1 Answer

Answer :

(4) high proportion of unsaturated fatty acids. Explanation: The membranes of chill sensitive plants have been found to have about a 2:1 ratio of unsaturated to saturated fatty acids. It has been seen that the proportion of unsaturated membrane fatty acids increases and the critical temperature decreases when chill-sensitive plants are acclimated to a low temperature.

Drying oils contain a fairly large proportion of – (1) fats (2) proteins (3) saturated fatty acids (4) unsaturated fatty acids

Description : Drying oils contain a fairly large proportion of – (1) fats (2) proteins (3) saturated fatty acids (4) unsaturated fatty acids

Last Answer : (4) unsaturated fatty acids Explanation: They contain a high percentage of "polyunsaturates" (polyunsaturated fatty acids). Most drying oils owe their drying properties to the presence of a large percentage of linolenic acid (which derives its name from "linseed"), which is highly unsaturated.
