Just two questions, 1. All different kinds of enzymes have a specific charge, right? 2. When the Isoelectric point of an enzyme is at 0, this is at its optimum for enzyme activity? Thanks

Hi Guys, I was wondering if you get any precipitate from 2ml Lactose 3ml Lactase, and 2ml Benedicts. Lactose should hydrolyse into Glucose + Galactose. Will Benedict's copper(II) ions (Cu2+) get reduced because of the Glucose and precipitate? If yes, about how much of precipitate would I get in terms of milligrams with those kind of values. Also does light affect the speed of oxidation. If yes, would it apply to the chemical reaction that takes place with Bendict's solution and glucose?\\ Thanks
