In [[enzymology]], a '''L-arabinose 1-dehydrogenase''' ({{EC number|1.1.1.46}}) is an [[enzyme]] that [[catalysis|catalyzes]] the [[chemical reaction]]
:L-arabinose + NAD<sup>+</sup> <math>\rightleftharpoons</math> L-arabinono-1,4-lactone + NADH + H<sup>+</sup>
Thus, the two [[substrate (biochemistry)|substrates]] of this enzyme are [[L-arabinose]] and [[nicotinamide adenine dinucleotide|NAD<sup>+</sup>]], whereas its 3 [[product (chemistry)|products]] are [[L-arabinono-1,4-lactone]], [[nicotinamide adenine dinucleotide|NADH]], and [[hydrogen ion|H<sup>+</sup>]].
This enzyme belongs to the family of [[oxidoreductase]]s, specifically those acting on the CH-OH group of donor with NAD<sup>+</sup> or NADP<sup>+</sup> as acceptor. The [[List of enzymes|systematic name]] of this enzyme class is '''L-arabinose:NAD<sup>+</sup> 1-oxidoreductase'''. This enzyme participates in [[ascorbate metabolism|ascorbate and aldarate metabolism]].
