No idea if it's on there or not but I would assume so. Carbs, proteins, lipids, and nucelic acids (I'm assuming you meant nucleic acids as amino acids are proteins..) are the four main classes of biological molecules so I can't see why they wouldn't be on there-- and in a high degree of importance. On practice DATs, I have seen questions getting as specific about the alpha and beta isomers of glucose and what the difference in these are-- and what polysaccharides (cellulose and starch) they make.
Yep! definitely. However, there are different versions of the exam. Some may not have encountered such questions while others have. Luck of the draw I suppose. In either case, cover all bases.
