## What is Impari Amino?

Memorize the amino acids for biology and biochemistry with this highly customizable quizzing application.  Adjust it to suit your particular learning requirements.

Draw questions from one or more of the six choices:
   * amino acid full names
   * one letter symbols
   * three letter symbols
   * chemistry structural formulas
   * chemistry linear formulas
   * mRNA codons

Select answers from one or more of the nine choices:
   * amino acid full names
   * one letter symbols
   * three letter symbols
   * chemistry structural formulas
   * chemistry linear formulas
   * mRNA codons
   * side chain properties
   * protein secondary structure bias
   * nutritional essentiality

Select the question pool to include three different types of questions:
   * single answer selection
   * multiple choice selection (choose all)
   * type the answer questions

Configure the number of questions and how they are selected:
   * user set number of random questions (allowing repeats)
   * user set number of unique, non-repeating questions
   * ask ALL questions currently matching the selection filters

Configure how missed answers are handled with multiple options:
   * just continue with quiz
   * repeat missed questions one time
   * keep repeating missed questions until answered correctly

Utilize filters to further limit the questions included and target your individual learning goals.

Save settings that meet your needs to be used automatically with future use of the application - or reset to the system defaults at will.

All of this allows you to configure the app to help you quickly learn the amino acid properties, chemical names, abbreviations, and chemical structures.  It is an ideal study aid for biology and biochemistry students who need to memorize various portions of this information.
