8 of 38
why are lipids not a polymer?
they are not a polymer as they are made of more than one polymer
9 of 38
what is a convalent bond?
when atoms share electrons
10 of 38
what type of reaction joins monomers together?
condensation reaction
11 of 38
what is removed during condensation reaction?
water
12 of 38
why is carbon a key elemnt is biological molecules?
it binds strongly to other carbon elemants 2. binds to four convalent bonds which allows large molecule to be made 3. can make branched chains and rings 4. carbon can from double bonds with either another carbon or oxygen atom
13 of 38
what ae the two things that always form from a concensation reaction
1. convalent bond 2. large molecule from small molecules
14 of 38
what reaction breakes down a polymer into a monomer
hydrolysis
15 of 38
what is need for hydrolysis to work?
water to be added
16 of 38
what makes a metablic?
anabolic + catabolic = metabolic
17 of 38
whats an anabolic reaction?
small molecules join
18 of 38
whats a catabolic reaction?
large molecules are broken down.
19 of 38
on carbon 1 what way is the OH on in alpha glucose?
top
20 of 38
what is the differencce between alpha and beta glucose?
ucose the Oh is on the bottom of the carbon 1 whereas on beta glucose it is on the top
21 of 38
what is an isomer?
molecule which has the same formular but a different structure
22 of 38
if there are differences like structure what does it affect?
affects the tasts, digestibility and polymer found
