Due to having 4 valence electrons What is a long chain of carbons called? - Answers Polymers What is a cyclic compound? - Answers Carbons joined together in a closed chain What are carbon compounds called? - Answers Alkanes Condensed structures give a better idea of a molecules structure, compared to chemical formula. T or F - Answers T Structural formula gives an even better idea of a molecules structure, compared to chemical formula - Answers T Advantage of cyclic carbon compounds - Answers They are more restricted in their movements and orientation - advantageous for building structures and maintaining shape Carbon can form double and triple bonds with other carbon atoms or atoms of other elements. T or F - Answers T Line-bond Drawing - Answers Most efficient method to show structure, but requires the most interpretation. Functional group - Answers specific arrangement of atoms; they define the chemistry of the molecule and control the properties of the compound. What dictates the chemical and physical properties of compounds, including biochemical compounds? - Answers The structure Biomolecules - Answers Molecules that are part of the cell or molecules that are excreted by cells. Macromolecules - Answers large biomolecules Molecular mass of a Macromolecule - Answers 5,000 g/mol or greater What are daltons used for? - Answers Larger molecules use Daltons for mass. 1 Da = 1 g/mol Larger molecules develop more complex structures. T or F - Answers T What is 25,000 Da in Kilodaltons - Answers 25 kDa
