(T/F) A biochemical reaction, without a catalyst or thermodynamic coupling, takes 50 years to reach a state of equilibrium. Without more information, we cannot make a determination on either the value of the Keq constant or the positive or negative value of the ΔG of the reaction. Correct Answer-False (T/F) Due to its small size, the amino acid glycine can be found in tight turns in a protein structure. Correct Answer-True (T/F) The ΔG of a reaction is defined as the energy required to b...

how are H bonds formed in beta sheets? Correct Answer-- between strands - H-bonds are lateral why do proteins fold if it would lower entropy? Correct Answer-- the hydrophobic effect - deltaH --> all of the interactions happening w/in the protein are favorable + overcome the unfavorable entropy of folding what types of interactions stabilize 3* structures? Correct Answer-- H-bonds - ion pair / salt bridges - van der Waals interactions: weak electrostatic interactions b/t induced dipo...
