Study Notes
Biochemistry Overview
- Biochemistry studies the chemical processes within and relating to living organisms
- Key components include carbohydrates, lipids, proteins, vitamins, minerals, enzymes, endocrine glands and hormones, and human metabolism
Carbohydrates
- Composed of carbon, hydrogen, and oxygen (C:H:O ratio of 1:2:1)
- Function as a primary energy source
- Classified based on the number of sugar units:
- Monosaccharides (1 sugar unit): Simplest form, e.g., glucose, fructose, galactose
- Disaccharides (2 sugar units): Formed by joining two monosaccharides, e.g., sucrose, maltose, lactose
- Oligosaccharides (3-10 sugar units): Short chains of monosaccharides
- Polysaccharides (>10 sugar units): Large chains of monosaccharides, e.g., starch, cellulose, glycogen, dextrin, dextran
- General formula for carbohydrates: CnH2nOn
- General formula for glucose with 6 carbon atoms: C6H12O6
- Carbohydrates are polyhydroxy aldehydes or ketones (have more than one -OH group)
- Can exist in a long-chain or ring structure
- Important components of nucleic acids (DNA, RNA)
- Make up a significant portion of plant dry weight (~¼)
- Main source of energy for the body: Glucose + O2 → CO2 + H2O + Energy
- Monosaccharides are the simplest form of carbohydrates and cannot be broken down further
- Nomenclature: Function group and number of carbon atoms (e.g., aldohexose, ketohexose)
Disaccharides
- Formed by joining two monosaccharides through dehydration synthesis
- Types include:
- Maltose (glucose + glucose)
- Sucrose (glucose + fructose)
- Lactose (glucose + galactose)
Polysaccharides
- Important energy storage molecules (starch and glycogen) or structural components (cellulose)
- Homopolysaccharides contain one type of sugar unit (e.g., starch, cellulose, glycogen, dextrin, dextran)
- Heteropolysaccharides contain more than one type of sugar unit (e.g., heparin)
