GrubHub Inc. made a big splash in its trading debut Friday, but next week may test the size of investor appetites for initial public offerings. It’s a busy week with 15 companies expected to emerge. Here’s a glance at the companies scheduled to go public:

Adamas Pharmaceuticals Inc. – The Emeryville, Calif.-based brain drug developer creates products for central nervous system disorders such as Parkinson’s and Alzheimer’s. It is one of several drug makers to go public this year. The company has a deal with Forest Laboratories for co-creation of a dementia drug, which is pending FDA approval.

Aldeyra Therapeutics Inc. -The biotechnology company, based in Burlington, Mass., develops drugs designed to trap aldehydes, which can be toxic at high levels and have been linked to some diseases. The company creates treatments for rare skin and eye conditions.

Ally Financial Inc. – The finance company’s offering could make taxpayers whole for a $17.2 billion government bailout during the financial crisis. Ally, known as GMAC Inc. at the time of its bailout, had been the auto lending arm for General Motors. It was nearly wrecked by bad subprime mortgages made by its Residential Capital unit. It has since cut ties to ResCap and transformed itself into a company focused on U.S. auto lending and banking.

Farmland Partners Inc. – Another real estate investment trust expected to go public next week. The Westminster, Colo.-based company owns farmland properties in North America. Real estate investment trusts receive special tax consideration. They can be a popular business model with investors because they return the bulk of their profits to shareholders.

It also has a pipeline of 175 franchise hotels planned for openings in North America, Colombia and Honduras.
