Trans fatty acids are unsaturated fatty acids with at least a double bond in trans configuration or geometry.The double-bond angle of the trans fatty acids is smaller than the cis isomeric configuration and the acylchain is more linear, resulting in a more rigid molecule with different physical...

fatty acid- any of a class of aliphatic monocarboxylic acids that form part of a lipid molecule and can be derived from fat by hydrolysis; fatty acids are simple molecules built around a series of carbon atoms linked together in a chain of 12 to 22 carbon atoms ...
Cis fatty acids will cause a kink in the structure of the molecule making it more difficult for the fats to stack upon each other. This explains why most cis fatty acids are found in liquid form. Trans fatty acids do not have the kink in their structure and are, therefore, straight, ...
The trans configuration inherently changes the properties of the fatty acid including the ability of the molecule to 'bend'. The type of fatty acid incorporated into cell structures has the potential to affect multiple cellular functions including cell membrane receptor activity. Source of TFA Humans...
