摘要:
The invention includes novel compounds, including but not limited to formula A and formula B, and an improved delivery method. These compounds and methods are useful in preventing or treating diseases or conditions associated with or caused by the presence of free radicals, and are useful for increasing cellular metabolism while simultaneously alleviating the resultant increase in oxidative stress. Specifically, a carnitine is bound to a lipoic acid derivative or to dihydrolipoic acid or its derivatives using a hydrolysable linker to form a single compound.

摘要:
Solid mixed catalysts and methods for use in conversion of triglycerides and free fatty acids to biodiesel are described. A batch or continuous process may be used with the catalysts for transesterification of triglycerides with an alkyl alcohol to produce corresponding mono carboxylic acid esters and glycerol in high yields and purity. Similarly, alkyl and aryl carboxylic acids and free fatty acids are also converted to corresponding alkyl esters. The described catalysts are thermostable, long lasting, and highly active.

A high purity N,N-Carbonyl diimidazole (I) is obtained by the reaction of Imidazole, general formula-II, and bis (trichloromethyl) carbonate. Synthesis of N,N-Carbonyl diimidazole (I) is described:
摘要:
Novel hydroxyphenyl pyruvate dioxygenase (HPPD) polypeptides, variants and fragments thereof, as well as polynucleotides encoding the same, capable of conferring commercial levels of conferring HPPD herbicide resistance or tolerance to plants. Compositions include amino acid sequences, and variants and fragments thereof, for HPPD polypeptides, as well as polynucleotides encoding the same. Methods for the production and use of HPPD herbicide resistant plants that express these novel HPPD polypeptides, methods for selectively controlling weeds in a field at a crop locus, and methods for the assay, characterization, identification and selection of these novel HPPDs are also provided.
