19.5 Protein Hydrolysis and Denaturation

denaturation effect

loss of normal function of a protein

factors that can cause protein denaturation: heavy metal ions

react with sulfur ions

denaturation of egg proteins occurs when

the interactions in the tertiary structure in albumin and other proteins are disrupted

denaturation of a protein occurs when

the interactions that stabalize secondary, tertiary, or quaternary structures are disrupted which destroys the shape and renders the protein biologically inactive

denaturation involves

the normal shape of a protein

denaturation does NOT affect what

the primary structure of the protein: no peptide bonds are broken

hydrolysis occurs in what

the stomach and small intestine when enzymes catalyze the hydrolysis of proteins to give amino acids

factors that can cause protein denaturation: heat

breaks H bonds, salt bridges, and hydrophobic interactions

hydrolysis does what

breaks up the primary structure by breaking covalent peptide bonds that link the amino acids

factors that can cause protein denaturation: acids and bases

change the charge on some R groups, disrupting salt linkes and breaking H bonds

denaturation of protein occurs when an egg is what

cooked

the disruption of bonds holding together the secondary, tertiary, and quarternary structures

denaturation

factors that can cause protein denaturation: organic compounds

disrupt hydrophobic interactions

peptide bonds are broken through

hydrolysis reactions

factors that can cause protein denaturation: agitation

whipping that stretches peptide chains until interactionsn break
