Quantities of lactose, lactic acid, and other metabolites in yogurt
The following is quoted from this site:


  If you're lactose intolerant and looking for yogurt, go Greek. Greek yogurt, which is thicker because much of the whey, the watery part of milk, has been strained out in processing. This also removes much of the lactose. Greek yogurt supplies less than 6.8 grams of lactose per 6-ounce serving, compared to less than 8.5 grams in whole-fat yogurt or 14 grams in non-fat yogurt. Hard cheeses such as cheddar have even less lactose, between 0 to 2 grams per ounce. Milk, in comparison, has approximately 11 grams in one cup.


(Emphasis added.)

Also note that probiotic yogurt (ie: with the cultures still living intact) has the additional benefit of breaking down lactose in the gut where there is a lactase deficiency.  See here.

Sorry I don't have more specific info on other metabolites at this stage.
