The sweetness of lactose, relative to that of other simple sugars. It is only 20–30% of that of sucrose and this is one of the reasons that lactose is a suitable carbohydrate in infant formulas. It is thought that a high sweetness could encourage appetite and overeating and lead to the...
4-Dimethylaminopyridine (DMAP) is a derivative of pyridine with the chemical formula (CH3)2NC5H4N. This colourless solid is of interest because it is more basic than pyridine, owing to the resonance stabilisation from the NMe2 substituent. Chemical Properties DMAP (m.p. 112-113°C) and PPY...
