BIOL 1201 Lecture : Lecture 4
Document Summary
When combining two saccharaides, c6h12o6, you take away an h2o due to synthesis. Energy roles: metabolic fuel: glucose(human) and sucrose(plant, storage form: starch(plants) and glycogen(human, structural: cellulose in the plant wall and chitin forms shells for crabs and shrimp. Water-insoluble organic biomolecules and made up of non-polar groups. They are hormones that are only lipids as well. Saturated fats tend to be sold while unsaturated tend to be liquid. Saturated: saturated with h, no double bonds between adjacent carbons. Unsaturated is much better for you than saturated. Saturated fats are bad because they raise ldl cholesterol. Saturated fat is a linear type of molecule while unsaturated fats have a kink in the molecule, requiring it to have to lower the temperature to become a solid. Saturated fats are solids at higher temperatures than unsaturated. Acyl chains of unsaturated fats are kinky and therefore require a lower temperature to become a solid. Artic fish have more unsaturated fats than tropical fish.
