Question

Given the melting profile of a membrane bilayer consisting of

(see attached diagrams)
where R = palmitate (16:0),

(see graph)

where the x-axis is temperature in °C and
the y-axis is the degree of fluidity (higher
value means the membrane is more
fluid), in what direction does the curve
shift if:
a. the palmitate were replaced with oleate (18:1)
b. the palmitate were replaced with stearate (18:0)
c. the choline head group is replaced with –OCH2 CH3
