BIOMOLECULES 1.What are macromolecules? Give examples. Macromolecules are large complex molecules that occur in colloidal state in intercellular fluid. They are formed by the polymerization of low molecular weight micromolecules. Polysaccharides‚ proteins‚ and nucleic acids are common examples of macromolecules. 2. Illustrate a glycosidic‚ peptide and a phospho-diester bond. (a) Glycosidic bond is formed normally between carbon atoms‚ 1 and 4‚ of neighbouring monosaccharide units. (b) Peptide

different substances. Introduction Macromolecules are in all forms of life. These organic compounds are carbohydrates‚ lipids‚ proteins‚ and nucleic acids. These are monomers and they link together into long chains that form polymers. Different reagents can be used to find the presence of these macromolecules. Proteins are made of carbon‚ hydrogen‚ oxygen‚ nitrogen‚ and sometimes sulfur. Proteins are covalently bonded in chains as polymers of amino acids. These bonds are called peptide bonds.

The limiting reagent it CuCl2 because it is the one that will run out first compared to the .009 moles of Na2Cl3‚ which it the excess reagent because it is a higher amount of moles compared to the .007 moles of the CuCl2. The amount of excess reagent in grams that should remain in solution if the theoretical yield of CuCO3 is produced is: 1 mole of CuCl2 (63.55) +(2*35.45) =134

relate this gruesome glimpse into my subconscious because I know precisely when the dreams began. It was eight years ago‚ when a professional player — a former NFL defensive lineman — suffered a fatal spine injury on the field.
