Blue metal complex pigments involved in blue flower color
The blue pigment of cornflower, protocyanin, has been investigated for a long time, but its precise structure was not entirely explained until recently. The molecular structure of the pigment was recently shown to be a metal complex of six molecules each of anthocyanin and flavone glycoside, with one ferric iron, one magnesium and two calcium ions by X-ray crystallographic analysis. The studies...
متن کاملEffect of Amaranthus Pigments on Quality Characteristics of Pork Sausages
The objective of this investigation was to evaluate the possibility of substituting Amaranthus pigments for nitrates in the of manufacture pork sausage. Five treatments of pork sausages (5% fat) with two levels of sodium nitrite (0 and 0.015%), or three levels (0.1%, 0.2% and 0.3%) of pigments extracted from red Amaranthus were produced. The addition of Amaranthus pigments resulted in the signi...
متن کاملRare-earth vs. heavy metal pigments and their colors from first principles.
Many inorganic pigments contain heavy metals hazardous to health and environment. Much attention has been devoted to the quest for nontoxic alternatives based on rare-earth elements. However, the computation of colors from first principles is a challenge to electronic structure methods, especially for materials with localized f-orbitals. Here, starting from atomic positions only, we compute the...
متن کاملOrigin of Bile Pigments
S. H. ROBINSON (Boston) described a new experimental technique for studying the early labelled component of bilirubin in the ligated bile duct of the Gunn rat. Using 14C bilirubin he measured the total miscible bilirubin pool. In addition, the rate of bile pigment formation following the administration of 2-14C glycine was estimated. This allowed precise assessment of bilirubin and haem product...
