Organic Chemistry Flashcards
What is the backbone of all Organic Chemistry called
Carbon Skeleton
What are the 4 major categories of organic macromolecules
1) Carbohydrates
2) Lipids
3) Proteins
4) Nucleic Acids
What are the 4 main elements in organic molecules/compounds
Carbon
Hydrogen
Oxygen
Nitrogen
What type of bonds hold organic compounds together
Covalent (mainly)
Hydrogen (sometimes)
What shape does Glucose form
Hexagon
What are the carbons in the skeleton that bind to hydrogen called
Hydrocarbons
What are the 7 main Functional Groups
1) Hydroxyl
2) Sulfhydryl
3) Carbonyl
4) Carboxyl
5) Ester
6) Phosphate
7) Amino
Characteristics of Hydroxyl Group
Contains OH
Polar/Hydrophilic
Ex Alcohol
Characteristics of Sulfhydryl Group
Contains SH group
Characteristics of Carbonyl Group
Keytones and Aldehydes
Characteristics of Carboxyl Group
Contains COOH
Component of Amino Acids
Can act as an acid
Characteristics of Ester Group
Compounds found in fats, oils and triglycerides
Characteristics of Phosphate Group
Contains PO4
Key component of ATP
Characteristics of Amino Group
Contains NH2
Component of Amino Acids
Can act as a base (NH3)
What does the “R” signify
Variable group
What the Functional Group is attached to
Define Monomer
Smallest unit of an organic molecule
Ex Glucose
Define Polymer
Larger organic molecule consisting of monomers
*Usually created by dehydration synthesis
Ex Glycogen
Define Isomer
Molecules with same chemical formula but different chemical structure
*Functional group is attached to different Carbon #s
Example of an Isomer
Glucose and Fructose
*Reversible Reaction
How does a Dehydration reaction effect Peptide Bonds
Removes water to form peptide bonds
Ex Glucose + Fructose = Sucrose + H2O
How does a Hydrolysis reaction effect Peptide Bonds
Add water to break peptide bonds
Ex Sucrose + H2O = Glucose + Fructose
Which Elements make up Carbohydrates
Carbon
Oxygen
Hydrogen
Define Carbohydrate
Carbon molecules that are saturated with Hydrogen and Oxygen
*Watered /Hydrated Carbons!
What suffix do most carbohydrates end with
“Ose”
What are the 3 Classifications of Carbohydrates
Monosaccharides
Disaccharides
Polysaccharides
What is the monomer of Charbohydrates
Monosaccharides
Examples of Monosaccharides
Glucose, Fructose, Gelactose, Ribose, Deoxyribose
What is a Disaccharide
Product of 2 or more monosaccharides by dehydration synthesis
Ex Glucose + Fructose = Sucrose (disaccharide) + H2O
What is a polysaccharide
Up to thousands of monosaccharides combined together
3 Examples of Polysaccharides
Glycogen
Starches
Cellulose
What is Glycogenolysis
Breakdown of Glycogen into Glucose
What is Glycolysis
Breakdown of Glucose into smaller components to make ATP
What is Glycogenesis
The making of Glycogen from Glucose
What percentage of our body is made up of Carbohydrates
Less than 3%
Characteristics of Lipids
Less oxygen to hydrogen ratio
More non-polar/hydrophobic
Do not dissolve easily in water
What lipids will dissolve in Water (3)
Very small ones
Glyco-lipids (sugar-fats)
Lipo-proteins (fat-proteins)
What are the 6 Classifications of Lipids
1) Fatty Acids
2) Triglycerides
3) Phospholipds
4) Steroids
5) Eicosanoids
6) Other
What are Fatty Acids
Simplest lipid (not a monomer) Consist of a Carboxyl group and a Hydrocarbon Chain
What is a Saturated Fatty Acid
All Carbons on the chain are fully saturated with Hydrogen
*Single covalent bonds only
What is an Unsaturated Fatty Acid
A fatty acid with 1 or more double covalent bonds
What is a Monounsaturated Fatty Acid
Fatty acid with 1 double covalent bond (1 kink)
What is a Polyunsaturated Fatty Acid
Fatty acid with 2 or more double covalent bonds (2+ kinks)
What are Triglycerides
Contain 1 Glycerol molecule and 3 Fatty Acids chains
aka Triglycerols
Formed by Dehydration Synthesis
*Unlimited ability to be stored in adipose tissue in certain areas of the body
Difference between Oils and Fats
Fats: tend to be Saturated Fats - solid at room temperature
Oils: tend to be Unsaturated Fats - liquid at room temp
What type of fats are better for us and why
Polyunsaturated Fats
More Covalent Bonds = Less Hydrogen = easier for body to metabolize and incorporate into our tissues
