The main pigment of plants is "chlorophyll," which gives the green color characteristic of most vegetables, absorbs very well the light in the bands of red and violet, reflecting the green light.
The level of protein X in these patients will be low due to degradation in the proteasome. Ubiquitnation process occur when ubiquitin is attached to a particular protein and the protein become deactivated. Ubiquitin is a small biochemical molecule which marks out proteins for destruction. Any protein that have ubiquitin attached to it will be transported to the proteasome for destruction by degradation.
