Most organisms store lipids and/or carbohydrates for energy production when food is unobtainableduring fasting. Much more energy per unit mass can be stored asStorage lipids are much more energy dense than carbohydrates, but long-chain fatty acids are insoluble and must be transported as lipoproteins. Vertebrates and higher arthropods have tissues specialized for lipid storage and management of lipids. Adipose tissue can reach 50% of thehalf the body mass before migration or breeding fasts with superficial depots expanding most, especially in large animals. Adipocytes are 40-85% triacylglycerols and occur in various intra-abdominal and superficial sites in all tetrapods and some fish; some mammalian depots of mammalian adipose depots tissue have site-specific properties specialized to paracrine interactions with interchelated adjacent cells and contiguous tissues.
