Examplesofnon-polarnon-polar This review further outlined thenon-polarand electrostatic contributions of the solvation free energy. From theCambridge English Corpus This includes, in particular, polar solvents like ammonia, hydrocyanic acid, and methanol, and possiblynon-polarcompounds such as methane and ethane. From theCambridge English Corpus Included are a number of incidents - or viewpoints about them - that are perhaps less familiar to thenon-polarspecialist. From theCambridge English Corpus However, there do exist a number of basespecific contacts, includingnon-polarcontact of the 5-methyl group of thymidine in the major groove. From theCambridge English Corpus Selective permeability to polar andnon-polarsubstances in fertilized eggs is a function of the lipid membrane layer. From theCambridge English Corpus For the simulations with and without urea the solvent accessible surface area of polar andnon-polargroups were very similar. From theCambridge English Corpus The heptane had no effect in removing the membrane, implying that the vitelline membrane may not be made up ofnon-polarlipids. From theCambridge English Corpus The entropy change of hydration of polar andnon-polargroups are both positive on folding and so drive the folding process. From theCambridge English Corpus Amphipathic molecules have a polar, hydrophilic head group region and anon-polar, hydrophobic part. From theCambridge English Corpus The genetic information must replicate efficiently and reliably, using nucleotide monomers that could diffuse through thenon-polarlipid protocell membrane. From theCambridge English Corpus A hydrophobic surface is one that isnon-polarand inert to water in the sense that it cannot bind to water molecules via ionic or hydrogen bonds. From theCambridge English Corpus It is interesting to compare the partitioning of polar andnon-polarsidechains in these systems because only one face of the -hairpin interacts with the remainder of the protein. From theCambridge English Corpus However, most of the calculations that have appeared to support mechanisms of this type have assumed that the reactants have the same energy in polar andnon-polarenvironments. From theCambridge English Corpus The conductivity is due to that the main carbon chain separates from the side chains, thus forming polar andnon-polarregions.
