A generic mechanism for an acid Fischer esterification is shown below.

The general mechanism in which the material was being transferred in different states is shown pictorially below.

These two mechanisms are shown in figure 2 B and C.

The general mechanism for acidic and alkaline solutions is shown below.

A possible mechanism for the rearrangement step is shown below:

This mechanism of the ubiquinone reduction is shown in image 8.

The mechanism which forms A and B is shown below.

The proper arrow-pushing mechanism is shown in Figure 4.

A mechanism for glucopyranosides and mannooyranosides is shown below.

This legal mechanism has been shown to increase the affected patient's time out of the hospital.
