Study Notes
Carbohydrates in Biochemistry
- Carbohydrates are essential biochemical substances made up of carbon, hydrogen, and oxygen.
- They are categorized based on the number of monosaccharide units:
- Monosaccharides (single units)
- Oligosaccharides (2-10 units)
- Polysaccharides (more than 10 units)
Oligosaccharides
- Composed of 2 to 10 monosaccharide units linked by covalent bonds.
- Commonly found in both plants and the human body, serving structural and regulatory roles.
- Can be further classified:
- Disaccharides: Contain two monosaccharides; examples include sucrose (glucose + fructose) and lactose (glucose + galactose).
- Often water-soluble and crystalline in nature.
Hydrolysis of Carbohydrates
- Disaccharides can undergo hydrolysis, breaking down into their monosaccharide components.
- Hydrolysis plays a crucial role in the digestion and absorption of carbohydrates in the human body.
Non-reducing Sugars
- Some disaccharides, like sucrose, are categorized as non-reducing sugars, which do not have a free aldehyde or ketone group.
Bioinorganic and Bioorganic Substances
- Bioinorganic substances: Include water and inorganic salts, vital for biological functions.
- Bioorganic substances: Larger biomolecules including carbohydrates, proteins, and lipids, crucial for life forms.
