Chapter 4 & 5 - Carbon and the Molecular Diversity of Life & The Structure and Function of Large Biological Molecules Flashcards
study of carbon containing compounds
organic chemistry
the number of covalent bonds an atom can form
valence
organic molecules consisting of only carbon and hydrogen
hydrocarbons
compounds that have the same numbers of atoms of the same elements but different structures and properties
isomers
differ in the covalent arrangements of their atoms
structural isomers
carbons have covalent bonds to the same atoms, but these atoms differ in their spatial arrangements due to the inflexibility of double bonds
cis-trans isomers (geometric isomers)
isomers that are mirror images of each other and differ in shape due to the presence of an asymmetric carbon
enantiomers
carbon that is attached to four different atoms or groups of atoms
asymmetric carbon
chemical groups that are directly involved in chemical reactions
functional groups
–OH
hydroxyl group
C=O
carbonyl group
-COOH
carboxyl group
–NH2
amino group
–SH
sulfhydryl group
–OPO3 2-
Phosphate group
–CH3
methyl group
large carbohydrates, proteins, and nucleic acids
macromolecules
long molecule consisting of many similar or identical building blocks linked by covalent bonds
polymer
repeating units that serve as the building blocks of a polymer - are smaller molecules
monomers
specialized macromolecules that speed up chemical reactions
enzymes
a reaction in which two molecules are covalently bonded to each other with the loss of a water molecule
dehydration synthesis
process that is the reverse of dehydration synthesis
hydrolysis
carbohydrate that is called a single sugar – made of CH2O
monosaccharides
consists of two monosaccharides joined by a glycosidic linkage
disaccharide
a covalent bond formed between two monosaccharides by a dehydration reaction
glycosidic linkage
macromolecules, polymers with a few hundred to thousand monosaccharides joined by glycosidic linkages
polysaccharides
