Nucleic Acids = stores hereditary material Proteins = structural support, protection, transport, catalysis, defense, regulation and movement CBH = source of energy (glucose) and carbon skeletons for structure and support (cellulose, chitin makes up external skeleton of insects and crustaceans) Lipids = Stores energy, phospholipids = structural role in cell membr, thermal insulation (blubber), steroids = regulatory role as hormones and vitamins, lipid coating around nerves = electrical insulation, oil or wax in feathers, skin, fur repels water.

TG of animal fats = long chained and saturated FA, packed together tightly Therefore = solid at RT and have high melting point TG of plants tend to have short or unsaturated FA, DUE TO KINKS = pack together poorly = low melting point = liquid at RT
