This is an example of developmental homology. Studying embryological development of living things provides clues to the evolution of present-day organisms. During some stages of development, organisms exhibit ancestral features in whole or incomplete form. Homologous structures are those structures whose underlying similarity arises from their being derived from a common ancestral origin while analogous structure are those whose similarity comes from their performing of a similar function.
An open-chain structure of glucose presents unbranched backbone of six carbon atoms, where C1 atom has functional group, aldehyde and glucose failed to undergo typical aldehyde reactions. Glucose has no end functional groups in a ring structure. The open-chain form of glucose makes up less than 3% of the glucose molecules in a water solution.
