Lipids — Overview & Importance in Biology

When a double bond forms, it can take 2 different confirmations--either cis or trans. As shown in the figure above, if it is the cis confirmation, it will form a kink, while the trans variant will. Lipids are able to take the trans confirmation (called trans fats), and can have serious health complications. In what way would a cis-unsaturated fat differ from a trans-unsaturated fat?
