  • Title: Effect of alpha-chlorohydrin on glucose metabolism by spermatozoa from the cauda epididymidis of the rhesus monkey (Macaca mulatta).
    Author: Ford WC, Harrison A.
    Journal: J Reprod Fertil; 1980 Sep; 60(1):59-64. PubMed ID: 6776277.
    Abstract:
    Spermatozoa from the cauda epididymidis of the rhesus monkey had metabolic properties similar to those published for ejaculated spermatozoa. The concentration of glycolytic intermediates was low until 2 mM-glucose was added; glucose 6-phosphate, fructose 1,6-bis-phosphate and the triose plhosphates then increased but glycerate 3-phosphate did not. It was concluded that the activity of glyceraldehyde 3-phosphate dehydrogenase (EC 1.2.1.12) limited flux through the glycolytic pathway. The production of lactate and CO2 from glucose was strongly inhibited in the presence of 5 or 10 mM-alpha-chlorohydrin. The energy charge of the spermatozoa was low before and after 1 incubation with 2 mM-glucose (0.5 +/- 0.05 and 0.05 +/- 0.06 respectively) and the value after the incubation was decreased in the presence of 5 or 10 mM-alpha-chlorohydrin (0.17 +/- 0.05 and 0.15 +/- 0.04 respectively). alpha-Chlorohydrin inhibited glycolysis at the glyceraldehyde 3-phosphate dehydrogenase reaction.
