Chiral carbons in cyclic compounds
WebKey Terms. Chiral carbon (asymmetric carbon) :A carbon that is attached to four different types of atoms or groups of atoms. Absolute configuration: The three-dimensional arrangement of the groups attached to the chiral carbon in a carbohydrate. Stereoisomers (aka optical isomers): Any of two or more compounds with identical molecular formulas ... WebThe larger red arrow marks the higher priority carbon (C,C,C). The smaller red arrow points to the lower priority[carbon (C,H,H). For the blue arrows, sulfur takes priority over carbon. [Addendum: Strictly speaking, the two blue arrows should point to the methylene groups next to the blue sp 2 carbon such that C(S,H,H) > C(C,H,H).
