L-Threose is a significant degradation product of ascorbic acid at pH 7.0 in the presence of oxygen. When compared to several other ascorbate-derived degradation products, it had the greatest ability to glycate and crosslink lens proteins in vitro. To determi...

A supported liquid membrane (SLM) containing a resorcinarene carrier has been used for the selective transport of erythritol, threitol, ribitol and xylitol from concentrated (1.0-0.01 M) aqueous solutions. The membrane is made of a microporous polytetrafluoro...

Differently protected erythro and threo furanoid glycals were synthesized by selenoxide elimination when phenyl 1-selenoglycosides were treated in oxidizing conditions (tBuOOH, Ti(O(i)Pr)(4), Et(2)(i)PrN). The phenyl 1-selenoglycosides were obtained from meth...

Dithiothreitol (DTT) is widely used to reduce disulfide bonds in the analysis of protein structure and function. However, thiol-disulfide exchange is not the only mechanism whereby DTT can alter protein function. We observe that DTT diminishes the carbohydrat...

The inhibition of the metalloenzyme carbonic anhydrase (CA, EC 4.2.1.1) with dithiothreitol, 2-mercaptoethanol, tris(carboxyethyl)phosphine (reducing agent frequently added to enzyme assay buffers) and threitol has been investigated. The agents were very weak...
