of the physiologically tolerable acid addition salts or N-oxides. Furthermore, the invention also includes antitumor agents comprising as active compound one or more N-substituted indole-3-glyoxylamides according to the general formula 1 and, if appropriate, their physiologically tolerable acid ...
(+)- and (-)- tartaric acid Enantiomeric excess (ee for shorthand) is a way to calculate how much more of one enantiomer is in a solution, and the enantiomeric excess formula is as follows: {eq}ee\% = 100*\frac{ [R] - [L] }{ [R] + [L] } {/eq} Where R and L are...
A peptide bond is between a) the amino group of one amino acid with the oxygen of the next amino acid. b) Nitrogen of one amino acid with the amino group of the next amino acid. c) the acid portion of one amino...
Unlike enantiomers, diastereoisomers need not have closely similar physical and chemical properties; they may differ as greatly as do structural isomers. For example, either of the optically active tartaric acids melts at 187° C (369° F), whereas mesotartaric acid melts at 143 °C (290 °F...
Its chemical formula is C-9, H-8, O-4. Acetylsalicylic acid is an example of an organic compound, which means it contains carbon. Is cooking oil organic or inorganic? Vegetable oil is an organic compound obtained from seeds or other plant parts, consists of lipids, such as fatty acids ...
The suitable harvesting period for Dendrobium is from November to April of the following year, and the dry matter content (DMC), yield, and accumulation of effective chemical components change with different growth times. Usually, in the harvesting of Dendrobium, the period with higher yield can ...
