| Hazard Information | Back Directory | [Uses]
The L-diastereomer of the β-lactam antibiotic Cephalexin (C256800). It is is transported by PEPT1 (the oligopeptide transporter responsible for absorption of peptide nutrients in the small intestine)
with high affinity, but is not metabolized by PEPT1 itself. | [Uses]
