Type II diabetes and pre-diabetes are widely prevalent among adults. Elevated serum glucose levels are commonly treated by targeting hepatic gluconeogenesis for downregulation. However, direct measurement of hepatic gluconeogenic capacity is accomplished only via tracer metabolism approaches that rely on

1. The structures of the alpha(2)- and alpha(3)-azopigments, prepared by diazotization of dog bile with ethyl anthranilate, were shown by mass spectrometry and g.l.c. to correspond to azobilirubin beta-d-xylopyranoside and azobilirubin beta-d-glucopyranoside respectively. 2. Both azopigments consist of a mixture

S-adenosylmethionine (SAM) is the methyl-donor substrate for DNA and histone methyltransferases that regulate epigenetic states and subsequent gene expression. This metabolism-epigenome link sensitizes chromatin methylation to altered SAM abundance, yet the mechanisms that allow organisms to adapt and protect epigenetic

N-Terminal isotope tagging (NIT) is an important proteomic tool for quantifying proteins in complex mixtures. Here we describe a modified version of the isotope-coded propionylation procedure of Zhang et al. [Zhang et al., Rapid Commun. Mass Spectom. 16 (2002) 2325]

Waxy, normal, and high-amylose maize starches were acetylated to various degrees of substitution (DS) in aqueous medium. A stepwise addition of acetic anhydride enhanced reaction efficiency and DS was in the order of high-amylose maize starch (DS 1.72) > waxy maize starch
