Hipposudoric acid is a complex molecule that contains multiple functional groups, including hydroxyl groups. However, the exact location and structure of these hydroxyl groups in hipposudoric acid is currently unknown.

This is because the complete structure of hipposudoric acid has not been fully elucidated yet. While scientists have been able to identify some of its components and properties, the exact arrangement of atoms within the molecule remains a mystery.

Therefore, it is not possible to definitively answer your question at this time.

It's important to note that:

* Hipposudoric acid is a unique molecule found in the sweat of hippos.

* It is responsible for the red-orange color of hippo sweat.

* The molecule is thought to be a mixture of complex compounds.

Research into the exact structure of hipposudoric acid continues, and hopefully, we will have a complete understanding of its structure, including the location of its hydroxyl groups, in the future.
