 1. Inhibiting OPG production

2. Stimulating RANKL formation

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.
