Lipids (Fats)

What they do for living things

What lipids do for living things…Lipids (fats) contain a lot of energy (Calories). The body uses fat to store energy to use in the future. Fats insulate the body and cushion internal organs.Some hormones are made from lipids.

They are are called

Other types of lipids are Waxes

Oils also help to Waterproof animals continuecontinue

The natural oils on the bird’s feathers keep them dry, warm, and help keep

them afloat.

If birds already have oil on their feathers, why do petroleum oil

spills kill birds in great numbers?

When the bird’s feathers get petroleum oil

on them, they no longer are waterproof so

they absorb water and make the bird too

heavy to float. Their feathers also no longer keep them warm.

Most birds will die because they get too cold, but other birds that are on land will

usually die from eating the oil as they try to clean it off of their feathers with their beaks.

What is a way to stop this??

Is there any way to help save them?

Knit them sweaters!!

It keeps them from preening their feathers and eating the oil, so they have a

better chance of living.

This is real! Hundreds of sweaters were knit for penguins who were caught in oil spills!

Back

Although very fashionable, the penguins did have to leave their sweaters behind when they were returned to the

wild.

WAXESWaxes are often substances which are used to waterproof surfaces and/or help prevent

loss of moisture.

Fruits produce a waxy coating to keep from drying out.

Elements, monomer,

and shape

The elements found in Lipids areCarbon

HydrogenOxygen

You might have noticed that both carbohydrates and lipids have the elements Carbon, Hydrogen, and Oxygen.

A carbohydrate, has twice as many hydrogen atoms as the number of oxygen atoms.

On the other hand, lipids have a lot more than twice the amount hydrogen atoms as the number of oxygen atoms.

Which one of the following molecules is a lipid?

A carbohydrate?

1.) C12H22O11

2.) C27H46O LipidLipid

The Monomers of Lipids

The most common monomer of lipids are called

TRIGLYCERIDES

The amount of energy gained by eating lipids…

Energy Gained from Lipids

Eating 1 gram of fat provides your body with

9 Calories. Notice if you eat 1 gram of fat, you are gaining more than twice the amount of

Calories than from a gram of carbohydrate or protein!
