Can proteins be saturated or unsaturated?

Once the channels operate at their maximal rate, a further increase in particle numbers no longer increases the apparent rate of diffusion. At this limited rate we describe the protein channel as being saturated.

Can lipids be saturated or unsaturated?

Fats may be saturated (having single bonds) or unsaturated (having double bonds). Unsaturated fats may be cis (hydrogens in same plane) or trans (hydrogens in two different planes).

When the carrier is saturated (that is, when all solute-binding sites are occupied), the rate of transport is maximal. This rate, referred to as Vmax, is characteristic of the specific carrier and reflects the rate with which the carrier can flip between its two conformational states.
