he major classes of organic compounds common to living systems are lipids, pro- teins, nucleic acids, and carbohydrates. Carbohydrates are very familiar to us- we call many of them\sugars.\ They make up a substantial portion of the food we eat and provide most of the energy that keeps the human engine running. Carbohy- drates are structural components of the walls of plant cells and the wood of trees. Genetic

Ikenes are hydrocarbons that contain a carbon-carbon double bond. A car- bon-carbon double bond is both an important structural unit and an important functional group in organic chemistry. The shape of an organic molecule is influ- enced by the presence of this bond, and the double bond is the site of most of the chem- ical reactions that alkenes undergo. Some representative alkenes include isobutylene(an industrial chemical), a-pinene (a fragrant liquid obtained from pine trees), and farnesene (a naturally occurring alkene with three double bonds

An ICBM with a range of 6500 miles has a stagnation temperature of 12,000 ºF, 2000 ºF hotter than the surface of the sun Calculations showed that the optimum design for structural strength, resistance to heating, and free flight stability was a long, needle nosed reentry body

Principal Aim To assess the strength changes, and associated change in fracture risk, due to structural alterations in the proximal femora of astronauts experiencing long￾term weightlessness
