The ring forms of the 3-ketoglucose and identification of the most stable form. Introduction: Sugars containing four or more carbon atoms in their molecular structure can exist in the cyclic or the rings forms. The reversible reaction between the aldehyde or the ketone group and the hydroxyl group taking place in the presenceof water is the basis for the formation of the ring structure. As a result, hemiacetal or hemiketal is formed at the anomeric carbon.

Answer 1

Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

what is a protein that contains a b-sheet and how does the secondary structure contributes to the overall function of the protein.

draw and annotate a b-sheet and lable the hydrogen bonding. what is an example that contains the b-sheet and how the secondary structure contributes to the overall function of your example protein.

Four distinct classes of interactions (inter and intramolecular forces) contribute to a protein's tertiary and quaternary structures. Name the interaction then describe the amino acids that can form this type of interaction. Draw and annotate a diagram of the interaction between two amino acids.
