Proteins continued

Question 1

Denatured

Answer 1

modifying a protein’s original nature, through temperature and pH. If a protein is introduced to a different temperature than normal, or a different pH: INTRAmolecular bonds might break or not form.

This will will have an effect on the protein’s three dimensional shape. Now, it doesn’t have its normal funciton.

Question 2

Amino group

Answer 2

Single nitrogen bonded to two hydrogens. Functional group.

Question 3

Alpha carbon

Answer 3

Carbon next to a functional gorup in an organic compound.

Question 4

Carboxyl group

Answer 4

COOH - functional group consiting of OH and an O attached to a carbon atom.

Question 5

Peptide bonds

Answer 5

linking amino acids together in proteins

Question 6

Amphiprotic

Answer 6

molecues able of donating and accepting protons.
Ex, phospolipid bilayer - polar head and non polar tails.

Question 7

Dipeptide

Answer 7

molecule of two amino acids joined by peptide bond

Question 8

Oligopeptide

Answer 8

few amino acids joined by peptide bonds.

Question 9

Conformation

Answer 9

Chainging one amino acid can change the proteins three dimensional shape and function - known as proteins conformation.
