Minor components in pyrrhotite

Analysis of minor components in olive oil.

Virgin olive oil is well known for its high content of phenolic substances that are thought to have health-promoting properties. These substances also contribute to the distinctive taste of the oil. In this study, tyrosol, vanillic acid, luteolin, and apigenin were identified and quantified by liquid chromatography mass spectrometry (LC-MS). In the seven samples analysed, tyrosol, the most abun...

Glycosylated Minor Components of Human Adult Hemoglobin

Human hemolysate contains several minor components designated Hb A,,, Hb Alh, Hb A,,, which are post-translational modifications of the major hemoglobin component A,,. Individuals with diabetes mellitus have elevated levels of Hb A,,, a hemoglobin modified with a glucose moiety at the NH, terminus of each /3 chain. A new chromatographic technique using Bio-Rex 70 is described which not only all...

Phytosterols Are Minor Components of All Vegetable

Supercritical carbon dioxide (SC-CO,). fractionation technique was evaluated as an altemativeprocess for reducing the free-fatty-acid (FFA) content and minimizing the phytosterolloss of rice bran oil (REO) during the process. The effects of pressure (20.5 to 32.0 MPa) and temperature (45 to 80 DC) for isothermal operation of the column on the composition of the resultant fractions were exarnine...

Minor spliceosome components are predominantly localized in the nucleus.

Recently, it has been reported that there is a differential subcellular distribution of components of the minor U12-dependent and major U2-dependent spliceosome, and further that the minor spliceosome functions in the cytoplasm. To study the subcellular localization of the snRNA components of both the major and minor spliceosomes, we performed in situ hybridizations with mouse tissues and human...
