AminoAcidQA is an App containing about eighty revision questions and answers on amino acid metabolism. It is hoped that it will help University students revise amino acid metabolism at home or on the go. It is not an exhaustive treatment of amino acid metabolism. However, it is hoped that it will enable you to test your knowledge of key facts in amino acid metabolism.

Topics include:-
Amino acids.
Enzymes involved in protein digestion.
Enzymes involved in amino acid formation and degradation.
Examples of medical conditions resulting from deficiencies of enzymes involved in amino acid metabolism.
Essential and non-essential amino acids.
The urea cycle.
Glucogenic and ketogenic amino acids.
Amino acids used to make biomolecules other than proteins

EnzymeQA is an App containing about 130 revision questions and answers on enzymology. It is restricted to considering single substrate catalysis. It is hoped that it will help University undergraduate and postgraduate students revise enzymology at home or on the go. It is not an exhaustive treatment of enzymology. However, it is hoped that it will enable you to test your knowledge of key facts in enzymology.



For those of you planning to determine kcat, kcat/Km and Km, EnzymeQA should help you check that you have the appropriate experimental conditions for determining catalytic constants. Likewise it should help planning to determine Ki values for competitive inhibition.



If you have Michaelis-Menten data to analyze you might be interested in the Mac program MMfit which is in the Mac App store.



Topics in EnzymeQA include:-

Michaelis Menten equation.

Initial rate measurements.

Setting the appropriate concentrations of enzyme and substrate for determining catalytic parameters.

Defining Vm, kcat, Km, kcat/Km, Ki and IC50 values.

Units of catalytic constants.

Order in enzyme and substrate at various substrate concentrations.

Methods for determining catalytic constants.

Experimental conditions for measuring catalytic constants.
Competitive inhibition.

Determining Ki values for competitive inhibition.
Relationship between Ki and IC50 values.

Brief mention of noncompetitive, mixed and uncompetitive inhibition.

pH dependence of catalytic constants.

Activities and Specific Activities.

Determining kcat/Km by complete hydrolysis of substrates.
pH and pH values
Analysis of pH data
log plots
Elisa
Enzyme cycling
Transition state analogues
Catalytic antibodies
Ribozymes

NMRQA is an App containing about a hundred and thirty simple revision questions and answers on NMR. This App is not intended for people who are not familiar with the basic concepts of NMR. Obviously it is not intended for NMR experts. It is intended for scientists and research students who are using NMR and want to check their knowledge of basic NMR facts, experimental parameters, signal processing, relaxation and methods of obtaining maximal signal-to-noise.NMRQA may also be useful for undergraduates undertaking advanced courses on 1D-NMR. It only gives short single or two sentence answers and so it is not intended to replace textbooks or user manuals but it may help you understand them. If you want to analyze pH dependent changes in chemical shift you may find the program "ppmfit" in the Mac app store useful. If you want to estimate the contributions of dipolar relaxation and relaxation by Chemical Shift Anisotropy(CSA) to carbon-13 T1 values you should find "T1calc" in the Mac app store useful.

It does not contain the material covered in most undergraduate lecture courses or elementary texts and it is limited to 1D NMR. Its focus is on practical aspects. It is hoped it will help you interact with NMR operators and set up your own NMR experiments. There is a list of the topics covered below.


Topics include:-
Larmour frequency and NMR operating frequency.
Chemical shift.
Gyromagnetic ratio.
Locking and shimming.
Sensitivity and natural abundance 1H,13C,15N, 19F and 31P.
Pulse widths.
Paramagnetic effects on signals.
T2 relaxation and optimum acquisition time.
Zero filling.
Signal-to-noise.
Folding and truncation.
Exponential multiplication and linebroadening.
T1 relaxation.
Ernst equation.
Optimising pulse rate and pulse angles.
Measuring T1 values using the progressive saturation technique.
Measuring T1 values using the inversion recovery technique.
Dummy scans.
Dipolar and CSA relaxation.
Effect of molecular size on dipolar and CSA relaxation.
Effect of magnetic field strength on dipolar and CSA relaxation.
Solid State NMR
Magic angle spinning
Cross polarisation
CPMAS
Dynamic Nuclear Polarisation (DNP) in solid state NMR
Temperature jump DNP.
