Lipids: Fats & Oils & Wax & Steroid

AP Biology Lipids: Fats & Oils AP Biology Lipids energy storage.

AP Biology Intro to Organic Molecules & Lipids AP Biology Life is based on Carbon Carbon atoms are versatile building blocks Special bonding properties.

Lipids – Fats and Oils. Lipids – Good Fat / Bad Fat  Non polar  Derivative hydrocarbons (mostly C and H with some O)  Due to the large number of C-

Lipids (a.k.a. fats).

Fats and Lipids.

Examples Fats Oils Waxes Steroids Functions Long-term energy storage Main component of cell membranes Hormones Insulation/cushioning.

Fats (an example of a lipid) Glycerol – Has three –OH groups – Polar molecule Soluble in water Fatty Acids – Long chains of hydrocarbons Insoluble in water.

LIPIDS Learning Targets: #6 - #9 All the facts…. Lipids ELEMENTS: C, H(many), O (few) H:O ratio much greater than the carbohydrates FUNTIONAL GROUPS:

Lipids Hydrophobic Elements: C H O Ratio of H:O= H greater than O C 57 H 110 O 6.

Lipids Monomers – fatty acids & glycerol Function- repel water, insulate, store the greatest amount of energy compared to other macromolecules Found in.

Lipids. Include fats, oils, waxes, and steroids –All hydrophobic Consist of 1 glycerol molecule and 3 fatty acids. –Glycerol is an alcohol –Fatty acid.

Lipids long term energy storage concentrated energy.

What makes McDonald’s fries taste SOOOO good?. Lipids Lipids are composed of C, H, and O Greater H:O ratio than 2:1 Primary function is energy storage.

LIPIDS SECTION 1-8 P CHARACTERISTICS MADE UP OF C, H, O BUT H TO O RATIO IS NOT 2:1 THE MONOMER IS THE FATTY ACID (ALONG WITH GLYCEROL)

LIPIDS --- Fats & Oils. LIPIDS include: fats oils cholesterol phospholipids.

Lipids LONG TERM ENERGY STORAGE. What elements are lipids composed of? 1. Carbon (C) 2. Hydrogen (H) 3. Oxygen (O) Top left hand corner of your notes.

Mmmm… LIPIDS!. What’s the connection? FATS CAN BE … BOTH GOOD AND BAD!

Lipids 11/04/10. –Many contain carbon chains called fatty acids (monomer). –Fats and oils contain fatty acids bonded to glycerol. –Do not dissolve in.

LIPIDS The Molecules of Cells CH 3. Lipids Lipids include fats, which are mostly energy-storage molecules Lipids include fats, which are mostly energy-storage.

Lipids. Mostly carbon and hydrogen Fats, oils, and waxes Can be used to store energy  Also, part of cell membrane, and waterproof coverings, steroids,

Learning Outcomes: B4 Describe chemical structure of lipids compared to carbohydrates Recognize structural diagrams of: glycerol, saturated and unsaturated.

How do animals stay warm in chilly waters? Blubber - a thin layer of adipose (fat) tissue. Helps to insulate an animal’s body.

Lipids!. Lipids… We will focus on two kinds: fatty acids and phospholipids. ◦ Others are waxes and steroids No real monomers or polymers.

Lipids. peanut butter is 51% fat Lipids Lipids include commonly called substances - fats, oils, waxes, steroids & phospholipids They are made almost.

 Also known as fats  Made of carbon, hydrogen, and oxygen  When your body breaks down lipids, it turns it into fatty acids and glycerol.

LIPIDS

What are some examples of Lipids? (This is just funny because of lipids!)

How do animals stay warm in chilly waters? What are some examples of Lipids? How do animals stay warm in chilly waters? Blubber - a thin layer of adipose (fat) tissue. Helps to insulate an animal’s body. Blubber is fat tissue made up of lipids.

What else is made of lipids? BUTTER WAX OIL What else is made of lipids? Cell Membrane Hormones

Lipid Basics A Fatty Acid! A Triglyceride Lipids are FATS!!!! Made of C,H, & O. They are Hydrophobic/Nonpolar What is the monomer for lipids? A Fatty Acid! or A Triglyceride (Glycerol & 3 Fatty Acids)

What functional groups do you see? Carboxyl group Methyl group

Where are lipids made in the cell? The Smooth Endoplasmic Reticulum (SER)! This is the tunnel like section around the nucleus that doesn’t have any bumps

There are 3 types of Lipids Triglycerides/Fats – Used for LONG term energy storage, insulation/protection

There are 3 types of Lipids 2) Phospholipids – Used in cell membranes What is the purpose of the cell membrane? Regulating what comes in/out of the cell (it is semipermeable)

There are 3 types of Lipids 3) Steroids – Used for fat soluble vitamins (A,D,E and K) and hormones What are hormones used for? Cell Signaling (cell texting – long distances)

Fatty acids can either be saturated or unsaturated Types of Fatty Acids Fatty acids can either be saturated or unsaturated Unsaturated fatty acids have a double bond which causes a kink in the chain. This makes them liquid at room temp and easier to break up in the body which is why they are better for you.

Phospholipid Types of Fatty Acids Phospholipids are the main component of the cell membrane. They are made up of a phosphate group, a glycerol, a saturated fatty acid and an unsaturated fatty acid. Phospholipid

Dehydration synthesis How are lipids assembled? Dehydration synthesis How are lipids pulled apart? Hydrolysis

Build these 2 Lipids! A Phospholipid A Triglyceride
