Given is the representation of a transmembrane protein. Calculate the thickness of the membrane if only alpha helixes are embedded in it. One turn = 5.4Å
Please read: The reason I didn't submit my attempt is that, I thought because there isn't an exact and precise depiction of the protien molecule and also the question is vague so I hesitated. I counted the number of turns ie 7 but still there was a lingering doubt "what if I am wrong, I would make a fool of myself."
What I know:
- Protiens basically bunch of amino acids bound by polypeptide bond.
- Primary structure is the sequence of the amino acids.
- The secondary structure us due to the Hydrogen Bonding between the Oxygen atoms having partial -ve charge and Hydrogen atom attached to the Nitrogen, within the backbone only. eg: alpha-helixes, beta-sheets, Turns, Loops
- Tertiary Structure is due to the interaction between the different R groups in the amino acids. Like the disulphide bonds, hydrophobic interactions, H-bonds, Vanderwaal forces.
- Quaternary Structure is due to the overall 3D structure which is result of the aggregation of the polypeptide subunits.
Please go easy on me, its my first time posting here and I am still a 1st year in college and 2nd Sem is gonna start next week.
