Specialized for energy stored as lipid droplets: specifically if we talk about lipids: triglycerides. Functions lipids are high density energy store lipids stored are either (cid:272)o(cid:373)i(cid:374)g fro(cid:373) the diet or they"re i(cid:373)(cid:373)o(cid:271)ilized through the liver: can be stored or can be mobilized (taken out of storage) Energy storage function (adipose tissue: thermogenesis (brown fat) heat generation, forms a cushion (around the heart for example adipose tissue cushions the heart) Associated with skin and your heart: insulation. Skin and heat retention you"re (cid:374)ot a(cid:272)tually looki(cid:374)g at fat; you look at the space left behind. Single droplet want to take fat out of storage. Droplets are present as single, large droplets (unilocular) vascularized (figure a: blood vessels) when looking at tissue with lots of adipose sites the lipids are extracted leaving lots of empty spaces (during processing for paraffin embedding)
