Structural Analysis of Glycosylated Peptides in Complex Mixtures with Ion Trap MSn

... in mass following cleavage is used to infer the carbohydrate constituents of the cleaved glycoform. Generally, neither the oligosaccharide structure nor the exact site of attachment to the peptide can be determined. This technique is labor-intensive, time-consuming, and it requires a large am...

Anti-ethanol arguments are easily debunked

... for the first time, economically convert soy meal carbohydrate into ethanol. I'm a believer, and I have a vested interest. The first anti-ethanol argument - one that is so old it is hardly worth mentioning, but one that comes up in every ethanol debate - is the energy balance issue. The argument is that ethanol...

Existing treatments use carbohydrate targeting molecules that are stripped away in the liver, Broderick said, while ZyStor will use proteins, which are expected to survive longer and deliver more enzymes. One of the conditions ZyStor will tackle is Pompe disease , which Broderick esti...

... and health can be assured by eliminating the evil carbohydrate from their diets. In the 1980s they thought the exact opposite good health and proper weight would accrue from eliminating all fat and replacing it with healthy oat brand and other carbohydrates. But instead of thinning the nation, we fattened it up...
