Both are made out of Keratin, a fibrous sulphur-containing protein.

There's been a bit of disagreement on what causes the smell, but it's likely to be mercaptan, a sulphur-containing compound.

Extractions tests made in Trinidad indicated the presence of several common amino acids and an unidentified sulphur-containing compound."

Also, because of their fur, rats are assumed to have relatively high requirements of sulphur-containing amino acids (methionine and cysteine).

This can be explained by a high concentration of all essential amino acids, especially lysine, threonine, tryptophan, and the sulphur-containing amino acids.

Additionally, cysteine (or sulphur-containing amino acids), tyrosine (or aromatic amino acids), and arginine are required by infants and growing children.

Reflectins, a recently identified protein family that is enriched in aromatic and sulphur-containing amino acids, are used by certain cephalopods to manage and manipulate incident light in their environment.

Sulphur is important too, as some common amino acids also contain small amounts of this element, and virtually all natural proteins contain some of these sulphur-containing amino acids.

These are best known as eye pigments and comprise two groups of substances, the sulphur.free ommatins of low molecular weight and, the sulphur-containing ommins of high molecular weight.

The flavouring chemicals include "carbonyl compounds, alcohols, carboxylic acids and their esters, nitrogen- and sulphur-containing compounds, tannins and other polyphenolic compounds, terpenes, and oxygen-containing heterocyclic compounds" and esters of fatty acids.

Studies have established that the most active factors in garlic (including allistatin I and allistatin II) are sulphur-containing compounds which are effective agents against staphylococcus and Escherichia coli (E. coli), which are bacteria that can cause serious infections that can lead to death.

It is also a significant sulfur-containing impurity in synthesis gas.

These areas all burn sulfur-containing coal to generate heat and electricity.

Onion cells have sulfur-containing compounds that are released when you damage the cell wall.

The sulfur dioxide is derived from any sulfur-containing compounds in the fuels.

Researchers believe that allicin, a sulfur-containing compound in garlic, may have beneficial effects.

Historically, sulfur-containing compounds were the first materials used to dealkalize glass containers.

These enzymes are transferases, specifically the sulfotransferases, which transfer sulfur-containing groups.

Some of the main classes of sulfur-containing organic compounds include the following:

While sulfur-containing antibiotics save many lives, sulfur mustard is a deadly chemical warfare agent.

The other sulfur-containing amino acid, methionine, cannot form disulfide bonds.

Methionine levels also affect the amount of sulfur-containing compounds, such as glutathione, in the liver.

This enzyme belongs to the family of transferases, to be specific, the sulfotransferases, which transfer sulfur-containing groups.

This method is however is not selective and suffers from interferences with other sulfur-containing chemicals.

Fischer-Tropsch catalysts are sensitive to poisoning by sulfur-containing compounds.

Sulfur dioxide is the main byproduct produced when sulfur-containing fuels such as coal or oil are burned.

The problem for the clams is that they need to be near oxygen, but also near the sediments, the source of the sulfur-containing compounds.

Together with cysteine, methionine is one of two sulfur-containing proteinogenic amino acids.
