Long memory in spatial series of model peptides on the basis of
glycine and alanine
Abstract
Spatial series based on histogram of
interatomic distances are investigated using the methods of detrended
fluctuation analysis and rescaled range analysis. Glycine and alanine model
peptides were used as objects of study. The effect of monomer type, chain
length and conformation on the values of the Hurst coefficients is analyzed. In
general, it can be stated that the majority of the studied spatial series
exhibit persistent behavior, i.e. have a long-term memory.
Key words: peptides, Hurst parameter, DFA, R/S analysis.
