Approaches to the Enzymatic Carbohydrate Synthesis

Abstract

Polysaccharides are the least appreciated class of macromolecules though they constitute the largest part of the planet's bio-mass. This large bulk has perpetuated a compelling reason for their neglect: carbohydrates were thought to be biochemically uninteresting serving as structural and energy storage molecules. The second more insidious and perhaps contradictory reason for the relative slowness in carbohydrate research is that biochemically important carbohydrates are difficult to study. They seem haphazardly put together, without a template, creating enormous complexity that, at first, did not suggest specific functions. The past three decades have seen enormous strides in the understanding of the importance of carbohydrates feeding the quickly expanding and vibrant field of enzymatic carbohydrate synthesis. The clear goal of the research in this field is to supplant Nature as the supreme oligosaccharide maker to generate desired saccharides, be it natural or unnatural, in high yields, large quantities and at low cost.

Seed Displacement, Epitaxial Synthesis of Rh/Pt Bimetallic Ultrathin Nanowires for Highly Selective Oxidizing Ethanol to CO2

“…Many Pt-based alloys such as Pt/Ru, Pt/Rh, Pt/Sn and Pt/Rh/Sn have been widely investigated. [48][49][50][51][52][53][54][55] The results have showed the alloy boosted up the ethanol oxidation owing to their unique surface structure and electron interaction. However, the limited successes were achieved for highly selective oxidizing ethanol to CO 2 .…”
