5. Write the equation of tripeptide Tyr-Lys-Glu acidic hydrolysis (in the presence of hydrochloric acid).
What are the properties of inorganic compounds?
Using Lysine aromatic -amino acid as the example answer the following questions:
1. Draw the Fisher projections of possible stereo isomers and designate their configurations. Which of them takes part in molecules of peptides building?
2. Draw the structure of this -amino acid in isoelectric point (IEP). In what region of pH the IEP is situated?
by slowly bubbling a known volume of gas through it at a known temperature and pressure. In an experiment, 5.00 L of NÃ ¢ gas is passed through 7.2146 g of liquid benzene (C6H6) at 26.0 °C. The liquid remaining after the experi ment weighs 5.1493 g. Assuming that the gas becomes satu rated with benzene vapor and that the total gas volume and temperature remain constant, what is the vapor pressure of the benzene in torr?
A molecule that has three degrees of unsaturation, 8 total carbons, and two halogens.
