*function - easy access energy storage !

- hydroxyl & carbonyl groups make them polar

- monosaccharide : single unit of carbohydrate.
eg. glucose C6 H12 O6 (isomer)

- disaccharide : 2 monosaccharides bonded tgt 
eg. lactose (galactose+glucose)

- polysaccharide : polymer made of repeating subunits of monosaccharides 
eg. amylose

*function - energy rich because C-H bonds make it an efficient long term storage molecule !

* due to long chains of C-H bonds, lipids r non-polar.

function - structural support for the bone, hair, tendons, skin etc

transporters- in cell membranes (protein channels) & in the blood.

eg of :
polar - serine, theorine
non polar - glycine, alamine
electrically charged - aspartic acid (acidic), lysine (basic)
