When hydrogen ion concentration is determined by the catalytic method, the hydrogen ions are permitted to react with a neutral molecule (inversion of sugar cleavage of diazoacetic acid... [Pg.81]

The base-specific chemical cleavage (or Maxam-Gilbert) method starts with a single-stranded DNA that is labeled at one end with radioactive (Double-stranded DNA can be used if only one strand is labeled at only one of its ends.) The DNA strand is then randomly cleaved by reactions that specifically fragment its sugar-phosphate backbone only where certain bases have been chemically removed. There is no unique reaction for each of the four bases. However,... [Pg.360]

Note that the key to Maxam-Gilbert sequencing is to modify a base chemically so that it is removed from its sugar. Then piperidine excises the sugar from its 5 - and 3 -links in a /3-elimination reaction. The conditions of chemical cleavage described in Figures 12.4 and 12.5 are generally adjusted so that,... [Pg.361]

The use of this group was developed to improve the quality and mildness of the cleavage reaction in the synthesis of complex amino sugars.The dichloroph-thalimide group has also been examined in this context, but little is known of its advantages or disadvantages. ... [Pg.566]

To gain an insight into the likely hydrolytic behavior of sulfated simple sugars and polysaccharides, Brimacombe, Foster, Hancock, Overend, and Stacey carried out a rigorous set of experiments with the cyclic sulfates of cyclohexane cis-and trims-1,2-diol as model compounds. The results were interpreted on the reasonable assumption that, in all cases, the cyclic sulfates initially afford a diol monosulfate. Examples of both S-0 and C-0 bond cleavage were encountered. A qualitative reaction mechanism was proposed for use as a working hypothesis for the hydrolysis of sugar sulfates. [Pg.16]
