* Carbs
Elements C(1):H(2):O(1)
Stored in carbs
** Roles of carbs
*** Monosacharide - glucose
*** Disacharides - two bonded monosacharide, e.g. sucrose
| starch | found in plants |
| glycogen | found in animal tissue |
| cellulose | |
* Fats
Elements C,H,O
** Saturated, unsaturated fatty acids
| Saturated | saturated w/ H (at every carbon bond) | only single bonds between carbons | solid @ room temp | comes from animals primarly |
| Unsaturated | not saturated w/ H | one or more double bonds (geometry changes) | liquid @ room temp | comes from plants primarily |
* Proteins (Polypeptides)
Monomer = Amino Acid
Elements C,H,O,N
Chains of amino acids
Proteins can lose shape & function (denatured) - shape determines function
** 4 cal / g
** Elements C,H,O,N
** Diverse, complex
