Practice question
Question
Circular dichroic spectra of some proteins show a strong negative ellipticity band at 200 nm. Which of the following secondary structures is characterized by the presence of this band?
Explanation
The principle of enzyme catalysis and lipid structure explains that substrate affinity, transition state stabilization and phospholipid composition govern function. Hence intrinsically disordered structure fits best because it reflects catalytic efficiency and membrane organization, as documented in authoritative sources on biochemistry.
