Function and monomers

Monomer: Monomers are single units that make up the polymer (which are proteins, lipids, carbohydrates, nucleic acids). 

• The monomer of proteins are AMINO ACIDS. A bunch of amino acids make up proteins. That is all a monomer is, a building block for a larger unit. 
• The monomer for lipids are hydrocarbons. 
• Monomers for carbohydrates such as starch and glycogen (polysaccharides) are single sugar units called monosaccharides. Monosaccharides are sugars such as glucose and fructose, polysaccharides are larger sugar molecules such as starch and glycogen. 
• Monomers for nucleic acids, such as DNA and RNA, are nucleotides. 

Functional group: Groups of atoms within a molecule that interacts n predictable ways with other molecules. 

• Functional groups for carbohydrates are hydroxides, and short hydrocarbons such as methyls and ethyls.
• Functional groups for nucleic acids are small sugar units, nitrogen bases, and phosphate groups.
• Functional groups for lipids are hydrocarbons, esters, carboxyls, hydroxol, and hydrocarbons. 
• Functional groups for proteins are amines, ammonias, carboxyls and 20 remainder groups, which you probably wont need to know.
