Question
Chapter 21, Problem 21.88P
Interpretation Introduction
Interpretation:
The reason for the cell membranes of bacteria grown at 200 C having higher proportion of unsaturated fatty acids as compared to the bacteria of same species grown at 300 C should be explained.
Concept introduction:
Polyunsaturated fatty acids in short PUFAs are the fatty acids which have more than one double bonds within the backbone. It incorporates several vital compounds like important fatty acids.
