It probably does not surprise you that the major function of the adipose is to store energy as triglycerides. Compared to extrahepatic tissues as a whole, in the adipose the following pathways are not performed or are not important:<\/p>\n

Glycogen synthesis and breakdown<\/p>\n

Lactate synthesis<\/p>\n

Ketone body breakdown<\/p>\n

Fatty acid breakdown<\/p>\n

Protein synthesis and breakdown<\/p>\n

Citric acid cycle (not much since it is not an active tissue needing energy)<\/p>\n

These pathways are crossed out in the figure below.<\/p>\n
