Macromolecule Report Monomer units of biological macromolecules have heads and tails. When they polymerize in a head-to-tail fashion‚ the resulting polymers also have heads and tails. These macromolecules are polar because they are formed by head to tail condensation of polar monomers. Making Glucose: Green plants manufacture glucose through a process that requires light‚ known as photosynthesis. This process takes place in the leaf chloroplasts. Carbon dioxide and water molecules enter a sequence

the three conventional biopolymers (nucleic acids‚ lipids‚ proteins and carbohydrates)‚ as well as non-polymeric molecules with large molecular mass such as lipids and macrocycles. The individual constituent molecules of macromolecules are called monomers(mono=single‚ meros=part). Usage The term macromolecule was coined by Nobel laureate Hermann Staudinger in the 1920s‚ although his first relevant publication on this field only mentions high molecular compounds (in excess of 1‚000 atoms).At that

apart and attach themselves to the ends of shorter polymers. Hydrolysis plays an important role in our lives and in the lives of every living thing on earth. Living organisms rely on digestion (hydrolysis) to convert food energy from polymers into monomers‚ which are easier for our cells to absorb. This study was conducted to show how polysaccharides are broken down by organisms to absorb nutrients through hydrolysis. We used different methods to show how different tests involving heat‚ acid‚ saliva

establish the type of foams in terms rigidity or flexibility. THEORY Polyurethanes‚ also known as polycarbamates‚ belong to a larger class of compounds called polymers. Polymers are macromolecules made up of smaller‚ repeating units known as monomers. Generally‚ they consist of a primary long-chain backbone molecule with attached side groups. The preparation of polyurethanes is a process of polymerisation whereby a diisocyanate and a dihydroxyl compound react together. Polyurethanes by definition

by High density polyethylene (HDPE)‚ General Purpose polystyrene (GPPS) and Polypropylene (PP) in descending order. The reason why HIPS has a higher impact strength than HDPE is because HIPS is made of a larger monomer‚ styrene (C8H8 or C6H5CH=CH2) while HDPE is made of a smaller monomer‚ ethylene (C2H4 or H2C=CH2). Additionally‚ HDPE is a linear polymer. HDPE is made of closely packed structure of ethylene hydrocarbon (C2H4n.H2) which undergoes a catalytic process. There are no branching in the
