In enzymology, L-rhamnose 1-dehydrogenase (EC 1.1.1.173) is an enzyme that catalyzes the chemical reaction

+ NAD+
 
 
 
H+
L-rhamnose 1-dehydrogenase
 
H+
 
+ NADH
 

The two substrates of this enzyme are L-rhamnofuranose and oxidised nicotinamide adenine dinucleotide (NAD+). Its products are L-rhamnono-1,4-lactone, reduced NADH, and a proton. [1] [2] [3]

This enzyme belongs to the family of oxidoreductases, specifically those acting on the CH-OH group of donor with NAD+ or NADP+ as acceptor. The systematic name of this enzyme class is L-rhamnofuranose:NAD+ 1-oxidoreductase. This enzyme participates in fructose and mannose metabolism.
