How are amino acids linked and what do they form?
|
Amino Acids build proteins by connecting the carboxyl grp of on amino acid w/ the amino grp of the next amino acid.
|
|
|
How are polysaccarides built and what is their monomer form?
|
polysaccharides are built by linking the first carbon of one sugar with the 4th carbon of the next sugar.
|
|

|
What does more product then reactant mean?
What does a large Ka mean? |
Strong acid; strong acid measurment of amt of hydrogen ions released in water
|
|
|
Define pKa
|
-logKa; measures acid strenght with the smaller the value the stronger the acid.
