Suitable oxyalkylating agents include ethylene oxide, propylene oxide, butylene oxide and glycid, which, although not included, strictly speaking, by the unitary structure CnHznO, is included within the meaning of the hereto appended claims and may be simply considered as a variant of propylene ...
Any of a class of organic compounds in which two hydrocarbon groups are linked by an oxygen atom. Ester (organic compound) A compound most often formed by the condensation of an alcohol and an acid, with elimination of water, which contains the functional group carbon-oxygen double bond (i....
Surprisingly, however, it was found that, by adhering to certain structure parameters for the polymethacrylate esters that are to be reacted and to a suitable selection of process conditions during the transesterification, it is possible to transesterify one or both of the terminally linked ester ...
Amino acids and peptides can be linked together enzymatically with the aid of thermolysin or chymotrypsin when one amino-acid residue is proteinogenous and the other amino-acid residue is non-proteinogenous. R Keller,W Muller - EP 被引量: 23发表: 1989年 Eine neues Verfahren zur Peptidsynthes...
two or three aromatic or heteroaromatic rings which are linked to one another directly or via one or two COO groups; B denotes a chemical bond or one or two aromatic or heteroaromatic rings which are linked directly to one another; R2 (a) if B is a chemical bond, denotes an alkyl radic...
” He’s hardly the first intellectual to fall into the tar pit of generalizing from his own experiences. But it’s a disturbingly prevalent trend among white male taste-makers: assuming that what they relate to and find meaning in, the rest of us must as well, AND that those books ...
cell lines despite low doses of DOX applied and good compatibility with normal cells. Research confirms the effect of PNPs on the degradation of the biological membrane, and the accumulation of reactive oxygen species (ROS), and the ability to cell cycle arrest are strictly linked to cell ...
Dextran is a hydrophilic, non-immunogenic polysaccharide composed of α-1,6-linked d-glucopyranose; it can be branched with α-linked glucose moieties from any of its secondary hydroxyl groups, depending on the bacterium that produces that particular dextran (Naessens et al., 2005). Linear (...
Notably, in the original meaning, the ‘disarmed’ unit of product 6 could be changed to an ‘armed’ entity so as to readily serve as a glycosyl donor.16 The deactivating effect of esters versus ether protecting groups upon sugars had been noted in Paulsen’s article.1 But the first demo...
