Yes they do. proteins are macromolecules that are made up of amino acids connected with peptide linkage. Sulfur containing amino acids such as cysteine, methionine are also can be present in proteins. they are involved in the formation of disulfide linkage in the protein molecule.

How do plants use sulphur?

Plants cannot make protein from pure carbohydrate, because proteins contain nitrogen and sometimes sulphur. They get the nitrogen which they need from the nitrates in the soil. They get the sulphur from sulphates in the soil.


What are Large molecules made of carbon and hydrogen atoms?

Proteins are the large molecules that are made up of Carbon, Hydrogen, Oxygen and sulphur. Carbon, Hydrogen and oxygen are chiefly present in all the biomolecules. But the proteins contain sulphur as their one of the components, as DNA have Phosphorus as one of their important component. Two amino acids, Methionine and Cysteine, contain sulphur in their side chain. When these amino acids are incorporated in the proteins, sulphur is added to the proteins. Sulphur present in cysteine, as a thiol group, play a crucial role in the stability of the proteins as they form disulphide bonds. Apart from that, two polysaccharides also contain sulphur. Chondroitin -4- Sulphate is a polymer of repeating unit of Glucuronic acid and NAcetylGalactosamine that is sulphated at the fourth carbon. The other polysaccharide is Kertan Sulphate. It has repeating units of Galactose and NAcetylGlucosamine sulphated at 6th carbon.

What are the elements found in proteins butb not in carbohydrates and fats?

Nitrogen and sulphur, proteins are made of amino acids which contain an amine group NH, a carboxyl group COOH and an R group. The R group is a side chain, which is different in each of the 20 amino acids, which in methionine and cysteine contains a sulphur group. Carbohydrates contain carbon and hydrogen. Fats also contain carbon and hydrogen in the form of triglyceride and fatty acids.
