چکیده
Michel Eugène Chevreul entered at 17 the laboratory of Vauquelin, Museum. He began his investigations on animal fats in 1811. They appear as yet most complete and best executed experiments found all chemistry. For first time, he combined fractional solution, crystallization, distillation, melting point determination, ultimate analysis. All started with isolation an acid solid substance, “margaric acid”, a long list fatty acids isolated from various fats. Studying saponification, determined that “anhydrous glycerine” was combining water. After studying human gallstones, discovered “cholesterine” (cholesterol). From whale spermaceti, described “cetin” (mainly cetyl palmitate), containing no glycerol. sheep fat new named “stearic acid”. This component proposed joint patent by Gay-Lussac (1825) for fabrication very efficient candles. several volatile cow goat butter (from C4 to C10). His master work ( Recherches chimiques sur les corps gras d’origine animale, 1823b ) contains experimental procedures theoretical conclusions nature fats, it may be considered treatise lipochemistry.

The biodegradation of the most abundant atmospheric organic C1 to C4 compounds (formate, acetate, lactate, succinate) by five selected representative microbial strains (three Pseudomonas strains, one Sphingomonas strain, and one yeast strain) isolated from cloud water at the puy de Dôme has been studied. Experiments were first conducted under model conditions and consisted of a pure strain incu...

DNA-lipid systems. A physical chemistry study.
It is well known that the interaction of polyelectrolytes with oppositely charged surfactants leads to an associative phase separation; however, the phase behavior of DNA and oppositely charged surfactants is more strongly associative than observed in other systems. A precipitate is formed with very low amounts of surfactant and DNA. DNA compaction is a general phenomenon in the presence of mul...

Introduction A considerable body of knowledge has been accumulated in recent years concerning severe genetic neurological diseases such as Tay-Sachs, Sandhoffs disease, juvenile GM2 gangliosidosis, juvenile GM1 gangliosidosis, chronic Gaucher's disease, and Fabry's disease. Those are in effect genetic sphingolipid-oses (O'Brien et al., 1972). The detection of both homozygotes and heterozygotes ...
