lab 4 Flashcards
molecules that contain two or more carbon atoms bonded together
organic molecules
atoms share a pair of electrons and can be classified as either polar or non polar
covalent
pair of electrons NOT shared equally
polar
pair of electrons shared equally
non polar
dische diphenylamine
reagent that tests specifically for the presence of deoxyribose sugar found in DNA
has three different parts: a sugar, a phosphate group, and a nitrogenous base
nucleotide
can be used to test for the presence of peptide bonds found in proteins
biuret reagent
when a proteins structure is destroyed
denatured
amino acids held together by covalent bonds
peptide bonds
building blocks or monomers that make up all proteins
amino acids
gain of electron
reduction
loss of electron
oxidation
monosaccarides or disaccharides that contain a free aldehyde or ketone group
reducing sugars
used to test for reducing sugars
Benedict’s reagent
formed when 3 or more monosaccharides are covalently bonded together
