type of chemical bond that occurs when H bonds with N,O,F; cause of many physical properties
molecules with same atoms but with different spatial orientations of functional groups
sedative containing mix of D and L-stereoisomers; causes severe birth defects; now used to treat AIDS, leprosy, cachexia
a double sugar consisting of two monosaccharides linked together via condensation reaction (e.g. sucrose = glucose+fructose)
many monosaccharides linked together via condensation reactions; starch and glycogen are examples
