The storage of triacylglycerols in animals and plants

Although adipose tissue contains many types of cells, the ones responsible for fat storage are the adipocytes which are bound together with connective tissue and supplied by an extensive network of blood vessels. 

3 Storageoftriacylglycerols in oil seeds some plants use lipids as a fuel, which is stored as minute globules in the seed 

There are many hundred varieties of plants known to have oil bearing seeds, but only a few are significant commercially. They are the soya bean, cotton, groundnut (peanut), sunflower, coconut, oil palm, olive, sesame, rapeseed, cocoa bean, linseed, castor and tung. The first ten are important sources of edible oils for human foods or animal feeds, while the last three are used for 

Kernel with endosperm (contains palm kernel oil) 

A closer parallel to the seed oil bodies in the animal kingdom is found in the cells of the brown adipose tissue which are packed with small discrete oil droplets, 1-3 jum in diameter. These cells contain a large number of specialized mitochondria, adapted for oxidizing the fatty acids from the oil droplets which they surround. Similarly, seed oil bodies are surrounded by glyoxysomes which, during seed germination, receive fatty acids from the oil bodies for oxidation prior to the synthesis of carbohydrates, which occurs actively at this time.
