Peanut oil contains a high percentage of monounsaturated triacylglycerols (having acyl chains with only one double bond), whereas vegetable oil contains a higher percentage of polyunsaturated triacylglycerols (having acyl chains with more than one double bond). a bottle of peanut oil and a bottle of vegetable oil are stored in a pantry with an outside wall. during a cold spell, the peanut oil freezes but the vegetable oil remains liquid. explain why.

On other hand, higher percentage of polyunsaturated triacylglycerols (having acyl chains with more than one double bond), as in case of vegetable oil, have single or multiple double bonds in tandem. Due to these bonds, the successive layers of vegetable oils are not able to properly align with respect to adjacent layers. Hence, they low melting points. Due to this,  they remain liquid state, even in cold conditions. 

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
