Document Summary
All have the same basic structure: amino group, carboxylic acid group, h, r side-chain. To determine properties, only look at r-group: r side-chains. Can act like acids or bases, depending on ph of environment. What property do amino acids have when polar and non polar chains are present: they are polar. Monosaccharide: name of monomer: usually multiple of ch2o, glucose is the most common monosaccharide, glycogen: storage for animals, starch: storage for animals. Glyosidic linkage: bonds between monosaccharides: covalent. Nucleotide: name of monomer: nitrogenous base. Purines: two c-rings, includes adenine and guanine. Polynucleotide: name of polymer: dna and rna are two polynucleotides found in living things. Dna: deoxyribonucleic acid contains adenine, thymine, cytosine, guanine. Rna: ribonucleic acid contains adenine, uracil, cytosine, guanine. Phosphodiester linkage: holds sugar-phosphate backbone together: covalent. Sneak peak: existence of base pairs allows copying. Only biomolecules that aren"t true polymers o. Not usually big enough to be macromolecules. Common lipids: waxes, fats, phospholipids, steroids.
