1
Synthetic polymers
________ are ones made in a factory, for example nylon, terylene and lycra.
New cards
2
Terylene
________ is a polyester made from dicarboxylic acid monomers (a carboxylic with a- COOH group at either end) and diols (an alcohol with an- OH group at either end)
New cards
3
Simple sugars
________ can be fermented to produce alcohol.
New cards
4
Nylon
________ is a polyamide made from dicarboxylic acid monomers (a carboxylic with a- COOH group at either end) and diamines (an amine with an- NH2 group at either end)
New cards
5
water molecule
A(n) ________ is eliminated due to it being a condensation reaction.
New cards
6
Proteins
________ are the building blocks of cells and are essential for growth.
New cards
7
Polymers
________ are large molecules built by linking 50 or more smaller molecules called monomers.
New cards
8
incomplete combustion
If incinerated by ________, carbon monoxidewill be produced which is a toxic gas that reduces the capacity of the blood to carry oxygen.
New cards
9
Hydrolysis
________ is the splitting up of a molecule using water.
New cards
10
Complex carbohydrates
________ are called polysaccharides.
New cards
11
Yeast
________ contains a naturally occurring enzyme, zymase (a biological catalyst) that breaks down starch or sugar to glucose.
New cards
12
Chromatography
________ is carried out in much the same way, the only difference being that it is not obvious on the resulting chromatogram where the amino acids and sugars are located as they are colourless.
New cards
13
Simple carbohydrates
________ are called monosaccharides and are sugars.
New cards
14
Polyethene
________ is formed by the addition polymerisation of ethene monomers.
New cards
15
Biological catalysts
________ also consist of protein.
New cards
16
Carbohydrates
________ provide energy which is released during cellular respiration.
New cards
17
small subscript n
A(n) ________ is written on the bottom right hand side to indicate a large number of repeat units.
New cards
18
chromatogram
The ________ is dried and sprayed with a locating agent to enable the substances to be seen.
New cards
19
Repeat units
________ are used when displaying the formula.
New cards
20
Condensation polymerisation
________ forms the polymer molecule and one water molecule per linkage.
New cards
21
Condensation polymers
________ are formed when two different monomers are linked together with the removal of a small molecule, usually water.
New cards
22
amide linkage
A(n) ________ is formed with the subsequent loss of one water molecule per link.
New cards
23
colourless compounds
Originally used for separating coloured substances, chromatography can also be used to identify ________, such as amino acids and simple sugars, using locating agents.
New cards
24
ester linkage
A(n) ________ is formed with the subsequent loss of onewater molecule per link.
New cards
25
Amino acids
________ are small molecules containing NH2 and COOH functional groups.
New cards
26
Addition polymers
________ are formed by the joining up of many monomers and only occurs in monomers that contain C= C bonds.
New cards
27
twenty common amino acids
There are ________, each differing by their side chain, represented by R.
New cards
28
hydrolysis of carbohydrates
The identification of the products of the ________ and proteins can be done using chromatography.
New cards
29
Nylon
________ is a polyamide used to produce clothing, fabrics, nets and ropes.
New cards
30
complex carbohydrates
The ________ also undergo hydrolysis (water is used to split up the molecule) and produce the simple sugar monomers from which they were made.
New cards
31
Polymers
________ release a lot of heat energy when incineratedand produce carbon dioxide which is a greenhouse gas that contributes to climate change.
New cards
32
Terylene
________ is used extensively in the textile industry and is often mixed with cotton to produce clothing.
New cards
33
yeast
The ________ respires anaerobically using the glucose to form ethanol and carbon dioxide:
New cards
34
Proteins
________ can therefore be hydrolysed and will produce the monomer they were formed from, amino acids.
New cards
35
Carbohydrates
________ are compounds of carbon, hydrogen and oxygen.
New cards
36
simple carbohydrates
There are ________ and complexcarbohydrates.
New cards
37
condensation polymers
They are ________ formed from simple sugar monomers.
New cards
38
Terylene
________ is a polyester made from monomers which are joined together by ester links.
New cards
39
Proteins
________ are condensation polymers which are formed from amino acid monomers joined together by amide links (in ________ also known as a peptide link) similar to the structure in nylon.
New cards
40
Polymers
________ can be recycled but different polymers must be separated from each other which is a difficult and expensive process.
New cards
41
Proteins
________ can contain between 60 and 600 of these amino acids in different orders.
New cards
42
The name of the polymer is deduced by putting the name of the monomer in brackets and adding poly
as the prefix
New cards
43
The linkage formed within the polymer is an -O
linkage called a glycosidic linkage
