The four general types of biological molecules are ___carbohydrates___,
____lipids______, __proteins__________, and ___nucleic acids_.

Biomolecules are synthesized by the process of _dehydration___
__synthesis_____ and broken apart by the process of _hydrolysis_____.

Carbohydrates are composed of _C_, _H_, and _O_. Carbohydrates are soluble in water,
so carbohydrates are _hydrophilic____.
       One sugar molecule is called a _monosaccharide____.
       Two sugar molecules linked by a covalent bond is called a _disaccharide_.
       More than two sugar molecules linked by covalent bonds are called
       _polysaccharide___.

All lipids are insoluble in water, so lipids are called _hydrophobic___. The three classes
of lipids are _fats/oils____, _phospholipids_________, and __steriods_________.

A protein is composed of monomers termed _amino acids___. Each of these monomers
are composed of 4 parts: _amino group_______, _carboxyl group___________,
_variable group or side chain_ and _hydrogen atom______.

Nucleic acids are composed of monomers termed _nucleotides______. Each monomer
has 3 parts: _5 carbon sugar___, _phosphate group__, and _nitrogenous base___.
         1.   Classify the biological molecule into one of the four major divisions.
         2.   If the molecule is a carbohydrate or lipid, provide the sub-classification of the molecule.
         3.   Circle and identify all functional groups in each molecule.
         4.   If the molecule is a protein, identify all the peptide bonds that are present.
