Examples: lecithin, ergosterol.
Any lipid that is hydrogenated. Having single carbon carbon bonds lets all the hydrogen bond and allows the lipid to remain a solid at room temperature.
It all depends on which molecule you have.
Double bond!!
No, you have misunderstoof the definitions. An oil is a lipid that is liquid at room temperature and a fat is a lipid that is solid at room temperature, therefore by definition a fat cannot be an oil at room temperature.
No.See the Related Questions link to the left for more information about how to determine if any molecule is polar or not.
Hydroxide does not usually exist on its own; it is either part of a solution, a usually solid compound, or possibly a liquid molecule.
At room temperature, calcium is solid.
Pure iodine at room temperature is a highly volatile solid.
They are called fats {not quite the same as a fatty acid} - and they are from animal origins. They are saturated - in space they are straight like a tooth pick [and they stack pretty much like a box of tooth picks]. When C=C double bonds are included, the Lipid becomes unsaturated which gives the lipid a 'dogs leg' bend - called Oils, they do not then conform into a solid as easily as they did when they were saturated {and are liquid at room temperature}.
Carbon, at room temperature, is a solid. Gaseous carbon would have to be at an extremely high temperature. Usually, carbon exists as a gas in the form of a different molecule i.e. carbon dioxide, carbon monoxide etc.
Pure lye is a solid at room temperature, but it is usually sold as a concentrated aqueous solution.
Yes, at room temperature.
