Pathway: Metabolism (Homo sapiens)
Metabolic processes in human cells generate energy through the oxidation of molecules consumed in the diet and mediate the synthesis of diverse essential molecules not taken in the diet as well as the inactivation and elimination of toxic ones generated endogenously or present in the extracellular environment. The processes of energy metabolism can be classified into two groups according to whether the

Pathway: Developmental Biology (Homo sapiens)
As a first step towards capturing the array of processes by which a fertilized egg gives rise to the diverse tissues of the body, examples of three kinds of processes have been annotated. These are aspects of the roles of cell adhesion molecules in axonal guidance and myogenesis, of transcriptional regulation in hematopoiesis (specifically, B lymphopoiesis), pancreatic beta cell and whit

Pathway: Hexose transport (Homo sapiens)
Hexoses, notably fructose, glucose, and galactose, generated in the lumen of the small intestine by breakdown of dietary carbohydrate are taken up by enterocytes lining the microvilli of the small intestine and released from them into the blood. Uptake into enterocytes is mediated by two transporters localized on the lumenal surfaces of the cells, SGLT1 (glucose and galactose, together with sodium ions

Pathway: SLC-mediated transmembrane transport (Homo sapiens)
Proteins with transporting functions can be roughly classified into 3 categories: ATP-powered pumps, ion channels, and transporters. Pumps utilize the energy released by ATP hydrolysis to power the movement of the substrates across the membrane, against their electrochemical gradient. Channels at the open state can transfer the substrates (ions or water) down their electrochemical gradient, at an extre

Pathway: Metabolism of carbohydrates (Homo sapiens)
These pathways together are responsible for: 1) the extraction of energy and carbon skeletons for biosyntheses from dietary sugars and related molecules; 2) the short-term storage of glucose in the body (as glycogen) and its mobilization during a short fast; and 3) the synthesis of glucose from pyruvate during extended fasts

Pathway: Regulation of beta-cell development (Homo sapiens)
The normal development of the pancreas during gestation has been intensively investigated over the past decade especially in the mouse (Servitja and Ferrer 2004; Chakrabarti and Mirmira 2003). Studies of genetic defects associated with maturity onset diabetes of the young (MODY) has provided direct insight into these processes as they take place in humans (Fajans et al. 2001). During embryogenesis, com

Pathway: Regulation of Glucokinase by Glucokinase Regulatory Protein (Homo sapiens)
Glucokinase (GCK1) is negatively regulated by glucokinase regulatory protein (GKRP), which reversibly binds the enzyme to form an inactive complex. Binding is stimulated by fructose 6-phosphate and sorbitol 6-phosphate (hence high concentrations of these molecules tend to reduce GCK1 activity) and inhibited by fructose 1-phosphate (hence a high concentration of this molecule tends to increase GCK1 acti

Pathway: Glucose metabolism (Homo sapiens)
Glucose is the major form in which dietary sugars are made available to cells of the human body. Its breakdown is a major source of energy for all cells, and is essential for the brain and red blood cells. Glucose utilization begins with its uptake by cells and conversion to glucose 6-phosphate, which cannot traverse the cell membrane. Fates open to cytosolic glucose 6-phosphate include glycolysis to y
