Molecules that consist mainly of carbon. Biological molecules that contain only hydrogen and carbon. They contain covalent bonds with significant energy.
|
|
What are all the functional groups?
|
Hydroxyl(OH), Carbonyl(CO), Carboxyl(COOH), Amino(NHH), Sulfhydryl(SH), Phosphate(POOO), Methyl(CHHH)
|
|
What are macromolecules? What builds them? What breaks them apart?
|
Long molecules usually made of polymers. Dehydration synthesis. Hydrolysis.
|
|
What are the different kinds of macromolecules?
|
Proteins, Nucleic Acids, Lipids, and Carbohydrates.
|
|
What are the functions of proteins?
|
Enzymes, Defense, Transport, Support, Motion, Regulation, and Storage.
|
|
Describe an amino acid's structure.
|
An amino group connected to a carbon connected to an R group, a hydrogen, and a carboxyl group.
|
|
What happens when a protein denatures?
|
It unfolds and loses functionality.
|
|
What bonds form between amino acids?
|
Peptide bonds.
|
|
What are the levels of protein structure?
|
Primary (Amino Acid Sequence), Secondary (Fold), Motif (Collection of Folds), Tertiary (Final Folded Shape), Domains (Function Parts of the Tertiary), Quatemary (Group of Proteins that Function as a Unit)
|
|
What are chaperone proteins?
|
Proteins that assist in the folding of proteins as they are being assembled.
|
|
What are the types of nucleic acids? What are the parts?
|
DNA (store code for protein synthesis) and RNA (copied from DNA to form protein). A phosphate, a 5 carbon sugar, and a nitrogeneous base.
|
|
What is the loose definition of lipids?
|
Molecules insoluble in water.
|
|
What are fats? What are saturated fats? Unsaturated?
|
A glycerol with 3 fatty acid chains. Fats with only single bonds between carbons (usually solid). Fats with one or more double bonds (usually liquid).
|
|
What are phospholipids?
|
Lipids with a glycerol, 2 fatty acid chains, and a phosphate group. They form all biological membranes.
|
|
What are isomers?
|
Compounds with the same molecular formula but different molecular structure.
|
|
What are carbohydrates?
|
Loosely, they are molecules with carbon, hydrogen, and oxygen in a 1:2:1 ratio.
|
|
What is a monosaccharide? A disaccharide? A polysaccharide?
|
A simple sugar. Two simple sugars joined. A string of sugars (called a starch when formed by plants).
|
|
Humans transport glucose as a ___________, plants as a ___________.
|
Monosaccharide, Disaccharide.
|
|
What is the sugar produced by plants to make wood? What is the sugar produced by arthropods and fungi to make carapace? How are they similar?
|
