Document Summary

Dehydration reaction: bond that forms that drops an h2o molecule. Monosaccharides simple sugars: most common is c6h12o6 one carbonyl group and multiple hydroxyl group. Disaccharides double sugars joined by glucose linkage covalent bond formed between two monosaccharides by dehydration reaction two monosaccharides joined by covalent bond. Polysaccharides linked together by two glucose molecules: macromolecules formed by hundreds of glycolysis linkages. Storage polysaccharides plants stores sugars, mainly starch, for later use animals store sugars called glycogen deplete after a day unless replenished stored usually in liver and muscle cells. Structural polysaccharides used to make strong materials like cell walls cellulose: most abundant organic compound on earth chitin: carbohydrate used by arthropods to build exoskeleton. Fats (triglyceride: main purpose is to store energy. Constructed from two kinds of smaller molecules glycerol: an alcohol fatty acids: long carbon skeleton chain: water molecules hydrogen bond to each other and exclude the fats think of olive oil in vinegar.
