Functional Groups Flashcards
Amino Family
Amines
Amino Formula
H \ N -- R / H
Amino Properties
Acts as a base - tends to attract a proton to form: H I H -- +N -- H I H Attracts protons, functions as a base
Carbonyl Family
Aldehydes & Keytones
Carbonyl Formula for Aldehydes
O // R -- C \ H
Carbonyl Aldehydes Properties
Aldehydes react with certain compounds to prdouce larger molecules to form
OH I R -- C -- H I R
Carbonyl formula for Keytones
R – C – R
II
O
Carboxyl Family
Carboxylic Acids
Carboxyl Formula
O // R -- C \ OH
Carboxyl Properties
Acts as an acid – tends to lose a proton in solution to form
Hydroxyl Family
Alcohols
Hydroxyl Formula
R – OH
Hydroxyl Properties
Highly polar, so makes compounds more soluble through hydrogen bonding with water; may also act as a weak acid and drop a proton
Phosphate Family
Organic Phosphates
Phosphate Formula
O II R - O -- P -- O - II O -
Phosphate properties
When several phosphates are linked together, breaking O-P bonds between them releases large amounts of energy.
Carries two negative charges
Sulfhydryl Family
Thiols
Sulfhydryl Formula
R – SH
Sulfhydryl Properties
When present in proteins, can form disulfide (S-S) bonds that contribute to protein structure
CHONPS
Carbon Hydrogen Oxygen Nitrogen Phosphate Sulfur
Electronegativity
