Answer 29

peptide bonds to form Polypeptide chains

Answer 30

alpha helix

Answer 31

beta sheets

Answer 32

disulfide bonds

Answer 33

Polypeptide chains that fold into regular structures such as alpha helix, and beta sheet

Answer 34

Hemoglobin

Answer 35

Chains of amino acids in a specific sequence

Answer 36

Coiled structures stabilized by intracain hydrogen bonds

Answer 37

Stabilized by hydrogen bonds between polypeptide strands

Answer 38

Not as rod like, fully extended not tightly coiled

Answer 39

Defect in collagen, Brittle bone disease occurs if a mutation results in the substitution of another amino acid in place of glycine

Answer 40

lack of vitamin C preventing hydroxylation of collagen leading to abnormalities in collagen

Answer 41

absence of vitamin K leading to proteins not being carboxylated

Answer 42

Refers to spatial arrangement of amino acids that are far apart in the primary structure and to the pattern of disulfide bond formation

Answer 43

Can be as simple as two identical polypeptide chains or as complex as dozens of different polypeptide chains

Answer 44

Three-dimensional structure formed by hydrogen bonds between peptide NH and CO groups of amino acids that near one another in the primary structure

Answer 45

binds oxygen

Answer 46

Hemoglobin

Answer 47

Globular proteins

Answer 48

Spatial arrangement of subunits and their nature of their interaction

Answer 49

Spatial arrangement of amino acids that are far apart in the primary structure

Answer 50

Structure assemble with other chains to form arrays such as the complex of six insulin molecules

Answer 51

Denaturants

Answer 52

Lack of vitamin D which prevents hydroxylation of collagen

Answer 53

Lack of vitamin C which prevents hydroxylation of collagen leading to abnormalities in collagen

Answer 54

due to absence of vitamin K leading to clotting proteins not being carboxylated
