Lipid content was determined gravimetrically after extraction with petroleum ether. Ash weight was measured after combusting samples at 550°C. Protein content was calculated as the difference between ...

These aromatic extracts are produced as by-products during the refining of crude oil. These DAEs can be blended to make other petroleum substances. Due to their untreated nature, these substances have ...

However, it has not been clear yet how exactly this protein interacts with its ligands and whether its structure changes depending on the type of molecule being transported. However, it is known ...

A short and efficient synthesis of heptadeuterated 2,2,4,4,5,7,7-d7-cholestane (1) from cholesterol (3) is described. The deuterated material will be useful for the analysis of different sources of ...
