What is the name of the process that converts unsaturated fats to saturated fats?
Hydrogenation is a chemical process that adds hydrogen to the unsaturated bonds on the FA chains attached to the TAG backbone. In this way, an unsaturated fat can be turned into a saturated fat and increase its melting point (List and King, 2006).
How do fatty acids become saturated?
Fatty acids may be saturated or unsaturated. In a fatty acid chain, if there are only single bonds between neighboring carbons in the hydrocarbon chain, the fatty acid is said to be saturated. Saturated fatty acids are saturated with hydrogen since single bonds increase the number of hydrogens on each carbon.
What is the process of hydrogenation?
Hydrogenation involves the chemical addition of hydrogen to the unsatu- rated carbon – to – carbon double bonds in a fatty-oil or fatty-acid molecule. The reaction is carried out by mixing the heated oil and hydrogen gas in the pres- ence of a catalyst.
What do fatty acids convert to?
Fatty acids are oxidized through fatty acid or β-oxidation into two-carbon acetyl CoA molecules, which can then enter the Krebs cycle to generate ATP. If excess acetyl CoA is created and overloads the capacity of the Krebs cycle, the acetyl CoA can be used to synthesize ketone bodies.
How do you convert saturated to unsaturated?
Answer: It is possible to convert unsaturated hydrocarbons to saturated hydrocarbons by an addition reaction in which hydrogen is added to unsaturated hydrocarbon in the presence of a catalyst such as nickel which breaks the double or triple bond to form saturated hydrocarbon.
What is meant by saturated and unsaturated fatty acids?
Saturated fatty acids lack double bonds between the individual carbon atoms, while in unsaturated fatty acids there is at least one double bond in the fatty acid chain. Saturated fats tend to be solid at room temperature and from animal sources, while unsaturated fats are usually liquid and from plant sources.
What is the initiation step of hydrogenation?
Step 1: A hydrogen molecule comes in and reacts with the metal atom on the surface of a catalyst (a). As a result, the hydrogen molecule breaks its bonds so that each individual hydrogen atom can form a bond with the metal atom on the surface of the catalyst (b).
How is oil converted into fat?
Either a hydrogen molecule can react with the carbon atoms in an unsaturated bond to convert it into a saturated single bond. This has a higher melting point and so a liquid oil can be converted into a solid fat. The other way it can react is to convert the cis double bond into a trans double bonds.
What causes an unsaturated fatty acid to have?
Unsaturated fatty acids have at least one double bond between carbon atoms. This causes them to have one less hydrogen atom and allows for bending of the overall molecule.
What type of bond does an unsaturated fatty acid contain that a saturated fatty acid does not?
double bonds
Saturated fatty acids do not contain any double bonds or other functional groups along the chain. Unsaturated fatty acids contain at least one pair of carbon atoms linked by a double bond enabling the addition of other atoms to these carbons.
How are unsaturated fatty acids converted to saturated fatty acids?
Unsaturated fatty acids may be converted to saturated fatty acids by the relatively simple hydrogenation reaction. Recall that the addition of hydrogen to an alkene (unsaturated) results in an alkane (saturated). A simple hydrogenation reaction is: H 2C=CH 2 + H 2 —> CH 3CH 3.
What happens to trans fat in partial hydrogenation?
Trans Fat: When naturally occurring unsaturated fatty acids are altered by partial hydrogenation, they are converted to saturated fatty acids, which have the effect of straightening the chains and changing the physical properties.
What is the new name for saturated fatty acid?
Write the hydrogenation reaction for linoleic acid to hydrogenate all of the double bonds. What is the new name for this fatty acid? Hint: count carbons. Answer linoleic has 18 carbons, the saturated fatty acid is stearic acid.
Which is better trans fat or saturated fat?
Trans fat has both the benefits and drawbacks of a saturated fat. On the plus side, it has a longer shelf life than regular vegetable fat and is solid at room temperature.
