UNT Biology 1710 Dewey EX2

Proteins Do the work of the cell
Protein Enzyme catalysts - Speed up chemical reactions
Most Enzymes are Proteins
Protein Defense - Antibodies, immune systems
Protein Transporting - Creating systems that allow organisms to move
Protein Support - Support Cell membrane
Protein Regulation - Controls or regulates systems in body or cell
Protein Storage - Store different Macro-Molecules, nutrients, water, etc
Protein Polymers -Composed of 1 or more long, unbranched chain
Chain - Polypeptide
Monomers - Amino Acids
Amino Acid Structures (5) 1. Central Carbon atom 2. Amino group 3. Carboxyl group 4. Single Hydrogen 5. Variable R group
Are R groups the same in Amino Acids? No. They vary from acid to acid.
Amino acids joined by: Dehydration synthesis
Peptide bond Amino acids joined by dehydration synthesis
Where do Amino Acids come from? -We get them in our diet - You can also biosynthesize most from other compounds in a complex array of metabolic pathways
PKU Phenylketonuria
Phenylketonuria - Rare genetic metabolic disorder - Patients lack enzyme necessary to metabolize the amino acid phenylalanine - Phen. accumulates and is converted to phenylpyruvate which causes brain damage, mental retardation, seizures
4 Levels of Structure for Proteins 1. Primary 2. Secondary 3. Tertiary 4. Quaternary
Protein Primary structure - sequence of Amino Acids
Protein Secondary Structure - Interaction of groups in the peptide backbone
Alpha Helix - no R-types participate in the structure - Hydrogen bonds keeping helix together
Beta Sheet Hydrogen bonds through the peptide backbone
Protein Tertiary Structure - Final folded shape of a globular protein
Quaternary structure - Only if you have a protein made of only 1 sub-unit - subunits in a protein with 2 or more polypeptide chains
Sub-units - arrangement of individual chains

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
