Monomers, polymers and monosacharide's

What is a monomer

* smaller unit
* simple molecule
* join together to form polymers

What is a polymer

* large molecule
* complex
* composed of long chains of monomers

What monomers form lipids

Fatty acids and glycerol

What polymer do fatty acids and glycerol form

lipids

What monomer forms amino acids

amino acids

What polymer do amino acids form

protein

What monomer makes up DNA

Nucleotides

What polymer do nucleotides form

DNA

what is a condensation reaction

where a chemical bond is formed and a small molecule of water is released

How can biological molecules be split into monomers

hydrolysis reactions

what do hydrolysis reactions do

break a chemical bond by the addition of a water molecule

What are monosaccharides

sweet tasting, soluble substances with the general formula (CH₂O)ₙ, the letter n can be any number 3 to 7

What is the main monosaccharide group we look at

hexoses or C₆H₁₂O₆, this is the chemical formula for glucose, fructose and galactose
