0 used to describe an isomer (= one of a group of similar chemical substances) in which the atoms are arranged on the same side of the molecule, especially on the same side of the carbon chain (= a line of connected carbon atoms):
The traditional cold-pressing method of extracting vegetable oils preserves the cis fatty acids in their natural form.
The polyacetylene chain can adopt two different shapes, called cis and trans, where the trans configuration is the most chemically stable.
1 used to describe someone who feels that they are the same gender (= sex) as the physical body they were born with:
2 used to form the names of chemical substances in which the atoms are arranged on the same side of the molecule, especially on the same side of the carbon chain (= line of connected carbon atoms):
In 1969 researchers discovered that only the cis-DDP isomer killed tumours.
Some of our samples show an increased ratio of the 16-and 18-carbon trans vaccenic acid to the cis isomer.
Chemists initially make polyacetylene in the cis form, and convert this to the trans by heating it to 200°C in helium.
Some of the double bonds that remain then change type, from cis to trans, and these have been found to be particularly damaging to our health (otherwise called "hydrogenated fat").
As a cis man, it's hard for me to understand what trans people go through.
He dressed flamboyantly, but he was still a cis male.
A cis female is a naturally-born woman or girl whose psychological gender identity is also female.
Cis people do not necessarily conform to gender-stereotyped behaviours, appearances or roles.
In the absence of sufficient cis-omega 3 fatty acids in our diet, these fatty acid substitutions take place.
