Question: Garlic contains the molecule alliin. When garlic is crushed or chopped, a reaction occurs that converts alliin into the molecule allicin, which is primarily responsible for the aroma we associate with garlic. Describe the molecular geometry about the sulfur atoms in both compounds. Select all that apply.

Crushed bauxite is treated with moderately concentrated sodium hydroxide solution. The concentration, temperature and pressure used depend on the source of the bauxite and exactly what form of aluminum oxide it contains. Temperatures are typically from 140°C to 240°C; pressures can be up to about 35 atmospheres.

The characteristic aroma of garlic is due to sulfur-containing volatile compounds that compose 1% of its dry weight (Fenwick and Hanley 1985).These volatile compounds are produced from their non-volatile precursors namely γ-glutamyl-S-alk(en)yl-L-cysteines and S-alk(en)yl-L-cysteine sulfoxides (Butt et al. 2009).OSCs are generally …

Scientists have seen many kinds of sulfur on Mars; the region Curiosity found this rock is, in fact, known for being rich in sulfates – a kind of sulfur-based salt that was left behind as water dried up on this part of the Red Planet billions of years ago.

Among several recent findings, the Mars Curiosity rover has found rocks made of pure sulfur — a first on the Red Planet. Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals.
