Question

If you extracted a 21-residue amphipathic helix from a protein and placed it in a buffer solution at pH7_(_()) what do you think would happen? A. The peptides would form the amphipathic helix seen in the protein structure and associate with other helices because of the hydrophobic effect B. The peptides would precipitate C. The helix would form since water hydrogen bonding would satisfy main chain hydrogen bonding D. The helix would not form since water hydrogen bonding would satisfy side chain hydrogen bonding If you extracted a 21-residue amphipathic helix from a protein and placed it in a buffer solution at pH Z what do you think would happen? A. The peptides would form the amphipathic helix seen in the protein structure and associate with other helices because of the hydrophobic effect B. The peptides would precipitate C. The helix would form since water hydrogen bonding would satisfy main chain hydrogen bonding D. The helix would not form since water hydrogen bonding would satisfy side chain hydrogen bonding

You have designed a polypeptide (a small protein) with 20 amino acids that you predict will be stable as a single transmembrane alpha helix in a biological membrane. Which of the following are true? Select one or more: a. This protein does not form intramolecular or intermolecular hydrogen bonds. b. Both the N-terminus and the C-terminus of this protein are charged at neutral pH. c. All of the protein's side chains radiate outward from the core of the alpha helix and may contact the hydrophobic interior of the membrane. d. All or most of the amino acids are nonpolar.

11. Which of the following residues would most likely be buried in the interior of a water soluble, globular protein? a. Asp b. Ser c. Lys d. Phe e. Gln 12. In the ̑-helix, the hydrogen bonds: a. are roughly parallel to the axis of the helix b. are roughly perpendicular to the axis of the helix c. occur mainly between electronegative atoms of the R groups d. occur mainly between some of the amino acid residues of the helix e. occur near the amino and carboxyl termini of the helix 13. Which of the following statements does not apply to collagen? a. It contains hydroxylated amino acids. b. The polypeptide forms a left-handed helix. c. Hydrogen bonds between the —OH groups of 4-hydroxyproline residues stabilize the helix. d. There is an absolute requirement for Gly every third position. e. The triple helical structure twists in the right-handed direction. 14. A D-amino acid residue would interrupt an ̑-helix made of L-amino acid residues. Another naturally occurring hindrance to the formation of an ̑-helix is the presence of: a. a negatively charged Arg residue. b. a nonpolar residue near the carboxyl terminus. c. a positively charged Lys residue. d. a Pro residue. e. two Ala residues next to each other.

Sort the following secondary structure characteristics into the correct categories. Items (6 items) Categories α helix only Cylindrical structure One full turn every 3.6 amino acids β sheet only Consists of antiparallel or parallel strands Side chains alternating above and below the structure Both α helix & β sheet Can be formed by many sequences Formed by hydrogen-bonding between backbone atoms Predict what would happen to the secondary structure of a protein if an alcohol that disrupts hydrogen-bonding were added. Choose one or more: A. The β sheets would unfold, disrupting protein structure. B. Individual amino acids would be hydrolyzed from the protein, disrupting protein structure. C. Nothing would happen to the protein; hydrogen-bonding is not important for secondary structure. D. The α helices would unfold, disrupting protein structure.

00:01 Here we have been given that a polypeptide which is having around 20 amino acid.
00:12 It was designed and we had predicted that it will be stable as a single trans membrane helix in a biological membrane.
00:36 And we have to find out that among the given statements which of them are true regarding it.
00:41 So here our correct option will be option d.
00:45 That is all of the amino acid or most of them are non -polar.
00:50 This is because if we talk about non -polar amino acids, then they are basically those amino acids which have no polarity and they are charged either positive or negative amino acids.
01:12 And this is why they are basically used in the preparation of single trans membrane because for the.
01:18 Stability of membrane we require the charges on either of the side so as to make a stable situation a stable structure with each of the molecules standing on their own position and this can only happen if there is charge present on it which will attract from both of the sides now our second question it is asking that initial folding was done of a protein which is in actual exorgenic along with it it is spontaneous and we have to find out the condition of free energy enthalpy as well as entropy for these conditions so first of all if we talk about free energy then they will be spontaneous and will act according to the direction of folding.
02:51 Next if we talk about the enthalpy and entropy then it states that as the protein folding then at that point of time are enthalpy denoted by...
