Why are polysaccharides insoluble? - The Student Room
Polysaccharides tend to be long molecules consisting of many simple monosaccharides (monomers). Two monosaccharides may undergo a condensation reaction in which two free hydroxyl groups react to form a glycosidic bond (-O-) and a molecule of water is eliminated. As such, polysaccharides tend to be large and non-polar and therefore do not ...

2016年10月5日 · Monosaccharides e.g. glucose, fructose and disaccharides e.g. lactose, maltose, are all soluble in water, so they will not produce an emulsion i.e. will not give a false positive result. Proteins and nucleic acids are not soluble in water as they are v large molecules, they will not emulsify (so no false positive), rather they will form a ...

Biomedical Science V Biochemistry PLEASE HELP ... - The Student …
As nicatre hints at, biomedical science is obviously a lot more human-centric. If you do biochemistry then there's plenty of e.g. plant biochemistry (i.e. the more complicated, interesting stuff) If you're sort of set on doing medicine after anyway, then biomedicine would be the more useful degree, but biochemistry will get you just as far.
