The decomposition of cystine by alkaline reagents has received much study, particularly in recent years by Gortner and his collaborators (1) and by Andrews (2). Consideration of the results obtained by these workers leads to the conclusion that the process is far from simple, apparently consisting of a series of successive reactions, possibly accompanied by simultaneous side reactions. The expe...

Torsional and rotational spectroscopic properties of pyruvic acid are determined using highly correlated ab initio methods combining two different theoretical approaches: Second order perturbation theory a variational procedure in three-dimensions. Four equilibrium geometries acid, Tc, Tt, Ct, CC, outcome from search with CCSD(T)-F12. All them can be classified the Cs point group. The calculati...

Mineral profile and some selected components of three cultivars of onion (Allium cepa L.) (Dan Zaria, red creole and white creole) bulb were compared with garlic (Allium sativum L.) clove. This was pertinent to establish their potentials in ensuring adequate nutrition and food security. Simultaneous multi-element analysis was done by inductively coupled plasma-optical emission spectroscopy (ICP...

this research evaluated the effects of onion curing methods on the qualitative traits of iranian onion cultivars (azarshahr red, neishabour red, kashan white, qom white). testing was carried out in the autumn and winter of 2007. the experimental design was factorial with two factors and three replicates. the factors were traditional and sunlight curing methods at 42°c for 12 hr for 48°c for 4 h...

Anthocyanins are responsible for the color of grapes and wine, an important attribute of their quality. Many authors have used anthocyanins profile to classify the grape cultivars and wine authenticity. The anthocyanin profiles of grape berries of Vitis amurensis, its hybrids and their wines were analyzed by HPLC-ESI-MS/MS. The results identified 17 anthocyanins in these grape cultivars, includ...
