Thiol A thiol is a molecule that has a R–SH group. Thiols are like alcohols with an oxygen atom changed with a sulfur one. They have often a very strong and bad smell. Thiols are added to natural gas so that people can smell it. This is because methane does not have a smell but can explode very easily. Thiols are very easy to oxidize. They are also quite acidic, more than alcohols. When the proton is taken away by a base, the thiol can become a nucleophile. It can do reactions like nucleophilic substitution. One of the natural amino acids, cysteine, has a thiol in its structure.

Volatiles In planetary science, volatiles are the group of chemical elements and chemical compounds with low boiling points that are associated with a planet's or moon's crust or atmosphere. Examples include nitrogen, water, carbon dioxide, ammonia, hydrogen, methane and sulfur dioxide. In astrogeology, these compounds, in their solid state, often comprise large proportions of the crusts of moons and dwarf planets.

Thiol Thiols are used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the smell of natural gas is due to the smell of the thiol used as the odorant.

- Thio compounds are commonly referred to as Thio. Thioglycolic acid is the most common thio. A colorless liquid with a strong, unpleasant odor. It provides the hydrogen that causes the. reduction in permanent waving solutions. Strength of solutions is determined by the. concentration of thio. Stronger solutions have a higher concentration of. thio with a greater number of hydrogen atoms. The greater the hydrogen atoms available, the. more disulfide bonds are broken.

Thiols are the sulfur analogue of alcohols, and the word is a portmanteau of thion + alcohol, with the first word deriving from Greek θεῖον = sulfur. The –SH functional group itself is referred to as either a thiol group or a sulfhydryl group. Many thiols have strong odors resembling that of garlic. Thiols are used as odorants to assist in the detection of natural gas, and the smell of natural gas is due to the smell of the thiol used as the odorant.

Gossypol Gossypol is a natural phenol derived from the cotton plant (genus Gossypium). Gossypol is a phenolic aldehyde that permeates cells and acts as an inhibitor for several dehydrogenase enzymes. It is a yellow pigment. Among other things, it has been tested as a male oral contraceptive in China. In addition to its contraceptive properties, gossypol has also long been known to possess antimalarial properties. Other researchers are investigating the anticancer properties of gossypol.

Gladiolus Gladiolus bulbs are not true bulbs. Gladiolus bulbs, in botanical terminology, are referred to as corms. A corm is a shortened and thickened section of the stem that appears at the base of the plant. On the corm are buds for each layer of leaves.he genus Gladiolus comprises 260 species, 250 of which are native to sub-Saharan Africa, mostly South Africa. About 10 species are native to Eurasia. The impressive flower spikes of Gladioli come in a wide array of beautiful colors.

What are Lipids? Although the term lipid is sometimes used as a synonym for fats, fats are a subgroup of lipids called triglycerides. Lipids also encompass molecules such as fatty acids and their derivatives (including tri- , di- , monoglycerides, and phospholipids), as well as other sterol-containing metabolites such as cholesterol.ther major lipid classes in the fatty acid category are the fatty esters and fatty amides. Fatty esters include important biochemical intermediates such as wax esters, fatty acid thioester coenzyme A derivatives, fatty acid thioester ACP derivatives and fatty acid carnitines.

Ask Smithsonian: What Makes Skunk Spray Smell So Terrible? It doesn’t take much to have an impact. Skunk spray is a thiol, an organic compound with sulfur as a principal component. Sulfur has that classic rotten egg smell, and it’s what gives thiol its gag-inducing power. For detection purposes, thiols are added to otherwise smell-free natural gas, so that it will have a noticeable odor. In the case of skunk spray, the thiol is so potent that it can be smelled a half-mile away, says Kerns.
