Not Soluble

What does the non solubility of lipids tell you about them?

What is a saturated lipid?

When all the carbons are bonded once. (Full)

What is a unsaturated lipid?

When there are multiple bonds between the same molecules (double bonds). (Not Full)

What tends to be true about unsaturated lipids?

They are less orderly, missing elements, and they are usually liquids.

Nucleic Acid Monomer

What is a 5 Carbon Sugar?

Pentose sugar, Either ribose or deoxyribose

Why are the polymers of nucleic acids so important?

They tell the cell what to do, and are important for reproduction.

Protein Monomer

Amino Acid

Protein Polymer

Polypeptide

Protein Functions

• Controlling Rate of Chem Reactions(Enzymes) + Regulate Cell Processes

• Needed for Cell-Structure

• Cell Transport

• Helps Fight Disease

Protein (Foods Its Found In)

Meat, Fish, Eggs, Dairy, Nuts

Protein Elements

Carbon, Hydrogen, Oxygen, Nitrogen

What two things do every amino acid have?

An Amino Acid Group = NH2 A Carboxyl Group = COOH

What does the 'R' represent in a diagram?

It is a placeholder letter, like the variable x. Since all amino acids have different make-ups, this used for later reference.

What are the covalent bonds of two amino acids called?

Peptide Bonds

What changes the specific functions of an amino acid?

The order they are linked together.

How many levels are there to a proteins make-up?

3/4

Primary (Protein)

The amino acid sequence (amino acids)

Secondary (Protein)

How it folds/coils (a-helixes/b-sheets)

Tertiary (Protein)

The final 3D structure of the protein (polypeptide chains)

Quaternary (Protein)

Multiple coming together (complex of protein molecule)

What is the difference between a monomer and a polymer?

A monomer is a single atom, small molecule, or molecular fragment that, when bonded together with identical and similar types of monomers, form a larger, macromolecule known as a polymer.

Levels of Organization(Smallest to Largest)

Atoms, Molecules, Macromolecules, Cells, Tissues

Structural Characteristics of Lipids

A glycerol backbone, 2 fatty acid tails (hydrophobic) + phosphate grp (hydrophillic)

Structural Characteristics of Proteins

They contain variable group of a carboxyl group, a R(varient), and an amino group

Structural Characteristics of Nucleic Acids

Long chainlike molecules composed of a series of nearly identical building blocks called nucleotides.

Saturated vs Unsaturated Lipids

Saturated fatty acids have hydrocarbon chains connected by single bonds only. Unsaturated fatty acids have one or more double bonds.

Relationship between DNA and proteins

DNA, RNA, and protein are all closely related. DNA contains the information necessary for encoding proteins, although it does not produce proteins directly. RNA carries the information from the DNA and transforms that information into proteins that perform most cellular functions.

Starches/Carbohydrates

What does 'Benedict's' test for?

Sugar/Glucose

What does 'Biuret' test for?

Proteins

What does the term 'organic' mean? (In relation to what we are learning)

When it contains carbon

What is the name of a plant carbohydrate that is used for structure?

Cellulose

Which of the groups of organic compounds do not dissolve in water, and include fats, oils, and waxes?

Lipids (non-soluble)

Which of the 4 groups of organic compounds consist of a head and tails arrangement, and may be used for long-term energy storage?
