In condensation between two sugars, an ( OH, NH2, NH4, H2O ) group and ( H, N, F, C ) group leave their monomers and become ( water, carbon dioxide, ammonia, hydrogen gas ). The monomers then join, forming a ( C-O-C, C-O-H, C-N-C, O=N=O ) bond. This is called a ( glycosidic, glycolic, amide, condensation ) bond. The resulting molecule can vary, for example:
a-glucose + a-glucose = ( maltose, sucrose, lactose, cellobiose )
a-glucose + fructose = ( sucrose, maltose, lactose, cellobiose )
a-glucose + B-galactose = ( lactose, maltose, sucrose, cellobiose )
B-glucose + B-glucose = ( cellobiose, maltose, sucrose, lactose )

( Starch, Sucrose, Sap, Glycogen ) is the main form of carbohydrate store in plants. It's made of ( amylose, cellulose, glycogen, triglycerides ) and ( amylopectin, disaccharide, insulin, cellulose ), which are ( long, short, double ) chain ( a-Glucose, B-Glucose, Sucrose, a-Glucose and B-Galactose ) chains. While ( amylose, glycogen, cellulose, triglycerides ) and ( amylopectin, disaccharides, insulin, cellulose ) both have ( 1,4-glycosidic bonds, 1,3-glycosidic bonds, 1,4-peptide bonds ), ( amylose, glycogen, cellulose, triglycerides ) coils into a helical shape, but ( amylopectin, disaccharide, insulin, cellulose ) is branched out.
Starch is ( insoluble, soluble, inert, liquid ) so as to not affect the water potential of the cells it's stored in.

Select from the dropdown lists to complete the text.

( Glycogen, Cellulose, Glucose, Glucagon ) is the main type of carbohydrate store in animals. It's a ( multi-branched, unbranched, granular, insoluble ) ( a-Glucose, B-Glucose, Maltose ) polymer with 1,4- and 1,6-glycosidic bonds. It's highly ( compact, coiled ) so optimal for storage.

Explanation

Energy storage molecule
Highly fibrous
Insoluble
a-Glucose polymer
Unbranched chain called microfibril
