The plasma membrane of a cell is extremely important to the transportation of substances into and out of the cell. The outer membrane of a cell is made up of lipids and proteins. Most of the lipids in plasma membranes are phospholipids. The phospholipids have a hydrophilic head and two hydrophobic tails. When engulfed in water‚ they arrange themselves such that all the hydrophobic tails clump together‚ surrounded by the hydrophilic heads‚ protecting the tails from the exposure to the water. In cells

plausible mechanism was suggested in Time by Dr. Michael Brownlee of Albert Einstein College of Medicine in New York City (November 26‚ 1990‚ p. 52-59). Glucose is known to be chemically active and can form a temporary bond with many proteins‚ including hemoglobin.

Brownlee suggests that this superglue is a "source of constant irritation"
