Concept explainers
(a)
Interpretation: To draw the structural formula for oxaloacetic acid.
Concept introduction: There are a number of
Polyfunctional carboxylate ions act as a substrate in the metabolic pathways and can be divided into two parts depending upon the parent
Oxaloacetic acid is an unsaturated derivative of succinic acid. The structure of succinic acid is:
(b)
Interpretation: To draw the structural formula for oxaloacetate ion.
Concept introduction: There are a number of metabolic reaction that occur in the human body for completion of functions. During these metabolic reactions, the various metabolic intermediates are formed for the short time to complete the reactions. Polyfunctional carboxylate ions are also the metabolic intermediate formed during metabolic pathways.
Polyfunctional carboxylate ions act as a substrate in the metabolic pathways and can be divided into two parts depending upon the parent carboxylic acid. The first class consists of malate, oxaloacetate and fumarate ion which are derivative of succinic acid.
(c)
Interpretation: To draw the structural formula for citric acid.
