--- Quote from: Kimo Jesus on June 06, 2010, 10:01:52 am ---look proteins ( polyamide ) + carbs ( polysacharide , starch ) , if u want to get the monomers ( repeating units ) , we use acid hydrolysis ( heat under refulux with dil. aq HCL )
for protien we get amino acids , for carbs we get monosacharide
but for fats , to get the monemers i.e carboxylic adn the glycers we use Alkalne hydrolsis then acid hydrolisis ( the opposite to the above^)
Si?

are we required to know the molecular structures of fats, glycerol, fatty acids , soap compounds? how about the symbol formula (molecular)?
