Galactose 1-phosphate
Galactose 1-phosphate acts as a competitive substrate inhibitor of galactose-1-phosphate uridylyltransferase (GALT). Galactose 1-phosphate is a competitive inhibitor of Phosphoglucomutase, yet the rate at which this enzyme converts Galactose 1-phosphate to Galactose-6-phosphate is 400 times slower than the rate of converting Glucose-1-phosphate. Galactose 1-phosphate can be used in studies related to Saccharomyces cerevisiae infection and type I galactosemia.

Galactose 1-phosphate acts as a competitive substrate inhibitor of Escherichia coli galactose-1-phosphate uridylyltransferase (GALT), which can displace UMP from the covalently bound UMP-GALT intermediate to form UDP-galactose[1].
Galactose 1-phosphate acts as a competitive inhibitor of Phosphoglucomutase, yet the reaction rate at which this enzyme converts Galactose 1-phosphate to galactose-6-phosphate is 400 times slower than that of glucose-1-phosphate conversion[2].
