Pectin decreases the heat coagulation of many proteins, including the soluble proteins of pea stems, ovalbumin, and bovine serum albumin. This observation probably explains the decrease in heat coagulation of proteins from pea stems following in vivo auxin administration, since auxin causes a great increase in the soluble pectin content of treated cells.
