Question

can triacylglycerols replace phospholipids in membrane​

Answer 1

The phospholipid is similar to the triglyceride in that it contains fatty acid tails attached to a glycerol backbone. However, the phospholipid contains a organic phosphate zwiterion instead of a third fatty acid tail. Triglycerides are completely insoluble in water. So not we can't replace it with phospholipids
