proteins

Question 1

bonds in primary protein structure

Answer 1

peptide

Question 2

primary protein structure

Answer 2

sequence of amino acids in polypeptide chain bonded by peptide bonds

Question 3

bonds in secondary protein structure

Answer 3

hydrogen bonds (between amino and carboxyl groups)

Question 4

secondary structure of a protein

Answer 4

protein folding due to hydrogen bonds causing alpha helix and beta pleated sheets (antiparallel strands)

Question 5

tertiary protein structure bonding

Answer 5

hydrogen ionic, disulphide

Question 6

tertiary protein structure

Answer 6

3d arrangement of polypeptide chains (which effects proterties and structures like active sites) due to bonds in the R group (hydrogen, ionic disulphide)

Question 7

quaternary protein structure

Answer 7

arrangement of proteins together (globular)

Question 8

is haemoglobin globular of fibrous

Answer 8

globular

Question 9

is collagen globular or fibrous

Answer 9

fibrous

Question 10

fibrous structure

Answer 10

no tertiary
long straight polypeptide chains
strong due to structural role
insoluble
hydrophobic on outside
repeated amino acid sequence
cross linking between polypeptide chains

Question 11

globular structure

Answer 11

hydrophilic on outside due to polar amino side chain
quaternary structure
hormones or enzymes
little repetition in amino acid sequence

Question 12

How many amino acid R groups are there

Answer 12

20
