Relating to or promoting gluconeogenesis, the metabolic process where the body creates glucose from non-carbohydrate sources like proteins and fats.
From gluconeogenesis (glucose + neo- 'new' + genesis 'origin'), combined with -genic 'producing' from Greek genos 'birth.' The term emerged in 20th-century biochemistry to describe pathways that synthesize glucose anew.
Your liver performs gluconeogenic magic during fasting or intense exercise—it literally builds new glucose molecules from scratch using amino acids and glycerol, keeping your brain supplied with fuel even when you haven't eaten in hours. This is why prolonged starvation doesn't immediately shut down your thinking, even though it feels miserable.
