Balance of pH of chicks from eggs injected with ascorbic acid and subjected to thermal stress
(2012-12-01)
This study aimed to verify that chicks from eggs injected with ascorbic acid and subjected to heat stress would have changes in acid-base balance, compared to chicks incubated at thermoneutral without injection of ascorbic ...
Organic Acids without a Carboxylic Acid Functional Group
(Journal of Chemical Education 77(7):910-915. July 2000, 2000-07)
This paper presents several organic molecules that have been labeled as acids but do not contain a carboxylic acid functional group. The rationale for the nomenclature and appropriate explanations for the apparent acidity ...

Light emission from tryptophan oxidation by hypobromous acid
(2012-10-08)
The emission of ultraweak light from cells is a phenomenon associated with the oxidation of biomolecules by reactive oxygen species. The indole moiety present in tryptophan, serotonin and melatonin is frequently associated ...

Storage lipids and proteins of Euterpe edulis seeds
(Sociedad Latinoamericana de Microscopía Electrónica y Centro Regional de Investigaciones Científicas y Tecnológicas (Mendoza, Argentina), 2009)
Comparative studies on fatty acid and protein composition of the endosperm and embryo of palmito (Euterpe edulis Martius) were conducted using gas-liquid chromatography and sodium dodecyl sulfate– polyacrylamide gel ...
Diterpenoids from Azorella compacta
(1997)
In addition to mulinolic acid, a new diterpenoid, mulin-11,13-dien-20- oic acid, has been isolated from the aerial parts of Azorella compacta. Its structure was based on a spectroscopic comparison with mulinolic acid and ...
