) content in the samples was determined by titrating a solution of the PET and PET nanocomposites in o-cresol/dichloro methane according to the ASTM D7409-07.
Alpha-helices are green cylinders; arrows point from the free amino end to the free carboxyl end
To overcome this limitation on subunit assembly, the FSH heterodimer was converted to a single chain by genetically fusing the carboxyl end
of the FSH [beta] subunit to the amino end of the a subunit by a carboxyl-terminal peptide (CTP) linker sequence (Sugahara et al.
Equations (1) and (2) are dynamic material balances on amine end groups (A), carboxyl end
groups (C) and water (W) in the molten polymer phase.
Moisture attacks the carboxyl end
group of the polymeric chain, causing chain cleavage and decomposition.
None of these were in the transmembrane region sequence (482-502 aa) or in the intracytoplasmic region sequence (503-530, the carboxyl end
of the protein).
It has a relatively low level of carboxyl end
groups; thus, says Ticona, it has good hydrolytic stability, providing buffer tubes resistance to high heat and humidity.
The number following the delta sign indicates the location of the double bonds, counting from the carbon at the carboxyl end
of the fatty acid, (the right side of the chains in [ILLUSTRATION FOR FIGURE 1 OMITTED]) which is designated as the number 1 carbon.
In this article we will report on the result of an examination of the fatigue behavior of PET fibers having a relatively high molecular weight and different carboxyl end
groups, when spin-drawn and heat treated under conditions similar to those used in the cord-dipping process, which is essential in tire cord production.
24 ppm; carboxyl end
groups show a peak at [delta]: 167.
Then products with containing carboxyl end
group were obtained (Reaction 6).
Depolymerization products containing hydroxyl and carboxyl end
groups were obtained at the end of the reactions.
