Pro-Line is a major manufacturer of wheels, tires, accessories and bodies for 1/10-scale on- and offroad radio-controlled cars.

Proline (abbreviated as Pro or P) is an α-amino acid, one of the twenty DNA-encoded amino acids. Its codons are CCU, CCC, CCA, and CCG. It is not an essential amino acid, which means that the human body can synthesize it. It is unique among the 20 protein-forming amino acids in that the α-amino group is secondary. The more common L form has S stereochemistry.
