Free radical 5-exo-dig cyclization as the key step in the synthesis of bis-butyrolactone natural products: experimental and theoretical studies [PDF]
, 2011 Radical cyclization reactions were performed by 5-exo-dig mode to yield cis-fused bicyclic systems, leading to the synthesis of bis-butyrolactone class of natural products.

Dependence of folding rates on protein length [PDF]
, 2002 Using three-dimensional Go lattice models with side chains for proteins, we investigate the dependence of folding times on protein length. In agreement with previous theoretical predictions, we find that the folding time grows as a power law with the ...

Out of Equilibrium Characteristics of a Forced Translocating Chain through a Nanopore [PDF]
, 2010 Polymer translocation through a nano-pore in a thin membrane is studied using a coarse-grained bead-spring model and Langevin dynamics simulation with a particular emphasis to explore out of equilibrium characteristics of the translocating chain.

Preparation of Benzalkonium Salts Differing in the Length of a Side Alkyl Chain
Molecules, 2007 Benzalkonium salts are widely used as disinfectants, biocides and detergents,among a variety of other applications. The cationic surface-activity of these saltsdetermines their potential to act as a biocide on both target and non-target organisms. Inthis

Hydrophobically modified polyelectrolytes as potential drugs reservoirs of n-alkyl-nitroimidazoles [PDF]
, 2007 Indexación: ScieloThe solubilization of three commercial drugs (ornindazole, metronidazole and tinidazole) and model compounds (N-alkyl-2-methyl-4-nitroimidazoles) on aggregates formed by anionic polyelectrolytes, carrying alkyl side chains of different ...

Extensin arabinoside chain length is modulated in elongating cotton fibre
The Cell Surface, 2019 Cotton fibre provides a unicellular model system for studying cell expansion and secondary cell wall deposition. Mature cotton fibres are mainly composed of cellulose while the walls of developing fibre cells contain a variety of polysaccharides and ...

Dynamics of end-pulled polymer translocation through a nanopore [PDF]
, 2017 We consider the translocation dynamics of a polymer chain forced through a nanopore by an external force on its head monomer on the trans side. For a proper theoretical treatment we generalize the iso-flux tension propagation (IFTP) theory to include ...

Biological significance of the side chain length of ubiquinone in Saccharomyces cerevisiae [PDF]
FEBS Letters, 1998 Ubiquinone (UQ), an important component of the electron transfer system, is constituted of a quinone structure and a side chain isoprenoid. The side chain length of UQ differs between microorganisms, and this difference has been used for taxonomic study.
