Amino acids are matched with each individual mrna molecule and folded within themselves into protein. Needs to be extra large so it can help support a potential fetus. Longest cells are nerves (spine to big toe) Lipids: hydrocarbon chains compose membranes, fat for storage, hormones (steroids: cholesterol in membranes allow it to stay fluid at lower temperatures (animals in cold climates have lots of cholesterol) Cytoskeleton: microtubules tubulin structure, attach to kinetochores, track for organelles, cilia & flagella, microfilaments actin structure & support, cytokinesis, microvilli. Intermediate filaments keratin structure & strength.
