Adipose tissue is a highly specialized loose connective tissue designed to store large quantities of triacylglycerols (triglycerides) and fat-soluble substances. It is classified as a connective tissues due, in part, to the fact that its is derived from embryonic mesenchyme.Each adipose cell, or adipocyte, stores lipid in cytoplasmic inclusions called lipid droplets. Two types of adipose tissue are found in animals: white adipose tissue and brown adipose tissue.Brown adipose tissue is present in significant amounts in human infants.hite adipose tissue is the principal type of adipose tissue of the adult human. The tissue, which is scattered about the body, occupying positions in skin and around and within a variety of other organs, is itself a large, physiologically important organ.
