Serum cholinesterase has been previously shown to complex with beta-lipoprotein in the plasma. Since serum cholinesterase exists as isoenzymes in plasma, the relationship between the activity of these isoenzymes (unbound to beta-lipoprotein) and lipoprotein titer was investigated. The results indicated that the total of C2, C3, and C4 isoenzyme activities were expressed within a narrow range and independent of low density lipoprotein titer. These findings may indicate that unbound plasma cholinesterase may undergo autoregulation independent of cholinesterase bound to beta-lipoprotein.
