Study Notes
Biomolecules
- Biomolecules are the building blocks of life and include carbohydrates, proteins, nucleic acids, lipids, vitamins, and mineral salts.
- They interact with each other and constitute the molecular logic of life processes.
- Biochemistry is the pursuit of knowledge regarding chemical processes within living systems.
Carbohydrates
- Carbohydrates are primarily produced by plants and form a very large group of naturally occurring organic compounds.
- Common examples include cane sugar, glucose, starch, lactose, sucrose, etc.
- Their general formula is Cx(H2O)y, and were considered as hydrates of carbon.
- They are defined as optically active polyhydroxy aldehydes or ketones or the compounds which produce such units on hydrolysis.
- Some carbohydrates, like sucrose and lactose, are sweet and called sugars.
Classification of Carbohydrates
- Carbohydrates are classified based on their hydrolysis behavior.
-
Monosaccharides: Cannot be hydrolyzed further to give simpler units and are considered the building blocks of carbohydrates.
- Examples: glucose, fructose, ribose.
-
Oligosaccharides: Yield two to ten monosaccharide units upon hydrolysis.
- Further classified based on the number of monosaccharides.
- Most common are disaccharides.
- Examples: Sucrose (glucose + fructose), maltose (glucose + glucose).
-
Polysaccharides: Yield a large number of monosaccharide units upon hydrolysis.
- Examples: Starch, cellulose, glycogen.
