Glycerol enters the liver and is converted to glycerol-3-P by glycerol kinase, which is then oxidized to DHAP by glycerol-3-phosphate dehydrogenase. The labeled glycerol-3-P is in rapid equilibrium with DHAP.

27 Ιουλ 2018 · We probed multiple biochemical processes in humans with fatty liver using the enrichment and distribution of 13 C and 2 H in plasma TG-glycerol and glucose after oral administrations of [U-13 C 3]glycerol and 2 H 2 O. Subclinical hepatic steatosis was associated with enhanced and more rapid metabolism of [U-13 C 3]glycerol through pathways that ...
21 Ιουλ 2017 · The liver is crucial for the maintenance of normal glucose homeostasis — it produces glucose during fasting and stores glucose postprandially. However, these hepatic processes are dysregulated in...
Adipose tissue produces and releases nonesterified fatty acids (NEFAs) and glycerol via lipolysis. Muscle breaks down glycogen and proteins and releases lactate and alanine. Alanine, lactate, and glycerol are delivered to the liver and used as precursors to synthesize glucose (gluconeogenesis).
17 Οκτ 2024 · This work found that glycerol kinase (GK) is upregulated in diet-induced and genetic mouse models of nonalcoholic fatty liver (NAFL). Fatty acids and cholesterol stimulate GK expression in hepatocyte...
Unlike adipose tissue, liver has the capacity to phosphorylate free glycerol via glycerol kinase to yield glycerol 3-phosphate (G3P), 2 which then becomes esterified with fatty acids.
Excess glucose is used to synthesize fatty acids in the liver. In addition to glucose utilization, human liver releases glucose to the systemic circulation, either from previously stored glycogen (glycogenolysis) or by generating glucose from precursors such as alanine, lactate and glycerol (gluconeogenesis).
