"Trans" fats are unsaturated (with double bonds) triglycerides (fats) where the double bonds are in a trans conformation as opposed to a cis conformation. Only cis conformation is found in nature. In the cis conformation, the two carbon chains on either end of the double bond bend to the same side while in the trans conformation, the two carbon chains bend to opposite sides. Here's a diagram (the horizontal line is the double bond):

Cis double bonds introduce a bend in a fatty acid chain and therefore unsaturated fats with cis double bonds contain bends and occupy more space, leading to lower melting temperature (harder to make solid, usually liquid at room temperatures). The hydrogenation process seeks to make the saturate the double bonds to single bonds by adding hydrogen to the double bonds, making the fatty acids linear and the melting point of the fat higher (solid at room temperature for better storage, e.g. margarine). Trans double bonds are created from cis double bonds as a side-effect of the hydrogenation process, and it so happens that the trans geometry makes the fatty acid chain linear like a single bond. Therefore the hydrogenation process makes the fatty acid chains linear, whether by creating single bonds or trans double bonds, leading to the solidification of normally liquid oils (e.g. vegetable oil).
It turns out that since the trans double bond is not found in nature, the body doesn't know how to handle it. The body senses that trans fats contain double bonds, but when the body puts them to use, their biochemical properties, being opposite to the natural cis fats, cause a variety of health risks, the most significant being cardiovascular diseases.

RafaTrans fatty acids are created through a process called hydrogenation where hydrogen is added to liquid vegetable oils to make them solid at room temperature. They are commonly found in processed foods and are known to raise bad cholesterol levels in the blood, increasing the risk of Heart disease. It is recommended to limit intake of trans fats for better heart health.

What is volatile fatty acid number?
No one fatty acid is volatile.
A type of fatty acid with odd molecular shapes that is created when oils are partly hydrogenated?
Trans fats are created during the partial hydrogenation process of oils, resulting in fatty acids with unusual molecular shapes. These fats are associated with negative health effects and are often found in processed foods. Consuming trans fats should be limited to promote better health outcomes.
Unsaturated fatty acids that have changed to saturated fatty acids are called?
Hydrogenated fatty acids.
Which part of the cell membrane prevent organisms from dissolving in water?
Nonpolar fatty acid chains.Non fatty acid chains
Is hydrochloric acid a fatty acid?
No, hydrochloric acid is not a fatty acid. It is a strong mineral acid composed of hydrogen and chlorine. Fatty acids, on the other hand, are carboxylic acids with long aliphatic tails found in fats and oils.
