L-2-Aminobutyric acid is one of the three isomers of aminobutyric acid, and its levels are significantly elevated in the plasma of organisms with metabolic disorders such as Reye's syndrome, tyrosinemia, homocystinuria, nonketoglycosuria, and ornithine transaminase.

| Weight (kg) | 0.02 | 0.15 | 1.8 | 0.4 | 0.08 | 10 |
| Body Surface Area (m2) | 0.007 | 0.025 | 0.15 | 0.05 | 0.02 | 0.5 |
| 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.
