Content Objective: Explore the versatility of carbon in forming diverse organic compounds and understand its fundamental role in life processes. Focus on the structure and function of monosaccharides, their formation through condensation reactions, and breakdown via hydrolysis.
Language Objective: Develop the ability to articulate and diagrammatically represent the complex nature of carbon compounds and their biochemical reactions. Enhance skills in using scientific terminology to describe and explain the structure, function, and transformations of monosaccharides.
Syllabus Details:
B1.1.1—Chemical properties of a carbon atom allowing for the formation of diverse compounds upon which life is based - "Students should understand the nature of a covalent bond. Students should also understand that a carbon atom can form up to four single bonds or a combination of single and double bonds with other carbon atoms or atoms of other non-metallic elements. Include among the diversity of carbon compounds examples of molecules with branched or unbranched chains and single or multiple rings. Students should be able to draw / model bio molecules and be familiar with condensation + hydrolysis reactions. "
B1.1.2—Production of macromolecules by condensation reactions that link monomers to form a polymer - "Students should be familiar with examples of polysaccharides, polypeptides and nucleic acids."
B1.1.3—Digestion of polymers into monomers by hydrolysis reactions - "Water molecules are split to provide the -H and -OH groups that are incorporated to produce monomers, hence the name of this type of reaction."
B1.1.4—Form and function of monosaccharides - "Students should be able to recognize pentoses and hexoses as monosaccharides from molecular diagrams showing them in the ring forms. Use glucose as an example of the link between the properties of a monosaccharide and how it is used, emphasizing solubility, transportability, chemical stability and the yield of energy from oxidation as properties."
