Studies on the crystalline lens. IX. Quantitative analysis of free amino acids and related compounds.
The concentration of all free amino acids and many related compounds in the lens of rabbits has been determined by ion exchange chromatography, and the concentration of the amino acids in the lens has been compared with those found in a previous study in aqueous and. vitreous humors. The concentration of every free amino acid in the lens was shoiun to be higher than in the aqueous of the poster...
متن کاملBoronic acid catalyzed ene carbocyclization of acetylenic dicarbonyl compounds.
The discovery and development of an efficient ene carbocyclization of 1,3-dicarbonyl compounds bearing pendent terminal alkyne substituents under 3-nitrobenzeneboronic acid catalysis is described. The reaction is efficient, easy to perform and general to a wide range of ketoester substrates.
متن کاملNew acetylenic norlignan compounds from rhizomes of Curculigo crassifolia.
Two pairs of diastereoisomeric acetylenic norlignan compounds with PhCH(OR(1))CH(OR(2))CH(2)C triple bond CPh skeleta: (1R, 2R)-1-O-methylnyasicoside (1) and (1S, 2R)-1-O-methylnyasicoside (2), and (1R, 2R)-crassifogenin D (3) and (1S, 2R)- crassifogenin D (4), were isolated from the ethanolic extract of rhizomes of Curculigo crassifolia. Compounds 3 and 4 are new and their structures were eluc...
متن کاملStudies on the Sensitization of Animals with Simple Chemical Compounds Ix. Skin Sensitization Induced by Injection of Conjugates
In experimental work on sensitization with a group of simple chemical substances, strong evidence was obtained for the view that the production of hypersensitivity depended upon the formation of antigenic combinations in the body (1). As a corollary, the direct administration of in vitro conjugates in these cases should lead to skin sensitivity towards the corresponding low molecular substance....
متن کاملTime-resolved fluorescence studies on protoporphyrin IX-apohorseradish peroxidase.
The hemin moiety of horseradish peroxidase (donor:hydrogen-peroxide oxidoreductase, EC 1.11.1.7) was removed and the apoprotein reconstituted with the fluorescent protoporphyrin IX. Steady-state and time-resolved fluorescence properties of the HRP(desFe) adduct were examined; the multifrequency phase and modulation method was utilized for lifetime and dynamic polarization studies. The emission ...
