Step 1: Introduce about the plasma membrane
Plasma membrane of the cells is the selective barrier and is made up of phospholipid bilayers. The bilayer structure is formed due to the hydrophobic interactions of phospholipid tails. In the plasma membrane proteins, cholesterol and carbohydrates are also present.

- α-Keratin is an intermediate filament with a basic structural unit of two a helices in a coiled coil. Each helix has a seven-residue repeating unit (heptad repeat). A representation of the a helices of a coiled coil dimer is shown. Each letter represents a different amino acid residue. f g d e Review the table of amino acids. a d g f Identify the three true statements about the structure of keratin. ☐ The a helix of the coiled coil is wound less tightly than predicted for an α helix. ☐ Each polypeptide in the dimer has 3.6 residues per turn, and a nonpolar group occurs every 3.5 residues, resulting in a slight winding, or twist, around the other polypeptide, forming a coiled coil. Arg-Ala-His-Glu-His-Thr-Asp is a likely repeat in the a helix of keratin. ☐ Val-Thr-Asp-Ala-Glu-Arg-His is a likely repeat in the a helix of keratin. ☐ The residues at positions b and c are less likely to be polar or charged because they are in contact with the solvent. ☐ Keratin molecules are very strong due…arrow_forwardoligosaccharides are attached to proteins for a variety of reasons. They’re attached to the newly synthesized proteins in the endoplasmic reticulum and golgi apparatus to assign them destination labels, misfolded protein labels, and quality control labels. How does the polarity and charge of these oligosaccharides affect the protein they are bound to?arrow_forwardNon covalent bonds are very important in cell biology, could you explain why and provide an example that illustrates their importance ( do not chose protein folding as an example) What are the different levels of protein structure and what are the different parameters (sequence, type of bonds, etc...) that influence protein folding at these different levels?arrow_forward
