4 Main Organic Compounds

Why do athletes consume protein shakes / powdersafter a workout?

• PROTEIN DOES NOT GIVE YOU ENERGY!!! This is why it is consumed AFTER a workout, not before!

• Protein is the basic building material for living things – that includes muscles.

• After a workout, there are tiny microscopic tears in the muscles... a meal in protein will help rebuild those muscles!

II. How does synthesis provide important organic macromolecules using six essential elements?

A. CarbohydratesMonosaccharides are organic compounds made of

carbon, hydrogen, and oxygen in a 1:2:1 ratio. Many monosaccharides bond together forming a larger compound chain called a carbohydrate (polysaccharide).


A. CarbohydratesIn plants the

monosaccharide called glucose (C6H12O6) bonds with other glucose molecules again and again to form starch or cellulose.

A. CarbohydratesThe plant can use

starch as food (like the “white” or a potato) and cellulose to build the stem and leaves.


A. CarbohydratesIn animals excess glucose

bond together to form a compound (similar to starch) called glycogen which is used for short-term energy storage (or long-term energy use). Glycogen is found in the liver and muscles.

Examples: Monosaccharide

Glucose Fructose (in fruit) Galactose

Disaccharide Sucrose (table sugar) Lactose (milk sugar)

Polysaccharide Starch (in plants) Cellulose (in plants) Glycogen (in animals)

1. Energy is released when carbohydrates are digested. This is because glucose is used for cellular respiration.

Functions of carbohydrates

Monosaccharides (simple sugars) provide an immediate energy source (short-term energy use)

Starch and glycogen are considered short term energy storages (or long-term energy use) because these chemicals can be broken down over a period of minutes, hours or days to provide glucose for energy.


2. Some carbohydrates are very stable and can be used for structure and support in the cell and body (cellulose in the cell wall of plant cells).


3. Carbohydrate chains on the surface of cell membranes are used as identifiers (like name tags).

Benedicts solution: simple sugar (monosaccaride). Glucose, fructose, galactose

Benedict's solution is used to test for simple carbohydrates. Benedict's solution is a blue colored liquid that contains

copper ions.

Iodine: Complex Sugar (polysaccaride) Starch

How does synthesis provide important organic macromolecules using six essential elements?

B. Lipids There are several types of lipids, but all contain subunits of

glycerol and fatty acids made of carbon, hydrogen, and oxygen. It is different from a carbohydrate because of the ratio and because the smaller units do not link together to form a chemical chain

Drawing of lipid subunit:

How does synthesis provide important organic macromolecules using six essential elements?

B. Lipids Fats can be saturated

(usually solid at room temperature) or unsaturated (usually liquid).

Phospholipids also contain a phosphate group and make up most of the cell membrane.

Steroids are lipid rings and help regulate the organism through cell communication (act as hormones)

1. Because of the numerous bonds and the way the body stores lipids, they can be used as very long-term (weeks, months) energy sources. (energy storage)

Ex. Bears accumulate a layer of fat before winter (when food will be less available)

Functions of lipids

2. Fats stored in the body act as insulation and protection for internal organs.

4. What are the two subunits found in all lipids? GLYCEROL & FATTY ACIDS


A. Nucleic AcidsNucleotides are

compounds made up of carbon, hydrogen, oxygen, nitrogen and phosphorus. Many nucleotides bond together to make up a long chain called a nucleic acid. There are two basic types of nucleic acids:


DNA is a double chain of nucleotides found in all living cells.

RNA is a single chain of nucleotides that provides the structures needed for the cell to make proteins.

1. DNA makes up the genes. Genes determine traits, such as hair color. Genes are passed from parent to offspring.

Functions of nucleic acids

2. DNA controls cellular activities by controlling the production of proteins in response to hormones and other cellular signals.


3. RNA is used in the production of proteins.

D. Proteins (made of CHON)All six essential elements may be used in the production

of small subunits called amino acids. There are 20 different amino acids, each with a specific side chain of chemicals. Amino acids bond to other amino acids to form a long chain called a protein. These chains of amino acids fold into a particular shape. The shape of a protein will determine its function.


D. ProteinsIf a protein denatures (loses its shape) it can no longer

function.

II. How does synthesis provide important organic macromolecules using six essential elements?Hemoglobin is

a protein shaped to hold oxygen for transport through the bloodstream.


A group of proteins called enzymes are shaped to fit and react with specific molecules.

1. Some proteins, called pigments, absorb and reflect light. They also create color by reflecting light. Ex. Chlorophyll

absorbs light to gather energy for photosynthesis, and reflects the color green

Functions of proteins

2. Some proteins are constructed by cells to bind with and inactivate foreign particles in the body. These are called antibodies.


3. Proteins may form structures in an organism – such as keratin (a protein) in hair and nails.

Protein also makes

muscle


4. Some proteins are used for transport through the cell membrane or in the bloodstream (ex. hemoglobin)

Functions of protein

5. Some proteins are used for communication between cells. These may be hormones (insulin) or neurotransmitters. Insulin is secreted by the pancreas and is required by the cells of the body in order for them to remove and use glucose from the blood. Insulin can be used to treat diabetes.


6. Enzymes (a special class of protein) act to speed up chemical reactions, helping to maintain homeostasis.

Buiret solution is a blue liquid that changes to purple when proteins are present and to pink in the presence of

short chains of polypeptides. The copper atom of the biuret solution

reacts with the peptide bonds to cause the color change.
