Document Summary
Ionic bonds are strong because they form crystal lattices. A crystal lattice is when positive and negative ions arrange themselves into an ionic crystal lattice. They are held by the balance of attractive bonds and electrical repulsion. (each ion had the greatest possible number of oppositely charged ions close, while keeping ions with the same charge as far as possible. Polar covalent bond: a covalent bond formed between atoms with different electronegativity"s. Non polar solvents dissolve non polar solvents (example oil in gasoline) Anabolic reaction: building larger molecules from smaller pieces requires energy and results in water production: requires enzymes. Ionic bonds (between oppositely charged r groups: hydrogen bonds (between polar amino acids, disulfide bridges, van der wals forces aka london forces (between non- polar amino acids) Quaternary structure- if two or more polypeptides all combine to form a functional protein: what affects protein structure, ph and temperature, environment changes protein may become denatured, meaning biological function will not work.
