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.

Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic. The structure of the phospholipid molecule generally consists of two hydrophobic fatty acid tails and a hydrophilic head consisting of a phosphate group.The two components are joined together by a glycerol molecule.he hydrophilic head contains the negatively charged phosphate group and glycerol. The hydrophobic tail usually consists of 2 long fatty acid chains. When placed in water, phospholipids form a variety of structures depending on the specific properties of the phospholipid.
