Abstract:
It is still a challenge to identify mixed polysaccharides isolated from biological tissues. The present study aimed to develop a protocol that allowed for quick characterization of mixed polysaccharides by selecting Cyclina sinensis polysaccharides as test beds. Disaccharides were gradually released by graded acid hydrolysis, separated with 3 kDa molecular weight cut-off membrane, and analyzed by HPLC-ESI-MSn. Furthermore, the monosaccharide composition of the filtrate during the gradient acid hydrolysis process and the final retentate were also determined to provide composition information of these disaccharides. Thus, 6 disaccharides were detected and identified, indicating the existence of polysaccharides constructed of corresponding repeated disaccharide fragments in C. sinensis. The present study demonstrated a potential strategy to characterize mixed polysaccharides without separation and purification.

If one phosphate group is removed, a molecule of ADP—adenosine diphosphate—remains, along with inorganic phosphate. ADP can be further hydrolyzed to AMP—adenosine...
Acid Halides to Carboxylic Acids: Hydrolysis
As shown below, the mechanism involves a nucleophilic attack by water at the carbonyl carbon to form a tetrahedral intermediate. This is followed by the reformation of the carbon–oxygen π bond along with the departure of a halide ion. A final proton transfer step yields carboxylic...
Hydrolysis
Hydrolysis is a chemical reaction in which the addition of water breaks down a polymer into its simpler monomer units. For example, peptides break into amino acids, carbohydrates into simple sugars, and DNA into nucleotides. Enzymes often facilitate these processes.
Hydrolysis Reverses Dehydration Synthesis
Complex carbohydrates can be broken down by breaking the bonds between individual sugar units. The reaction breaks a glycosidic bond as water is added to the compound. The...
Amides to Carboxylic Acids: Hydrolysis
Acid-catalyzed hydrolysis:
Hydrolysis of amides under acidic conditions yields carboxylic acids. Since the reaction occurs slowly, hydrolysis requires the conditions of heat.
The mechanism begins with the protonation of the carbonyl oxygen by the acid catalyst. The protonation makes the amide carbonyl carbon more...

Esters to Carboxylic Acids: Acid-Catalyzed Hydrolysis
During hydrolysis, the ester is first activated towards nucleophilic attack through the protonation of the carboxyl oxygen atom by the acid catalyst. The protonation makes the ester carbonyl carbon more electrophilic. In the next step, water acts as a nucleophile and adds to the...
