what are the monomers of proteins called
amino acids
what are the two functional groups of an amino acid
- amine group (NH2)
- carboxylic acid group (COOH)
what are the two functional groups of an amino acid joined by
a carbon
what is there also in an amino acid and what does this determine
‘R’-changes on what amino acid it is
why do we call amino acids amino acids
as they contain an amino group, and a carboxylic acid
these two functional groups allow adjacent amino acids to join together through…
- condensation reactions
what is taken from the amine group to make water in condensation polymerisation
H
what is taken from the acid group to make water in condensation polymerisation
OH
what does the loss of the OH from the acid and H from the amine mean that what could bond
carbon and nitrogen to bond (called amide bond)
reaction for condensation polymerisation of amino acids
variety of amino acid monomers → protein polymers + water
what are polysaccharides made of
carbon oxygen and hydrogen
what are polysaccharides
carbohydrates joined together
names of the monomers and polymers of carbohydrates
- monomers= glucose and fructose
- polymers= starch and cellulose
cellulose: how its different to starch
- this is because its packed more closely
- glucose molecules form long, straight chains
- these long chains of glucose molecules lie parallel to each other and are linked by stronger intermolecular forces with neighbouring chains
