The structure of biological molecules determines its chemica

The structure of biological molecules determines its chemical properties, role/function and affects its location in cells. Determine the properties of these biological molecules by reading pages 47-62 in Chapter 2, the lecture notes and perhaps other sources. Note the cellular location of each type of molecules is not always stated in the book and may have to inferred or found somewhere else. Chemical properties: Charged, polar, nonpolar, or amphipathic, or hydrophobic. Location(s) found in cells: In cytosol, inside an organelle, in a membrane (cell or organelle membrane), or on outside of cell.

Solution

1. Monosaccharide and disaccharides - function - chief source of energy, intermediates in biosynthesis of fats and protein, they act as cell to cell communicator, renewation of immune system. Location-animal cell- in liver and mitochondria of plant cell.

2. Oliosacchrides- chemcal property polar, functon- cell adhesin, cell response and immune system formation, location cell wall

Polysaccharides- function - antantcoagulant, reservation of food. Location cell wall

phospholipid- chemically they are polar and non polar, function cell wall formation , location cell membrane

steroids- chemical nature non polar, function catabolism and anabolisam, location cell membrane

protein are polar in nature, function -dna rna formation, reaction catalyzation, location within cell membrane

DNA RNA- chemically they are polar in nature, fuction transfer of genetic information , location nucleous , cytoplasm
