Which of the following would yield the most highly mobile phospholipid in a membrane (listed as number of carbons and number of double bonds, respectively)? A) 24 carbons with one double bond B) 14 carbons with two double bonds C) 20 carbons with two double bonds D) 16 carbons with no double bonds E) 20 carbons with no double bonds

There are two properties of phospholipids that affect how tightly they pack together: the length of the hydrocarbon chain and the number of double bonds. The degree of packing, in turn, influences the relative mobility of these molecules in the membrane. Which of the following conditions would yield the greatest mobility, that is, the lowest transition temperature? Long fatty acids (20-22) with 1 double bond Short fatty acids (14-16) with no double bonds Long fatty acids (20-22) with no double bonds Short fatty acids (14-16) with 1 double bond
Dr. Anas S.
If incorporated into a phospholipid, which fatty acid listed below would provide the highest mobility to the phospholipid? a. 15 carbons with two double bonds b. 16 carbons with no double bonds c. 14 carbons with two double bonds d. 22 carbons with one double bond
