practice for putting people under while they undergo a surgery. In the 1860s this practice had just been developed; therefore‚ the simplicity was very evident.

function of living cells. Examples of lipids include fats‚ oils‚ waxes‚ certain vitamins‚ hormones and most of the non-protein membrane of cells. Lipids are not soluble in water. They are non-polar and are thus soluble in nonpolar environments like in chloroform but not soluble in polar environments like water. Lipids have mainly hydrocarbons in their composition and are highly reduced forms of carbon. When metabolized‚ lipids are oxidized to release large amounts of energy and thus are useful to living
