BIOL 1001 Chapter : Molecules Bio Notes
Document Summary
Molecules: organic, cho, carbon backbone, glucose, c6h12o6, carbohydrates, proteins, lipids, nucleic acids. Inorganic: lacks carbon backbone, water, h20, salts, nacl, acids, bases, metals, co2, no2, equally important in living systems. Figure 3-2: single double and triple bonding patters. Loss of water, remove h2o: polymers ---->>> monomers, reaction needed: hydrolysis, add h2o, figure 3-3, table 3-2, need to know, monosaccharide, glucose, fructose. Fruit sugar: galactose, milk sugar, disaccharides, sucrose, glucose/fructose, maltose, glucose/glucose, lactose, glucose/galactose, polysaccharides, starch, animals, cellulose. Found in plants: cant digest it, chitin. Intracellular messengers: amp, nucleic acids, dna & rna, dna, two stranded, twisted molecule. Forms a double helix: bond together by hydrogen bonds, blueprint, rna, copied from dna, dna --->>> rna --->>> proteins. Lipids: fats, oils, waxes, steroids, phospholipids, glycerol + 3 fatty acid chains, triglyceride. Loss of 3 waters: hormones in the body, vital component of the cells, fats are very energy rich and give more energy than carbs and proteins, saturated, many hydrogen molecules.
