Draw Glu-His-Trp-Ser-Gly-Leu-Arg-Pro-Gly peptide. What is the net charge of this peptide at pH 3, 8 and 11? What can you say about pI value of this peptide?

A) Can you please tell me which of these A.A have a negative side chain? Names of choices in picture provided. B) Can you please tell me which A.A have a hydrophobic side chain and why?  Names and choices in picture provided. Thank You so much!!

Torigonal plannes CH - C-N o=), HN CH2 CH-C-OH (a- carbon) CH2 HooC Aspaxagine - Toline - Valine - Arginine - phenylalcmine - Glutamic ocid. 1.Give the name and three letter code for each amino acid in the peptide. e 2. At pH 7, approximately what charge would be on your peptide? Explain your answer. 3. Can your peptide form intra/interchain disulfide bonds? Explain why/why not. e 4. Will your peptide absorb UV and is it fluorescent? Explain why/why not. e 5. What is the probability that your peptide contains a cis peptide bond? Explain your answer.

is it true that aplha and beta are made up of same amino acids but Beta chain is longer than alpha chain？what is other difference and similarity？is the amino aicd sequence exactly the same as well？are their structure the same ？
