Production of Lactate

[mathsphd]

Hi All,

I have searched the litreture for means of lacate production other than from glycolysis and didn't seem to find another way in which lactate is produced inside the cell. Please if you happen to know otherwise let me know. Also, lactate is shown to enhance cell migration and it can be utilised as an energy source in embroys.
Is it used up in any other normal cellular function?

I also found that the half life of lactate is 60 minutes after exercise and 18 hours after shock. But, couldn't find its half-life in a normal functioning cell . Any hints?

My background is not biology and so it would be grateful if you provide some hints or confirmations.

Cheers
Mary

look up the cori cycle. Lactate is recycled to the liver where it can be used in gluconeogenesis to regenerate glucose...
