Final answer:
Both odd chain fatty acids and even chain fatty acids can produce glucose under certain conditions through a process called gluconeogenesis.
Step-by-step explanation:
Both odd chain fatty acids and even chain fatty acids can produce glucose under certain conditions. Odd chain fatty acids are normally oxidized through beta oxidation, which produces acetyl-CoA and propionyl-CoA. The propionyl-CoA can be further oxidized to produce glucose through a process called gluconeogenesis. Even chain fatty acids can also be converted into glucose through gluconeogenesis when glucose levels are low.
