Figure 2: Formation of a polypeptide by reaction of amino acids. (R , R and R may be the same or different 1 2 3 side groups). These contaminants are removed during processing. Clean wool, together with other animal fibres, belongs to a group of proteins known as keratins. Unlike cotton and the majority of synthetic fibres, wool does not have a homogeneous structure. Wool fibres have highly com...

Control structure design deals with the structural decisions of the control system, including what to control and how to pair the variables to form control loops. Although these are very important issues, these decisions are in most cases made in an ad hoc fashion, based on experience and engineering insight, without considering the details of each problem. In the paper, a systematic procedure ...

Since its public introduction in 2005 the IUPAC InChI chemical structure identifier standard has become the international, worldwide standard for defined chemical structures. This article will describe the extensive use and dissemination of the InChI and InChIKey structure representations by and for the world-wide chemistry community, the chemical information community, and major publishers and...

We consider the low temperature ordered phases discrete model with nondegenerate periodic ground of general classical statistical mechanical models, state. A small change in the external conditions could allowing several species of structureless particles not produce such a local effect in the ground state; as interacting through translation invariant, short range long as the period remains bou...

NMR spectroscopy plays a major role in the determination of the structures and dynamics of proteins and other biological macromolecules. Chemical shifts are the most readily and accurately measurable NMR parameters, and they reflect with great specificity the conformations of native and nonnative states of proteins. We show, using 11 examples of proteins representative of the major structural c...

Systematic chemical studies indicate that the capability of Watson-Crick base-pairing is widespread among potentially natural nucleic acid alternatives taken from RNA's close structural neighborhood. A comparison of RNA and such alternatives with regard to chemical properties that are fundamental to the biological function of RNA provides chemical facts that may contain clues to RNA's origin.

This review summarizes studies concerning the covalent binding of [14C]TCE to rat liver microsomal protein and exogenous DNA, in vitro, the enhancement of this binding by inducers of mixed-function oxidases, and inhibition of binding by inhibitors of these enzymes. Furthermore, recent studies on this type of binding in various strains of mice and rats of both sexes and using microsomal preparat...

Acknowledgements This thesis represents the work I have carried out as a PhD student under the supervision of Professor Jan H. Jensen in his group of Biocomputational Chemistry. Thank you to all who have supported me during my work at the third floor of C-building at the H.C. Ørsteds Institute. I would especially like to thank the following people: • Thank you to my supervisor, Jan " Yoda " Jen...
