* Certain metabolic diseases may result in deranged carbohydrate metabolism.

~~for the production of energy needed by the cells, and this~~ leads to fatty change.

* Glucose is not made available for uptake into the tissues.

Examples ~~are~~ Diabetes mellitus in dogs ~~where there is a deficiency~~ of the hormone insulin

** The celles still require energy, and so alternative pathways are resorted to.

** Ketosis in ruminants

+

*** The body is exhorted to find another source of energy following drainage of the glucose reserves.

+

**** Fat reserves are mobilised and transported to the liver.

*** E.g.

+

**** Twin lambs in sheep

***** The condition is known as Pregnancy Toxaemia

**** Milk producion in high-yielding dairy cattle shortly afer parturiton.
