    Identification of Macromolecules Introduction The most common macromolecules found in living organisms are lipids‚ carbohydrates‚ proteins and nucleic acids. Briefly‚ the meaning of macromolecules is that they normally contain two or more molecules in them and their main functions are to store energy‚ information and much more. Most foods are known to be combinations of macromolecules. While some of these compounds can be detected by taste tests‚ many cannot. Scientists then use certain

    Glucose +Glucosemaltose Starch * It acts as a store of energy which can be converted back into glucose when required. It can be found in 2 forms: * The polysaccharides of amylose (50-500 glucose units in a straight line) * Amylopectin (Which contains up to 100000 glucose units in a branch like structure) Polysaccharides Glycogen: is the bodies’ equivalent to starch. It is stored in the liver and muscles and is Brocken down into glucose when energy is required. Pectin: pectin substances

    The two types of cell walls are primary cell wall and secondary cell wall. 4. What are the most abundance components of the CELL WALL? And what are the three types? Also list their functions. The most abundant component of the cell wall is Polysaccharide. The three are: Cellulose‚ Hemicellulose and Pectin. Cellulose has crystalline aggregates that give the cell wall its resistance; hemicellulose provides structure‚ regulation and storage to the cell wall and pectin is used as a gel agent. 5

    Living organisms are composed of part water and part chemicals. The chemicals that help make up life are constructed mainly of carbon. A compound that has carbon in its composition is called an organic compound. Organic compounds also usually contain hydrogen atoms. Even though life is very complex‚ all large molecules that make up life are categorized into four large classes: lipids‚ protein‚ carbohydrates‚ and nucleic acids. These four molecules are known as macromolecules‚ due to their large size

    nutrients in preparation for absorption. GI tract is the flexible muscular tube from mouth to anus. The digestion of carbohydrates begin in the mouth‚ where an enzyme‚ salivary amylase (α-amylase;ptyalin) starts to breaking the polysaccharides (starch) into short polysaccharides (dextrin). Dextrin is a partial degradation of starch‚ shorter chains of maltose units. Salivary amylase is inactivated by stomach acid in the stomach and to a small extent‚ it continues breaking down starch (but there’s no enzymatic
