Answer:
It is the arrangement and order of the parts within a whole. It can also be understood as a system of coherent linked concepts, whose objective is to specify the essence of the object of study.
The structure is the set of elements that characterize a certain area of reality or system. The structural elements are permanent and basic, they are not subject to circumstantial or circumstantial considerations, but they are the essence and the raison d'être of the same system.
The elements that make up a structure are defined by some basic or characteristic features, and they are differentiated or individualized from each other by what we call distinctive features. There will be distinctive features that will allow us to isolate groups, groups between groups and individuals between groups. This concept is applicable to all sciences, and among them to social sciences, where they allow analysis of the groups that integrate them and the dynamics they can generate.

Answer: position of the carbonyl carbon
Explanation:
In the linear structure of sugars having an aldehyde group, are called aldoses, and sugars having a keto group are called ketoses.
Like adehydes H-C=O the carbonyl carbon is the first/last in the chain it is bounded to Hydrogen, double bounded to oxygen and a single bond to the chain. An aldose linear sugar like D-glucose have the carbonyl carbon as it first carbon.
But ketones R-COR the carbonyl carbon is in between the chain, it is bounded to two carbons on both sides. Like D-fructose the keto carbon is the second carbon.
In a open ring structure the 1st carbon, adehyde group is condensed with the hydroxy group (OH) of the 5th carbon forming a ring. The first carbon is now bound to the chain, Hydrogen, OH and oxygen which forms the ring.
In the keto open ring structure of D-fructose, the second carbon(keto group) is condensed with the OH of the 5th carbon
