Proteins/Amino acids Structure

Question 1

Protein

Answer 1

A polymer consisting of monomer amino acids

Question 2

A chain of amino acids is also called

Answer 2

a polipeptide

Question 3

Covalent bonds that join amino acids are also called

Answer 3

peptide bonds

Question 4

Amino acid structure (MUST KNOW VERY WELL)

Answer 4

Question 5

Amino acids have 3 components. What are these? ESSAY QUESTION

Answer 5

1) amino group (-NH2)
2)Carboxyl group (-COOH)
3) R group/side chain (different for each amino acid)

Question 6

the process by which 2 amino acids join together, where water is lost and a peptide bond forms is called

Answer 6

dehydration synthesis

Question 7

Which 2 atoms join when 2 amino acids create a peptide bond?

Answer 7

C and N

Question 8

The primary structure of a protein

Answer 8

describes the sequence of amino acids

Question 9

Secondary structure

Answer 9

(1) describes the shape of the protein as a result of hydrogen bonding between amino acids

(2) Two basic shapes: alpha helix or beta pleated

Question 10

Tertiary structure

Answer 10

• Describes the complete 3D folding pattern of the protein
• Som parts are straight, some have alpha helix folding, some parts beta pleating

Question 11

Quarternary structure

Answer 11

Multiple tertiary structures combined

(figure shows 2 alpha and 2 beta structures)
