symposium begins with a general lecture on the structure of fibrous proteins by G. N. Ramachandran (32 pages) and is then divided into three parts which contain papers on, respectively, the structure of collagen, the chemistry and metabolism of collagen, and the physical chemistry of variously modified collagens. It should be stated at the outset that this book will not fill the need of the bio...
Density functional theory study of the conformational space of an infinitely long polypeptide chain.
The backbone conformational space of infinitely long polyalanine is investigated with density-functional theory and mapping the potential energy surface in terms of (L, theta) cylindrical coordinates. A comparison of the obtained (L, theta) Ramachandran-like plot with results from an extended set of protein structures shows excellent conformity, with the exception of the polyproline II region. ...
in this paper we prove existence the common fixed point with different conditions for $alpha-psi$-contractive mappings. and generalize weakly zamfirescu map in to modified weakly zamfirescu map.
