Document Summary
Macromolecules: large molecule that is often formed by a string of molecules. Chapter 3: molecules of cells: primary fuel for organisms, disaccharides. Lipids: provide more than 2x as much energy as carbohydrates and proteins, fats. Saturated: one carbon binds to two hydrogens butter. Unsaturated: one carbon binds to one hydrogen oil: sterols. Regulate sexual development, maturation, and sex cell production. Usually good with keeping water out as it is hydrophilic head and hydrophobic tail: related to obesity. Health problems: heart attack (arteries clog up) Proteins: serve as building block, protective, regulatory, contractile, and transport, amino acids (monomer) 8 obtained from diet: denature: disrupts protein shape and function. More than 70 degrees and change ph. Nucleic acid: dna double stranded. Phosphate group, sugar, nitrogenous base (monomer: rna single stranded. No thymine but instead uracil: function: encodes all information for a species.
