What is the Difference Between Cis and Trans Fatty Acids?

🆚 Go to Comparative Table 🆚

The main difference between cis and trans fatty acids lies in the geometric arrangement of the hydrogen atoms and their impact on health. Here are the key differences:

  1. Geometric arrangement: Cis fatty acids have both hydrogen atoms located on the same side of the double bond between two carbon atoms. In contrast, trans fatty acids have the two hydrogen atoms on opposite sides of the double bond.
  2. Occurrence in nature: Cis fatty acids are typical in natural foods, while trans fatty acids

    The main difference between cis and trans fatty acids lies in the arrangement of hydrogen atoms in the molecule and their health effects. Here is a comparison table of cis and trans fatty acids:

    Property Cis Fatty Acids Trans Fatty Acids
    Health Effect Generally good for health unless consumed in unreasonably high quantities. Detrimental — lowers good cholesterol and increases the level of bad cholesterol in the body. Harmful to heart health could cause cardiac death.
    Occurrence Naturally occurring in plant-based oils and animal products. While some natural trans fats occur in meat and dairy products, the majority come from processed foods (i.e., hydrogenated oils).
    Atomic Arrangement Hydrogen atoms are on the same side of the double bonds, causing the molecule to bend. Hydrogen atoms are on opposite sides of the double bonds.
    Melting Point Lower melting points, such as 13.4 °C for oleic acid. Higher melting points, such as 45 °C for elaidic acid.

    Cis fatty acids are beneficial and can promote good cholesterol, while trans fats are considered harmful to health. The arrangement of atoms in cis and trans fatty acids affects their physical properties, such as melting points.
