Is it true lipid molecules that have the maximum number of hydrogen atoms possible are referred to as unsaturated?
No. Lipids with the maximum number of hydrogen atoms are referred to as saturated.
Lipid molecules that have the maximum number of hydrogen atoms possible are referred to as unsaturated?
No. Lipid molecules that are unsaturated have less hydrogen atoms because of carbon-carbon double bonds.
What type of reaction is used to convert oil to a saturated fat?
Oil (vegetable oil usually) is reacted with hydrogen gas in the presence of a catalyst to form saturated fat (normally a solid at room temp)
Is ethane saturated?
As methane belongs to the group alkane compounds which do not contain C=C double bond therefore is saturated and not easily reacting with other molecules.
Why atomic hydrogen is more reactive than hydrogen gas?
Hydrogen gas at standard temperature and pressure exists as diatomic molecules, and much of the chemical potential energy of atomic hydrogen has been evolved as heat along with forming the diatomic molecules.
How do Trans fats resemble saturated fats in that?
Trans fats are man made by adding hydrogen atoms to vegetable oil. This hydrogenation allows the vegetable oil to remain solid at room temperature just like a saturated animal fat.
What uis the difference between saturated fat and unsaturated fat?
Chemically, saturated fats have more hydrogen atoms on the fat molecules.Practically, saturated fats are solid at room temperature (butter, lard, coconut oil) while unsaturated fats are liquid at room temperature (olive and other liquid vegetable oils).
What are unsaturated fats and saturated fats?
You have one or more double bonds between carbon atoms in unsaturated fat molecules. You have no such double bonds in the structure of saturated fat molecules. You have all the single bonds between the carbon atoms.
Which is the gas that is used for converting vegetable oils into saturated fats?
Hydrogen. The process is called hydrogenation.
What is more heathful fat hydrogenated fat unsaturated fat saturated fat or trans fat?
Hydrogenated fats actually are vegetable oil blasted with hydrogen, so these fats are behave like saturated fats. This hydrogen makes the fat harder so it's not at all healthy. Saturated fats haven't any carbon-carbon double bonds, in other words it fully saturated with hydrogen atoms. Hydrogen gas pumped through the mixture at high pressure, and then the excited hydrogen atoms penetrate the vegetable oil molecules and change them into trans-fats. So it is always recommended to consume unsaturated fats instead of other fats.
What type of triglycerides are solid at room temperature?
Saturated fats and trans-fats are solid at room temperature. Polyunsaturated and monounsaturated fats (oils) are liquid at room temperature. Trans-fats are liquid fats that are treated chemically and thermally to mimic saturated fats, usually in a process called hydrogenation. This process in a nutshell (it's a bit more complicated) injects hydrogen into the oils at high temperature and high pressure producing polymers (plastics) from the hydrocarbon molecules in the oils. Most vegetable shortenings are produced this way, shortenings (solid fats) that are not natural saturated fats are trans-fats.
How can you tell if fat is saturated?
Saturated fats have no double bonds in their chemical structure. They are “saturated” with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature.
Is it true lipid molecules that have the maximum number of hydrogen atoms possible are referred to as unsaturated?
No. Lipids with the maximum number of hydrogen atoms are referred to as saturated.
Lipid molecules that have the maximum number of hydrogen atoms possible are referred to as unsaturated?
No. Lipid molecules that are unsaturated have less hydrogen atoms because of carbon-carbon double bonds.
Manufacturers make vegetable oils solid or semisolid at room temperature by?
The process called "hydrogenation" adds chemical bonds within the oil to decrease the number of double carbon bonds, changing the fat from unsaturated (fewer hydrogen bonds) to saturated (more hydrogen bonds).Saturated fats tend to be solids.
Unsaturated and saturated fat?
Fats are made of polymers that are a attached to a sugar. A polymer is a reapting chain of carbon and hydrogen molecules. If all the molecules have hydrogens, the polymer is a saturated fat. If the chain is missing one hydrogen, it becomes an unsaturated fat. If the chain has mor than one missing hydrogen, it is a polyunsaturated fat.
What is saturated margerine?
Margarine is vegetable oil which has been hydrogenated. Oil is is unsaturated which means that the hydrocarbon chain has double bonds which can be broken and hydrogen added making the molecule saturated. Double bonds cause the molecule to be kinked which means when many of these molecules are present, they can not pack as tightly together causing oil to be liquid. Once the double bonds are broken, and hydrogen takes those spots, the molecules becomes straight. When the molecules become straight they can pack together much more tightly. This results in the oil becoming solid which is why margarine is a solid.
