WebThis is due to the fact that during the condensation of the triacylglycerol, two fatty acids join to form double bonds. When the fatty acids are attached to the glycerol backbone, they will fit together more closely when they are in the cis configuration. This contributes to the triacylglycerol's increased stability.
