Its utility has increased due to the simplified sample preparation for biological samples, when analyzing for metabolites, since the metabolic process generally results in the addition of polar groups to enhance elimination from the cellular tissue.

The resulting overlay shows that only the C2 C3 ligands are able to adopt a conformation in which the polar group of the 3?-substituent occupies the position proximal to that of the 2?-polar group in WIN35428.

Given that plasma polymers frequently contain many polar groups, which form when the radicals react with oxygen in air during the polymerization process, the plasma polymers were expected to be good dielectric materials in thin film form.

Sherman and Smith received on April 13, 1971, for " invention of block and graft copolymers containing water-solvatable polar groups and fluoroaliphatic groups . " Sherman holds 13 patents with Smith in flurochemical polymers and polymerization processes.

On the other hand, analytes with higher polar surface area ( conferred by the presence of polar groups, such as-OH,-NH 2, COO " or-NH 3 + in their structure ) are less retained as they are better integrated into water.

Materials containing polar groups, aromatic systems, and double and triple bonds tend to appear darker than non-polar fully saturated substances; when a water-clear appearance is desired, suitable polymers and additives, e . g . hydrogenated tackifying resins, have to be used.

?-Helices are also the most common protein structure element that crosses biological membranes ( transmembrane protein ) it is presumed because the helical structure can satisfy all backbone hydrogen-bonds internally, leaving no polar groups exposed to the membrane if the sidechains are hydrophobic.

The South Polar group, compared of Shirase and six other men, traversed the Ross Ice Shelf, reaching a farthest south point at 80?'S, 156?7'E on 28 January 1912, claiming all of the Ross Ice Shelf for Japan as Yamato Yukihara ( lit . " The Japan Snow Plain " ).

Valentine has proposed that Ojibwe dialects are divided into three groups : a northern tier consisting of Severn and Algonquin; a southern tier consisting of " Odawa, Chippewa, Eastern Ojibwe, the Ojibwe of the Border Lakes region between Minnesota and Ontario, and Saulteaux; and third, a transitional zone between these two polar groups, in which there is a mixture of northern and southern features ."
