Often times, a carbohydrate exists in a cyclic or an acyclic form. carbon transforms into a new stereocenter. Cyclization causes the formation of 2 new diasteriomers. of a certain group (discussed later) to the new stereocenter.
My favorite place to visit is in West Bend, Iowa. There is a place called The Grotto of Redemption it was built by hand from one man. It has the different stages from the bible.
We visited the castle, the Danube River (gorgous) and walked around (I was there with native friends so it was much easier to figure out what was best to see.) My favorite part of Slovakia is not only the scenery, but the food. We went to Slovak Pub and tried halusky....you must eat that. It's very yummy, and if you can, taste the hot chocolate when you're in Svk..it's to die for.
