The trans form is the more favoured state because in this arrangement repulsion between non-bonded atoms connected to the Cα centre are minimized. 

For most peptide bonds the ratio of cis to trans configurations is approximately 1:1000.

#Unit 1. Molecules and their Interaction Relevant to Biology

The amino group at C-2 bears a fatty acid in amide linkage.

The fatty acid is usually saturated or monounsaturated, with 16, 18, 22, or 24 carbon atoms.

Ceramide is the parent compound for this group.

#Unit 6. System Physiology – Plant

In CAM plants, formation of the C4 acids is both temporally and spatially separated. At night, CO2 is captured by PEP carboxylase in the cytosol, and the malate that forms from the oxaloacetate product is stored in the vacuole
