Answer

The collection of various types of molecules in a cell is called cellular pool. It includes inorganic materials such as water, salts, and mineral ions, and organic compounds such as carbohydrates, lip…

Answer

Micromolecules have molecular weight less than one thousand dalton and are usually small and more soluble. Macromolecules have molecular size above 10,000 dalton. Proteins, nucleic acids, and many car…

Answer

Primary metabolites are direct products of metabolism and have known roles in normal life processes. Examples are carbohydrates, fats, amino acids, proteins, and nucleic acids. Secondary metabolites a…

Answer

General formula of carbohydrates: C_x(H_2O)_y [x, y = number of carbon and water-equivalent units]. Many carbohydrates fit this pattern, but not all do.

Answer

Deoxyribose has the molecular formula C5H10O4 and rhamnose has the molecular formula C6H12O5. These are carbohydrates, but they do not fit the general Cx(H2O)y ratio. This shows that the hydrate-of-ca…

Answer

Monosaccharides, often called simple sugars, are compounds which possess a free aldehyde (-CHO) or ketonic (=CO) group and two or more hydroxyl (-OH) groups. Their general formula is C_n(H_2O)_n [n = …

Answer

Monosaccharides may be trioses, tetroses, pentoses, hexoses, heptoses, and so on. Examples: trioses such as glyceraldehyde and dihydroxyacetone; tetroses such as erythrose and erythrulose; pentoses su…

Answer

Oligosaccharides are composed of usually 2 to 9 monosaccharide units joined by glycosidic linkage. A disaccharide yields two monosaccharides on hydrolysis, a trisaccharide yields three, and so on. Exa…
