Types of Biological Reactions

Tuesday, July 25, 17

Condensation Reaction

Also know as dehydration synthesis  Creates a covalent bond between two substancesinvolves the removal of H from one substance and  a hydroxyl (-OH) from another

Tuesday, July 25, 17

Condensation Reaction

H and OH form H2O absorbs energyanabolic reaction: construct larger molecules from smaller ones

Hydrolysis Reaction

Also know as decomposition water molecule breaks a covalent bond holding two molecules togetherprovides an H to one molecule and a hydroxyl to another

Hydrolysis Reaction

releases energycatabolic reaction: break larger molecules into smaller ones.

Other Biological Linkages

Tuesday, July 25, 17

Ether Linkage

Hydroxyl + Hydroxyl → ether linkage + water

-OH + -OH → -R-O-R- + H2O

*R represents a carbon side chain

Ester Linkage

Carboxyl + Hydroxyl → ester linkage + water

+ -OH → + H2O

Amide Linkage

Amine + Carboxyl → amide linkage + water

+ → + H2O

Disulfide Linkage

Sulfhydryl + Sulfhydryl → disulfide linkage

-SH + -SH → S-S + H2
