Summary.
The Michaelis-Menten constant (KM) of fructose and oi glucose as substrate for bull spermatozoa has been measured: fructose KM = 1·04 mM, glucose KM = 0·06 mM. The saturation rate of fructose utilization was found to be 1·8 times that of glucose utilization. This is in general agreement with characteristics of hexokinases extracted from different sources.
Reproduction is committed to supporting researchers in demonstrating the impact of their articles published in the journal.
The two types of article metrics we measure are (i) more traditional full-text views and pdf downloads, and (ii) Altmetric data, which shows the wider impact of articles in a range of non-traditional sources, such as social media.
