确定检查IS_IDENTITY和/或IN_PRIMARY_KEY的表字段？

I am trying to determine the table column which has been identified as (or part there of) the primary key for a given table name.

I have been playing around with the INFORMATION_SCHEMA and the data within it, but nothing seems to relate to these table columns.

Have also been browsing around this website:

but without much luck so far.

Anyone have any suggestions?
