Short answer

The structure of ppGpp is given below:

Step-by-step solution

Definition of Concept

Small hydrophobic signaling molecules can diffuse through the plasma membrane and bind to intracellular receptors.

Draw the structure

ppGpp (guanosine-3',5'-bisdiphosphate) is a guanine analog with two phosphate groups at the 3rd and 5th carbons. The structure is as follows:
