When reviewing the citric acid cycle, I find names like glutarate and succinate to be helpful in thinking about the structure of the molecules because I was taught about the sequential dicarboxylic acid naming scheme: oxalic (2 carbon), malonic (3C), succinic (4C), glutaric (5C) etc.
But I often struggle with fumarate and malate because I have not learned the numbering or nomenclature system that these names are derived from. Can someone point me in the right direction so that I can learn the background behind these names?
Knowing that will be helpful to my recall of the molecular structure. Then I can stop memorizing and start understanding.
