How can fatty acids become phospholipids?

Answer 1

A phospholipid is similar to a triglyceride, except that a phosphate group replaces one of the fatty acids, so that two fatty acids and one phosphate group bond with a glycerol molecule. The phosphate head is polar and hydrophilic, while the fatty acid tail is nonpolar and hydrophobic. All cell membranes consist of a phospholipid bilayer, in which the phosphate heads are oriented either to the aqueous extracellular fluid, or the aqueous intracellular fluid. The fatty acids are sandwiched in between.

The R attached the the phosphate group represents any of a number of organic molecules that can attach to the phosphate group. One example is choline.

Fatty acids can become phospholipids through esterification with glycerol, forming a glycerophospholipid.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
