Citric acid, which can be obtained from lemon juice, has the molecular formula c6h8o7. a 0.250-g sample of citric acid dissolved in 25.0 ml of water requires 37.2 ml of 0.105 m naoh for complete neutralization. what number of acidic hydrogens per molecule does citric acid have?

Starch and are common polysaccharide carbohydrates found in plants. sucrose glycogen fructose cellulose

Why do you suppose the structural polysaccharide cellulose does not contain branches? why do you suppose the structural polysaccharide cellulose does not contain branches? branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby decreasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby increasing the rigidity and strength of the microfibrils. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into globules, thereby increasing the flexibility and strength of the globules. branches in the molecule would generate side chains that would almost certainly make it difficult to pack the cellulose molecules into microfibrils, thereby decreasing the rigidity and strength of the microfibrils.
