Carbs 3 functions
E source, E storage, cell structure
Lipid (fats) functions
E source, E storage, act as cytokines, form structures like cell membranes
Protein functions
Form structural aspects of cells, act as receptor, transport, “cytokines”, enzyme
Nucleic acid functions
Genetic material, form structure components of cells (ribosomes)
