Ester Linkage |
Bond between a fatty acid and glycerol |
|
|
Triglyceride |
Three fatty acids joined to glycerol |
|
|
Phospholipid |
Glycerol joined to two fatty acids and a phosphate group. Have a hydrophilic head and hydrophobic tail. Major component in cell membranes. |
|
|
Steroids |
Lipids characterized by a carbon skeleton consisting of four rings with functional groups attached. Example: cholesterol |
|
|
Peptide bonds |
Link amino acids to form proteins |
|
|
R group |
Unique group on an amino acid that makes it behave differently. Can be polar, nonpolar, charged, or neutral. |
|
|
Primary structure |
The unique sequence of amino acids in a long chain |
|
|
Secondary structure |
The primary structure begins to fold due to hydrogen bonding at regular intervals along the polypeptide backbone. Two types are alpha helix and pleated sheet. |
|
|
Tertiary structure |
Irregular contortions of a protein molecule due to interactions of side chains. The stage when a protein becomes functional. |
|
|
Quaternary structure |
The association between two or more tertiary structures |
|
|
Nucleotides |
Monomers that make up nucleic acids. Composed of 1) a nitrogen base 2) a phosphate group and 3) a pentose sugar (deoxyribose or ribose) |
