In an alpha-helical protein that spans the cell membrane, __ would likely be in the center of the membrane while __ would likely be associated with the polar head groups and __ would likely be associated with the aqueous environment. (a) Trp, Asn, Ala (b) Leu, Gln, Asp (c) Tyr, Glu, Glu (d) Ile, Arg, Gln I believe the answer to be B or D but I need to explain it. I would think it would be D because the...

1. why might a protein have multiple domains. 2.why a protein might be comprised of more than one chain. 3.why a protein structure might show gaps when the real protein has none. 4.why a protein might bind nucleic acids. 5.why a protein might have disulfide bonds. 6. are ligands important for function or just artifacts of the structure process? 7. Why would the surface of a membrane-bound protein have a different polarity from a soluble one?

The plasma membrane of E. coli is approximately 75% protein and 25% phospholipid by weight. It is known that the average membrane protein molecular weight is 50,000 Da and an average membrane phospholipid molecular weight is 750 Da. Calculate the number of membrane phospholipid molecules present per molecule of membrane protein number of membrane phospholipid molecules: 0.033 molecules Select the additional information that one would need to calculate the fraction of membrane surface covered by phospholipids. the average cross-sectional areas...

QUESTION 9 Sequence analysis of a membrane protein shows four 20 amino acid long stretches of residues that are predominantly hydrophobic Between each of these stretches of hydrodophobic residues, a stretch of predominantly hydrophilic residues is found. From this observation one can reasonably postulate that: A this is a 4 stranded beta barrel which spans the membrane B.this is a glycoprotein o this protein has 4 alpha helical segments that span the membrane o this protein can be removed from...
