Optical Isomers Properties of Molecules
Background image of page 4
Isomers Isomers are molecules that have the same chemical formula but different arrangements of the atoms. Structural isomers differ in terms of how atoms are joined together. Optical isomers (Enantiomers) are mirror images of each other. Optical isomers can occur whenever a carbon has four different atoms or groups attached to it.

Unformatted text preview: improve the solubility of organic molecules. Organic compounds with hydroxyl groups are alcohols . Isomers with aldehyde versus ketone carbonyl groups have different properties. Carboxyl groups have tendencies to dissociate and become fully charged, and therefore can interact with water. Organic Functional Groups Properties of Molecules Organic Functional Groups Amino groups are polar because nitrogen is electronegative. In addition, an amino group can capture a hydrogen ion (H + ) from the solution to become ionic (basic). A phosphate group bonds to the carbon backbone via one of its oxygen atoms. Phosphate groups are polar and under physiological conditions carry two negative charges (as two protons have dissociated from the oxygen atoms). A sulfhydryl groups resembles a hydroxyl group in shape and polarity. Sulfhydryl groups participate in forming disulfide bridges to help stabilize the structure of proteins....
