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 make up an important class of lipids for the construction of cell membranes. The phospholipids are not true fats because they have one of the fatty acids replaced by a phosphate group.This sketch of a phospholipid molecule shows two fatty acids and a phosphate group attached to a glycerol backbone.Stearic acid is shown as the fatty acid, but there are many variations in the fatty acids.hospholipids make up an important class of lipids for the construction of cell membranes.
