ORGANIC MOLECULE SUBUNIT NUCLEOTIDE SUBUNITS (A, T, G, C, or U) MAKES THIS MACROMOLECULE NUCLEIC ACIDS (DNA OR RNA) PROTEINS AMINO ACIDS (20 different R groups) GLUCOSE TRICLYCERIDE AND STEROID CARBOHYDRATES MONOSACCHARIDES= 1 sugar Ex: glucose, fructose, ribose, deoxyribose 1 C: 2 H: 1 O Mostly CARBON & HYDROGEN ATOMS in long chains or rings with very little oxygen COMPLEX CARB’s DISACCHARIDES= 2 sugars EX :sucrose, lactose) OLIGOSACCHARIDES= few (2-10 sugars) parts of GLYCOPROTEINS POLYSACCHARIDES = many sugars Ex : glycogen, starch, cellulose LIPIDS Includes: Fats, oils, waxes, steroids HYDROPHOBIC ATP = ADENOSINE TRIPHOSPHATE Stores energy for cell activities PHOSPHOLIPIDS (polar head & 2 non-polar lipid tails) Makes cell membranes GLYCOPROTEINS (Protein with sugars attached) Cell identity; Recognize of “SELF”
