Question

3) Fill in the blanks, with one of these 5 amino acids (1 point for each correct answer. Each amino acid will be used once for an answer) Lysine Cysteine ValineTryptophan Aspartate a) If you dissolvein water, the resulting pH would be about 8.5 b) if you dissolve c) in water, the resulting pH would be about 4 residues would most likely be buried in the core of a folded protein structure d) Collagen does not absorb strongly at 280 nm. This is because its sequence does not contain many residues. d) can form disulfide bridges in proteins

Explanation / Answer

a.

If you dissolve lysine, the pH of water would be 8.5

b.

If you dissolve aspartate, the pH of water would be 4

c.

valine residues will be most likely buried inside the core of protein

d.

Collagen does not absorb much at 280nm, this is because it does not contain many tryptophan residues

e.

Cysteine can form disulfide bridges in proteins.
