Identify the preferred orientation of amino acid side chains in
the tertiary structure of a protein in an aqueous environment.
A. The hydrophobic side chains will prefer to be on the interior
where they can interact with water molecules in the aqueous
environment.
B. The hydrophilic side chains will prefer to be on the exterior
where they can interact with water molecules in the aqueous
environment.
C. The hydrophilic side chains will prefer to be on the interior
where they...

Question 10 (4 points) Although all protein structures are unique, there are common structural building blocks that are referred to as regular secondary structures, Some proteins have alpha-helices, some have beta-sheets, and still others have a combination of both. What makes it possible for proteins to have these common structural elements? 12 15 a) the hydrophobic-core interactions. b) hydrogen bonds that form along (alpha helices) or between (beta sheets) polypeptide backbones. c) side-chain interactions d) specific amino acid sequences. 7...

39. Albumin is a large protein which circulates freely in human irculates freely in human plasma. Aquaporins act as a channel for water to enter and exit a cell and are located within the lipid bilayer of the cell membrane Based on their physiological locations, how would the tertiary structure of these two proteins mostly likely compare? A. Albumin has a nonpolar core with a polar outer layer, while aquaporins have a polar core with a norpolar outer...

Imagine a transmembrane protein consisting of a single
polypeptide chain. The protein has alpha helices that pass through
the membrane seven times. Between each segment that passes through
the membrane are loops that extend into the cytoplasm or into the
extracellular fluid. The C-terminus of the protein extends into the
cytoplasm and the N-terminus extends into the extracellular fluid.
What is the minimum number of polar
stretches* in the primary structure of this protein?
*polar stretches are contiguous regions of...

14. [6 pts) Indicate which of the following statements is True (T) or False (F) When water interacts with hydrophobic molecules, it becomes more ordered and entropy of the system increases The hydrophobic effect is predominant in protein stability The Ramachandran ploy shows combinations of dihedral angles in a polypeptide chain. A proteins function is directly related to the protein's secondary structure. The B sheet is primarily stabilized by R group interactions Clusters of secondary structures are...

Review| Constants| Periodic Table Protein structure is conceptually divided into four levels, from most basic to higher order Primary structure describes the order of amino acids in the peptide chain. Secondary structure describes the basic three-dimensional structures, a-helices and B sheets. Tertiary structure describes how the secondary structures come together to form an individual globular protein. Quatemary structure results from individual proteins coming together to form multi-subunit protein complexes Part A Complete the following vocabulary exercise relating to the level...
