The fatty acids elaidic acid and oleic acid have exactly the same structural formulae, with one double bond in the chain. However, the shapes of the chains are different, as shown in the diagram.
Which row shows the effect of the presence of these fatty acids on the structure and behaviour of a cell surface membrane?
1 )
(elaidic acid) does not fit closely with other fatty acids so that the membrane is less fluid at high temperatures
(oleic acid) fits closely with other fatty acids so that the membrane is less fluid at low temperatures
2 )
(elaidic acid) does not fit closely with other fatty acids so that the membrane is more fluid at low temperatures
(oleic acid) fits closely with other fatty acids so that the membrane is less fluid at low temperatures
(elaidic acid) fits closely with other fatty acids so that the membrane isless fluid at high temperatures
(oleic acid) does not fit closely with other fatty acids so that the membrane is more fluid at low temperatures
4 )
(elaidic acid) fits closely with other fatty acids so that the membrane is more fluid at low temperatures
(oleic acid) does not fit closely with other fatty acids so that the membrane is more fluid at high temperatures
