Proteins

Question 1

Proteins

Answer 1

polymers of amino acids;

Question 2

Amino Acid

Answer 2

a molecule that contains an Amine (N) and a Carboxylic Acid (COOH); the alpha carbon is chiral with a side chain determining the type of amino acid;

Question 3

Alpha Carbon

Answer 3

the carbon in an amino acid linking the amine and the carboxylic acid;

Question 4

Polar Amino Acid

Answer 4

amino acid with a side chain containing a polar covalent bond;

Question 5

Non-Polar Amino Acid

Answer 5

amino acid with a side chain without a polar covalent bond;

Question 6

Acidic Amino Acid

Answer 6

amino acid with a side chain with a carboxylic acid

Question 7

Basic Amino Acid

Answer 7

amino acid with a side chain with an amine;

Question 8

Neutral Amino Acid

Answer 8

amino acid without an amine or carboxylic acid;

Question 9

Amino Acid Polymer

Answer 9

Protein

Question 10

Linking Bond Between Amino Acids

Answer 10

peptide bond;

Question 11

Long Peptids

Answer 11

pepteins; polypeptides;

Question 12

4 Types of Protein Structure

Answer 12

primary structure (1st degree); secondary structure (2nd degree); tertiary structure (3rd degree); quatinary (4th degree);

Question 13

Primary Structure

Answer 13

sequence of amino acids;

Question 14

Secondary Structure

Answer 14

local or short range or twisting of protein chain; including: alpha helix, beta pleated sheets, other;

Question 15

Tertiary Structure

Answer 15

long range or overall folding of the protein chain; unfolded, partially forded, or completely folded; folds held in place by disulfide bonds (-S-S-):

Question 16

Quatinary Structure

Answer 16

number of peptide chains;

Question 17

Fiberous Proteins

Answer 17

do not disolve in water; tertiary (3rd degree) structure is unfolded, straight, or linear; single type of secondary structure throughout the chain;

Question 18

Globular Proteins

Answer 18

disolve in water; tertiary (3rd degree) structure is folded, ball, or glob; hydrophilic (polar) anions are on the outside;

Question 19

Denaturation

Answer 19

the process of disrupting protein structure; seperated chains (loss of quatinary structure); protein structure can unfold (loss of tertiary structure); alpha helix and beta pleated sheet can change (loss of secondary structure); primary structure remains unchanged;
