About 19% of the calories in chickpeas come from proteins (12 gram per cup). That's pretty much. But it's less than say lentils (41%), lima beans, or peas (43%). (In grams per cup that's, respectively, 18 grams, 12 grams, and 10 grams.)
As for hummus, the brand I buy (I think there's a lot of nutritional variation from brand to brand) has 21% of its calories come from proteins (18 grams per cup), but a whopping 69% from fat.
