How does hydrogenation of polyunsaturated fats make them more solid-like?

Organic molecules consist mainly of carbon, hydrogen, and (often) oxygen atoms. Saturated fats refer to those fats whose molecules contain all the hydrogen atoms they can. Unsaturated fats contain some double bonds between some of the carbons instead. Hydrogenation breaks the double bonds, making two single bonds for each carbon; one of those will stay between the carbons, and the others will attach to hydrogen atoms supplied from some other substance. A very simple example would be ethane: H3C-CH3, which is saturated, and ethene: H2C=CH2, which is unsaturated. By breaking one of the two carbon-carbon bonds and substituting hydrogen atoms, the ethene will convert to ethane.

Hydrogenation is the process of adding hydrogen molecules to a fat; saturating the fat molecule with hydrogen. Therefore hydrogenation essentially takes an unsaturated fat and transforms it into a saturated fat. This is why these types of unnatural saturated fats are known as trans-fats.
So, once you consider this fact, your question then becomes: is an unnatural saturated fat healthier than a natural saturated fat? Quite obviously naturally occurring saturated fats are going to be healthier than non-naturally occurring saturated fats because our bodies are able to process them.

Definition of a hydrogenated fat?
Hydrogenation is a process of adding hydrogen molecules to unsaturated fats which makes plant oils that are liquid at room temperature, solidify. These fats are also called trans fats. The hardening of the fat extends its shelf life so that the oil can by used over and over again. While hydrogenation does not make the fat completely saturated, it creates trans-fatty acids, which act like saturated fats. These fats raise cholesterol.
What are trans fats?
Trans fats are a produce to "hydrogenation" of oils. Long ago, someone discovered that cooking oils can be modified to keep it from turning "rancid", and can make it turn to the consistency of butter when hydrogen is forced into the oil under pressure. The process is called hydrogenation. Some of the oil molecules do not complete the process and end up being called "trans fats". These types of fats are said to be responsible for corinary disease and have been blamed for other medical conditions as well. The human body has never been able to adequately establish a way to deal with trans fats
How much fats should you have in your diets?
The USDA guidelines recommend two to three teaspoons of these high-calorie but oh-so-tasty flavorings per day. make sure you eat the good fats (Monounsaturated fat and polyunsaturated fats) that help lower your LDL cholesterol. stya away from saturated fats that raise cholesterol levels.
What percentage of fat should be consumed a day?
In general, no more than 30% of your calories should be from fat each day. We like to say about 10% from polyunsaturated fats, 10% from monounsaturated fats, and 10% or less from saturated fats. You can find polyunsaturated fats in a lot of vegetable oils and nuts. You can find monounsaturated fats in olives and avocados. You need fat for your body to function, just make sure you are getting it from the right sources!
Where is margerine from?
Margarine is made from vegetable or animal fats or oils that have undergone a chemical transformation known as hydrogenation to make them solid at room temperature and then mixed with milk and other ingredients to make them taste OK. Margarine was developed by the French chemist Hippolyte Mège-Mouriès in the late 1860s. The hydrogenation process makes some solid fats that are not known in natural plants and animals (called trans fats see the link below). Some nutritional experts advise that we should avoid these in our diet. In response some margarines are now solidified by an emulsification process which avoids this chemical transformation step.
What is the definition of Saturated fat?
With organic compounds, you can have carbon atoms bonded together with single bonds, double bonds, and triple bonds. If all of the carbon bonds in a fat are single bonds, the fat is saturated. If one of the bonds is a double bond, it is mono-unsaturated. If more than one bond is unsaturated, it is polyunsaturated. Sometimes industries add hydrogen to a double bond and make it hydrogenated. They can add it in one of two ways. They can make it a trans fat or they can make it a cis fat. Nature also hydrogenates fats. Nature makes cis fats. Your body has no problem with cis fats. Nature does not make trans fats. Your body has problems with trans fats. Industries can produce cis fats but find it easier to produce trans fats. Making trans fats illegal will force them to make cis fats.
Does soy margarine have trans fat?
Yes, lots, because of the high amount of unsaturated bounds there is a big chance for incomplete hydrogenation in the fat hardening process, which is needed to turn vegetable oil into solid fats. The solid fats make oil into margarine. Incomplete hydrogenation means that double bounds in CIS position, are transformed into TRANS bounds, because TRANS bounds have lower energetic levels are more stable. When there is sufficient Hydrogen the double bounds disappear and you get saturated fats. We humans have no specific metabolic enzymes to consume trans fats. They stick everywhere and are solid also in the body. They can only be cleaned up in the human body with the antitoxin metabolism.
What fat is the most unhealthy monounsaturated saturated polyunsaturated?
The polyunsaturated fats are considered now as healthful.
Is vegetable oil high in polyunsaturated fats?
The lipid composition of plant-derived oils differ depending on the source. Some plant oils contain more saturated fat than unsaturated. These include palm oil, palm kernel oil and coconut oil. Other oils, such as sunflower and soybean oil contain mainly polyunsaturated fat and canola and olive oil is rich in mono-unsaturated oil. Margarine is produced by partially hydrogenating the unsaturated fats, to make them more solid, so part of the health benefit of these oils is then lost.
