Solved in 2 steps
- Give at least 10 functions of protein and describe each function. Cite an example for each function if there are any.Select ALL statements that are true about the isoelectric point (pI) of a protein a.Protein carries a net negative charge at its pIb.There is no net charge on the protein at its pIc.Above its pI, a protein is negatively chargedd.pI depends on the amino and carboxylic acid content of a proteinUnderstanding the Relevance of Chaperones in Protein Folding Protein molecules, like all molecules, can be characterized in terms of general properties such as size, shape, charge, solubility/hydrophobicity. Consider the influence of each of these general features on the likelihood of whether folding of a particular protein will require chaperone assistance or not. Be specific regarding just Hsp7O chaperones or Hsp7O chaperones and Hsp60 chaperonins.
- identify the interaction that may be produced between the side chain of amino acid residues found at the N-terminus and the C-terminus of the peptide. List all possible peptides that can be formed from the given peptide (use three character/letter abbreviations for each amino acid, i.e., Ala-Gly-Val). NOTE: Any excess will be deducted to the correct answers. Be careful in evaluating your answers.Protein Concept Map Add these terms to your concept map should include these concepts and details: Structure (functional groups, shape); Monomer; Linkage; Properties; Functions; Key terms from the Partial List of Key Terms from the Minds Partial List of Key Terms essential amino acid amino acid side group/R-group peptide bond polypeptide receptor neurotransmitter hormone secondary structure tertiary structure quaternary structure fair test hydrophobic hydrophilic intermolecular force of attractionNeed help The β chains of HbA and HbS were treated with trypsin, and the sequence of the N-terminal tryptic peptides are as given below. Do these peptides separate from each other in an electric field if the pH is 7.0? Explain in detail the reasoning behind your answer and include your calculations for the charge of each peptide in your answer. HbA: Val-His-Leu-Thr-Pro-Glu-Glu-Lys HbS: Val-His-Leu-Thr

Along with it also mention that toward swhichelectrode (cathode or anode) will the peptide move? Please remember that cathode is a negativeelectrode and anode is a positive electrode. Ile-Lys-Arg-Trp-Lys-Asn-Glu-His-Pro-Asp-Ala-Tyr-Phe-Glu-Met-Phe-Gly-ValThe mobility of integral proteins can be measured by physical state of the ______________a) amino acidsb) external phospholipidsc) membrane phospholipidsd) membrane appendagesDescribe how a polypeptide can fold to become a functioning protein. Be sure to address the four levels of protein (folding or organization known as hierarchy of structure). In addition, describe three different jobs proteins can perform if the protein has the correct shape.
- had a response from a peer and this is what they said: You mentioned that aliphatic amino acids play a role in protein folding and stability by forming together in the protein's hydrophobic core. Could you elaborate on how this process works and provide more details on the structural aspects involved in this interaction? I am not too sure how to respond to this. Thank you.Hydropathy plot analysis of your protein of interest reveals a single, prominent hydrophobic peak. However, you later discover that this protein is soluble and not membrane associated.
