BSC 1005 Lecture Notes - Lecture 4: Ribose, Maltose, Chitin
Document Summary
Biological molecules, monomers, polymers, saccharides, fats, fatty acids, phospholipids, waxes, Carbon atoms form the backbone of biological molecules called organic compounds. Dissolved sugars, fatty acids, aminoacids, and nucleotides are the organic compounds found in cells. They are the building blocks for the following 4 biological molecules. The most abundant biological molecule composed of many sugar units. All cells use them as structural materials, transportable packets of energy, and stored forms of energy. Monosaccharides (one monomer of sugar) glucose, ribose, deoxy ribose, fructose, galactose. Disaccharides (two monomers of sugar) lactose, sucrose, maltose. Polysaccharides (many monomers of sugar) starch, cellulose, glycogen, chitin. Greasy or oily compounds, readily dissolve in one another, but not so in water. Hydrophobic: hydro = water , phobic = repel. Certain lipids with fatty acid tail form the main reservoirs of stored energy, structural materials in cell membranes and surface coatings. Structural materials in cell membranes (phospholipids) which protect body surfaces.
