- Can you please identify the name of each of the structures of sugar and identify as reducing or nonreducing sugar of a,b,c and d? The picture is posted. One of the structures may be not identified from the usual structures of disaccharides.Briefly and in simple terms, describe the glycoside bond connecting two monosaccharides in a di- or polysaccharide.The following is true for the hetero-polysaccharide, except: Hyaluronic acid is an examples They can be branched or unbranched Different sugar units attached together Same type of sugar units attached together
- Name the three different polysaccharides. explain their structure (and their differences) and where they occur (where you find them).Suppose that the given peptide below is a segment in a globular protein's primary structure. Determine what would most likely be the type of secondary structure that it will form. Explain. T-L-S-A-R-I-D-VThe monosaccharide shown below polymerizes to form a polysaccharide where each sugar residue is linked to each other by a 8 (1 + 4) linkage.

- Oligosaccharides are usually attached to proteins on loops or turns that project from the protein surface. Explain why this is the case.The structure below shows that of a trisaccharide that is composed of (going from top left to bottom right) galactose, glucose, and fructose. More specifically, the component monosaccharides are [D-galactose, L-galactose], [D-glucose, L-glucose], and [D-fructose, L-fructose] .A polysaccharide is found in the shells of arthropods (e.g.,lobsters and grasshoppers) and of mollusks (e.g., oysters andsnails). It can be obtained from these sources by soaking theshells in cold dilute hydrochloric acid to dissolve the calciumcarbonate. The threadlike substance formed is composed oflinear long-chain molecules. Hydrolysis with boiling acidgives d-glucosamine and acetic acid in equimolar amounts.Milder enzymatic hydrolysis gives N-acetyl-d-glucosamineas the sole product. The polysaccharide’s linkages are identical to those of cellulose. What is the structure of thispolymer?
