Get started for freeUse the given experimental data to deduce the sequence of an octapeptide that contains the following amino acids: Ala, Gly (2 equiv), His (2 equiv), Ile, Leu and Phe. Edman degradation cleaves Gly from the octapeptide, and carboxypeptidase forms Leu and a heptapeptide. Partial hydrolysis forms the following fragments: Ile-His-Leu, Gly, Gly-Ala-Phe-His, and Phe-His-Ile.
What amino acid is formed when CH3CONHCH(CO2Et)2is treated with the following series of reagents:
Consider two molecules of a tetrapeptide composed of only alanine residues. Draw the hydrogen bonding interactions that result when these two peptides adopt a parallel β-pleated sheet arrangement. Answer this same question for the antiparallel β-pleated sheet arrangement.
L-thyroxine, a thyroid hormone and oral medication used to treat thyroid hormone deficiency, is an amino acid that does not exist in proteins. Draw the zwitterionic form of L-thyroxine.
Explain why the pKaof the -NH3+group of an -amino acid is lower than the pKaof the ammonium ion derived from a amine . For example, pKaof the group of alanine is 9.87 but the pKaof is 10.63.
