increases
Are saturated fatty acids solid or liquid at room temperature?
solid
Unsaturated fats are different from saturated fats because they contain what type of bond?
double bond
what is the process used to make artifical trans fats?
partial hydrogenation
A lipid that is solid at room temperature is called?
a fat
These fats often have a lighter flavor and are preferred in frying because their flavor won't overpower the food.

Saturated Fats
A lipid that is a liquid at room temperature is called?
an oil
These fats are shelf stable and preferred in pastries because they provide structure and creamy mouthfeel.
Saturated fats
True or False: saturated fats have double bonds?
false they only contain single bonds

Antioxidants
What chemical feature of saturated fats causes them to be solids at room temperature?
Saturated fats have no double bonds so they are straight and can pack closely together.
What feature of an unsaturated fat's chemical structure makes them liquid at room temperature?
Double bond which creates a bend in their chemical structure.
Trans fats got their name because the hydrogens at the double bonds are located where?
diagonally across from each other
