Study Notes
Organic Chemistry
- Organic chemistry studies organic compounds.
- All organic compounds contain carbon.
- Many organic compounds originate from living things.
- Most naturally occurring compounds are organic.
Carbohydrates
- Carbohydrates are composed of carbon, hydrogen, and oxygen in a 1:2:1 ratio.
- Sugars and starches are carbohydrates.
- Living things use carbohydrates for energy and structural support.
- Monosaccharides: Simple sugars, include glucose and fructose.
- Disaccharides: Two monosaccharides bonded together, examples include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).
- Polysaccharides: Made of thousands of monosaccharides linked together. Examples include starch (found in wheat, rice, corn, and potatoes), glycogen (storage form in animals), and cellulose (plant structural component).
Lipids
- Lipids are organic compounds (including fats, oils, waxes, and steroids) consisting primarily of carbon, hydrogen, and oxygen.
- Lipids have a similar ratio of these elements to carbohydrates, but differ in the specifics.
- Fats: Composed of glycerol and 3 fatty acids. Used for energy storage and insulation. Excess carbohydrates are converted to fats.
- Fatty acids are chains of carbon atoms ending in an acid group. The structure of the fatty acids determines the characteristics of the fat. Animals typically contain approximately 30 different fatty acids.
Other Organic Compounds
- Phospholipids: Lipids containing phosphorus. Major components of cell membranes.
- Steroids: Lipids with four linked carbon rings. Examples include cholesterol and hormones.
- Waxes: Organic compounds made from fatty acids and alcohols.
- Proteins: Organic compounds made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulfur. Crucial for all living things, including muscles, hair, and skin. Made from amino acids.
- Amino Acids: Building blocks of proteins. About 20 different amino acids are used to create different proteins. Amino acids contain an amino group (-NH₂), a carboxyl group (-COOH), and a unique side group.
- Covalent bonds connect amino acids together into polypeptide chains, forming proteins.
- Nucleic Acids: Large, complex molecules made of carbon, hydrogen, oxygen, nitrogen, and phosphorus. Examples include DNA and RNA, involved in genetic material.
