- 1What are maltose, sucrose and lactose made up of?Maltose = two glucose.
Sucrose = glucose + fructose (1-2)
Lactose= galactose and glucose (1-4) - 2What does tRNA do?Carries amino acids and allows ribosomes to synthesise peptide chains.
- 3Three reasons why no other different base pairing can occur?Pyrimidines are too small to enable complementary strands to form double helix. Cannot form enough hydrogen bonds for stable interactions. Purines are too bulky.
- 4Major and minor grooves face?Distance between the end of the bases of DNA
- 5Phosphodiester bondsJoining nucleotides together in the RNA and DNA chains.
- 6Difference between DNA and RNA?RNA has a -OH group on the 2nd carbon below the ring and DNA has a -H group on the 2nd carbon below the chain.
- 7NucleosidesDon't not contain the phosphate in nucleotides.
- 8GlycerophospholipidsElements of the cell membrane, contains phosphodiester and amino alcohol.
- 9AnandamideIs a fatty acid amide, in the brain it interacts with the canabinoid receptor and plays a role in making and breaking short term neural connections.
- 10Why can't humans metabolise cellulose?Humans do not possess enzymes capable of dealing with beta-linkages.
- 11Alpha amino acidsAmino group is joined to the 1st carbon next to the -COOH group.
- 12Propensity of an amino acidIs its tendency to appear in a secondary structure type.
- 13Pattern of hydrogen bonding in a alpha helix amino acid is?NH1 to CO2
- 14Tertiary structure of proteinsOverall 3-D shape of the protein
- 15Secondary structure of proteinsThe types of ordered structures taken up by the protein chain such as the alpha helix and the beta sheets.
- 16Primary structure of proteinsOrder of the amino acids in the peptide sequence.
- 17Hydrogen bond which stabilises peptide secondary structures.O in C=O is negatively charged and the H in N-H is positively charged.
- 18Peptide bondH - N - C = O
- 19Isoelectric pointThe point the amino acid is completely balanced between the anionic and cationic forms and is primarily in the neutral or zwitterionic form.
- 20ZwitterionDipolar ion which is produced by intramolecular acid/base reactions.
