If you want the blood stored, after the birth, the doctor clamps the umbilical cord in two places, about 10 inches apart, and cuts the cord, separating mother from baby. Then she inserts a needle and collects at least 40 milliliters of blood from the cord. The blood is sealed in a bag and sent to a lab or cord blood bank for testing and storage. The process only takes a few minutes and is painless for mother and baby. The cord blood bank may also send tubes so that the motherâs blood can be taken, too.
Phospholipids. Phospholipids differ only slightly from triglycerides in chemical structure. While each triglyceride molecule consists of glycerol and three fatty acids, each phospholipid molecule substitutes a phosphate for one of the three fatty acids.Phospholipids form the membrane that make up the outer layer of all human cells.hospholipids.

Lipid Bilayer. Lipid Bilayer Phospholipids make up the basic structure of a cell membrane. Phospholipids are more polar than the lipids discussed thus far (triglycerides), because they contain a phosphate group bound to an amino alcohol unit in place of one of the ester linkages of a triglyceride.n the lipid bilayer, the polar âheadsâ of the phospholipids are arranged so as to interact with the aqueous environments on the inside and the outside of a cell, while the nonpolar âtailsâ coagulate together to form a nonpolar bilayer.
