Tetrahydrofolic acid (L-5,6,7,8-Tetrahydrofolic acid) is the biologically active vitamin B9 folate derivative. Tetrahydrofolic acid is a donor of one-carbon groups for amino acids, nucleic acids, and lipids. Tetrahydrofolic acid serves as an acceptor of free formaldehyde, producing 5,10-methylenetetrahydrofolate-Tetrahydrofolic acid.

| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
