      the liver and the adipose tissue. Fatty acids synthe-sized in the liver are exported through lipoprotein production, and thus provide an energy source and structural components for membrane building. In adipose tissue, De novo synthesis of fatty acids directly contributes to in situ fat deposition and long-term energy storage.

      The adult liver fluke, Fasciola hepatica, inhabits the bile duct of its final host, usually cattle or sheep. The veterinary aspects of infection with F. hepatica can represent a major ... There is no evidence that this pathway is of significance in energy metabolism; only about one-tenth of the catabolized carbohydrate is shunted via this pathway.

      Energy Availability and Alcohol-Related Liver Pathology Carol C. Cunningham, Ph.D., and Cynthia G. Van Horn, Ph.D. Alcohol consumption alters the metabolism of the most common type of cell found in the liver, the hepatocyte. The presence of alcohol in the body causes the liver to use more oxygen—for example, when breaking down the alcohol.

The single most important nutrient required for milk synthesis is glucose, yet nearly all glucose consumed by the dairy cow is degraded in the rumen to volatile fatty acids which are absorbed and delivered to the liver. The liver is responsible for converting propionate from glucose
