Transcript of Wax Molecules

By Annika Norden and Bailey Sherwin Organic Molecules Project: The Wax Molecule LIPIDS: Function: R1 can be 6-16 extra carbon Structure: Easy material to mold - Ideal for:
Waterproofing Importance: Animals:
Birds - wax in/under feathers.
Waterproofs - Protects Examples: Important Info: Questions? Thank you! Waterproof barrier
Repel/retain water
ex: plant leaves Completely water-insoluble

Generally solid at biological temperatures.

Plant waxes are most abundant of all natural lipids.

Derives from the old English word "weax"
"the honeycomb of the bee hive"

Ear wax vary from other waxes
Made up of phospholipids and esters of cholesterol R2 can be 8-16 extra carbon R3 is 16-20 extra carbon Comprised of an ester of a long chain of alcohol and fatty acids
Made up of many different things such as: hydrocarbons, sterol esters, aliphatic aldehydes, primary and secondary alcohols, diols, ketones, -diketones, triacylglycerol *The chain length
can vary on what type
of wax it is. Candles are a common use of wax.
Types of wax that are used for candles are Paraffin wax
Melting point of about 130 degrees
Soy wax and Bee's wax are also used Used in cosmetics such as mascara and lipstick.
The most commonly found wax in makeup is bee's wax
Bee's wax increases the thickness in the lipid.
Gives a structure for easy application.
Used in eye makeup to thicken and waterproof the makeup. Ways humans use wax: Humans:
Produce wax in ears Saturated Fats
Unsaturated Fats
Waxes Plants:
Thin layer of waxy material Protect humans
Infections in ears
In the outer canal
gland in ear
produces wax
keeps ear free of fungus and infections. Plant Surface Waxes:
(Thin layer of waxy material)
Limits the diffusion of water and solutes
Permits a controlled release of volatiles
Provides protection from disease and insects
Helps the plants retain water

Insect Waxes:
Restricts movement of water across the cuticle
Prevents desiccation

Marine Waxes:
Serves as an energy source to insulation, buoyancy and echo location

Bird Waxes:
Gives a water-proof layer to feathers Bibliography: Bailey, Regina. "Lipids." About.com Biology. N.p., n.d. Web. 18 Sept. 2012. <http://biology.about.com/od/molecularbiology/ss/lipids.htm>.

Protects birds against wetting
Makes feathers felixible
Plays a role as antiparasitic compounds
Provide UV protection
And more Diester Waxes Acids of wax esters may have a mono- or multi-branched chain Diester Wax Structure Long chains of carbon
Little oxygen
