racemization造句
1. Aspartic acid has the fastest racemization rate of the stable amino acids and is the acid usually chosen for dating bone samples.
2. The mechanism of the racemization was discussed.
3. Racemization is found with optically active substrates.
4. Racemization is found with optically active substrate substrates.
5. Until his group's new report, scientists hadn't compared racemization and C-14 analyses on the same teeth, Buchholz says.
6. The rate constant of racemization of L-Pro increased with decreasing acidity of the carboxylic acid. However, the racemization of L-His was most rapid in acetic acid.
7. And in these instance, racemization can really come in handy.
8. The rate of racemization of L-His was the most rapid in acetic acid, the suitable catalyst is salicylaldehyde.
9. The dependence of chain scission and racemization on temperature results from molecular motion, "cage effect" and steric hindrance during recombination.
10. By analyzing how much racemization of its aspartic acid occurred, scientists can determine how old the tooth's owner was at death — generally accurate to about 5.5 years, plus or minus 4.2 years.
11. CONCLUSION By the racemization, S-salbuterol can be recycled substantially, increasing the yield of levalbuterol and lowering costs. This method has cheerful prospects for industrialization.
12. By the way, if you're curious about why racemization is so much less accurate a clock than C-14 for dating a tooth's age, part of the explanation has to do with temperature.
