Which of the following is true for lipids?
a) Lipids are hydrophobic in nature.
b) Lipids are soluble in organic solvents.
c) Fats are a type of lipids.
d) Olis contain unsaturated fatty acids.
e) All statements about lipids are correct.
Answer: e) All statements about lipids are correct.
Lipids are a group of natural products that are fat soluble and insoluble in water but soluble in non-polar solvents. This is because molecules of both of these substances do not readily dissolve in water; their molecular structure is of non-polar carbon-hydrogen bonds. Some of the classifications of lipids include fats and oils, waxes, steroids and Isomers. There are different types of lipids and fats are one of them; these are lipids which solidify at room temperature and include saturated fatty acids. On the other hand, oils contain unsaturated fatty acids and are in a liquid state when at room temperature. Everything mentioned about lipids in these statements is quite precise and provides a proper description of the characteristics that should be attributed to the biomolecules that are part of this class.
