Threonine is one of the 20 standard amino acids used in the biosynthesis of proteins. The R group in threonine, also known as the side chain, contains two functional groups.

1. Hydroxyl Group (-OH): This is the functional group that makes threonine a polar, uncharged amino acid. The presence of the hydroxyl group allows threonine to form hydrogen bonds with water, making it hydrophilic.

2. Methyl Group (-CH3): This is a non-polar functional group. However, its effect on the overall polarity of the amino acid is overshadowed by the polar hydroxyl group.

So, the functional groups present in the R group of threonine are the hydroxyl group and the methyl group.
