Cancer cells primarily use glucose and glutamine as fermentable fuels, while ketones are non-fermentable.

“now it's funny i i mean I know that biochemically I'd never thought of it in those terms though yeah yeah it's not fermentable that's interesting so that's kind of what I'm thinking about you know in terms of ketone metabolism with glutamate so or glutamine glutamine can make glutamate right an alanine and aspartate and lactate and glutamine Oasis is kind of driven by the malli aspartate shuttle and that has become a major focus now of many cancer researchers are looking to target glutamine”
