Although free IAA is the biologically active form of the hormone but toxic in high concentration, the vast majority of auxin in plants is found in a covalently bound state are considered hormonally inactive.

IAA has been found to be conjugated to both high- and low-molecular-weight compounds.

Low-molecular-weight conjugated auxins include esters of IAA with glucose or myo-inositol and amide conjugates such as IAA-N-aspartate.

High-molecular-weight IAA conjugates include IAAglucan

The rate of sedimentation is dependent not only upon the applied centrifugal field, but
also on the nature of the particle, i.e., its density and radius, and also the viscosity of the
surrounding medium. Stokes’ Law describes these relationships for the sedimentation of a
rigid spherical particle:

Mutants that cannot be expressed at all are called uninducible. Mutants that are continuously expressed are called constitutive mutants.
