Study Notes
Carbohydrates and Lipids: Key Concepts
- Carbohydrates are molecules containing carbon (C), hydrogen (H), and oxygen (O) atoms
- They exist in various forms: monosaccharides, disaccharides, oligosaccharides, and polysaccharides
- Monosaccharides have an empirical formula of (CH2O)n, where n ranges from 3 to 7 carbons
- Monosaccharides can be aldoses or ketoses and form isomers like glucose, fructose, galactose, and mannose
- They typically form ring structures through cyclisation, creating alpha and beta anomeric carbons
- Disaccharides form through glycosidic bonds, with the type of bond determined by the configuration of the hydroxyl group
- Carbohydrates can bind to noncarbohydrate structures and exist in various forms such as amylopectin, cellulose, and chitin
- Polysaccharides have diverse functions, including storage in animals (glycogen) and plants (starch), and structural roles in plants and invertebrates
- Lipids are a heterogeneous group of water-insoluble organic molecules with major roles in energy storage, cell structure, and cellular signaling
- They are classified into fatty acids, glycerol-containing lipids, non-glycerol lipids, and lipoproteins
- Fatty acids have varying chain lengths and double bond positions, with some being essential fatty acids (EFAs) that are nutritionally necessary
- Lipids such as arachidonic acid are precursors to important signaling molecules like prostaglandins and leukotrienes, with diverse physiological roles
