Fats

liquid, semi-liquid or solid components of plants or animals which are predominantly compounds of glycerol with higher fatty acids (fatty acid glycerides).

The storage of fat in reticulum cells of the connective tissue produces fat cells, their accumulation as fat tissue serves as fat store, as construction fat, as well as the regulation of the water and heat balance.
