4. Consider the following amino acids. Based off their side chains, which would you suspect to be the most prevalent in the hydrophobic core of a protein. Justify your response. 5. Are the hydrophobic interactions caused by the repulsion between water and nonpolar molecules? Explain in your own words what happens to the water structure near hydrophobic molecule? Is water special?
Consider a protein with the acidic side chains, Amino Acid side-chain Arginine pKa = 12.48 Aspartic Acid PKa = 3.90 Cysteine pKa = 8.33 Glutamic acid pKa = 4.07 Histidine pKa = 6.04 Lysine pKa =10.79 Tyrosine pKa =10.13 Given that the pH of blood is about 7.3, how many of the above side chains would be mostly in their ionic form (A-) in blood? 2 3 4 5

Considering the side chain of each of the amino acids at pH 7.4, is that amino acid classified at neutral, basic, or acidic? Neutral Basic Acidic Answer Bank Leu histidine Thr H3C-c-coo TOOC-CH2-c-COO NH3 NH3 glutamate H2N-C-CH2-C-Coo NH3
)The enzyme Rubisco contains a reaction center that involves the
side chains of four key amino acids, Lys201, Asp223, Glu246,
His294. These occur in that order in the primary sequence, but they
are not directly connected.
Use the outline to draw in the correct structures for each of
the amino acids (do not need to include peptide bonds). Use the
correct ionized state for each of them at pH 7. (pKa values for
side chains of Lys, Asp, Glu, His...
It is not amino acids side chain
The cholesterol molecules associated with the B2-adrenergic receptor orient so that their lone hydroxyl is near the inner leaflet edge. This is the only atom in cholesterol with hydrogen-bonding potential. Given the consistency of this orientation, identify the hydrogen bonding partner that best explains this. Amino acids side chains of the B-2 adrenergic receptor Alcohol portion of the phosphoglyceride. Phosphate group of the phosphoglyceride. Glycerol of the phosphoglyceride. • Fatty acid acyl carbonyl...
