biological molecules Flashcards
monomers+polymers of molecules like carbs
what is a monomer
smaller molecules
what is a polymer
large molecules
amino acids are
monomers
protein is a ___ made out of _____
polymer, amino acids
glycerol and fatty acids are
monomers
lipids are made out of ___ and ___ and is a ___
glycerol and fatty acids, polymer
carbohydrate has what elements
oxygen, hydrogen and carbon
protein elements
nitrogen, hydrogen, carbon and oxygen
lipids have what elements
carbon, oxygen and hydrogen
what is a monosaccharide
a simple sugar e.g. glucose
what is a disaccharide
two monosaccharides join together, e.g. maltose is formed from two glucose molecules
polysaccharide is what
when lots of monosaccharides join together (starch, glycogen)
are polysaccharides soluble, and what are they used for
insoluble and therefore useful as storage molecules
lipids made of
one glycerol molecule chemically bonded to three fatty acid chains
proteins are formed from
long chains of amino acids
Amino acids can be arranged in any order, resulting in
hundreds of thousands of different proteins
he shape of a protein determines
its function
