Products Pure sulfur is available in pharmacies and drugstores. It is found in creams, shampoos and sulfur baths, among other products. Structure and properties The pharmacopoeia defines sulfur for external use (S, Mr = 32.07 g/mol) as a yellow powder that is practically insoluble in water. Sulfur melts at about 119°C to form a red … Sulfur
Products Sulfur dioxide is commercially available as a liquefied gas in compressed gas cylinders. Structure and properties Sulfur dioxide (SO2, 64.1 g/mol) exists as a colorless gas with a characteristic pungent and irritating sulfur odor that is soluble in water. The boiling point is -10°C. Sulfur dioxide is not combustible and is heavier than air. … Sulfur Dioxide
Cysteine, along with methionine, is a sulfur-containing amino acid. It is jointly responsible for the formation of the secondary, tertiary and quaternary structure of proteins. A deficiency of cysteine leads, among other things, to a weakness of the immune system. What is cysteine? Cysteine is a sulfur-containing amino acid with a thiol group (-SH). It … Cysteine: Function & Diseases
Peroxidases represent enzymes that break down hydrogen peroxide or organic peroxides in any organism. Peroxides are potent cytotoxins produced by numerous biochemical oxidation reactions. Thus, peroxidases are among the most important antioxidants. What are peroxidases? Peroxidases are enzymes that, in most cases, break down toxic hydrogen peroxide. However, organic peroxides are also reduced by these … Peroxidases: Function & Diseases
Keratins are special substances. They are found in human and also in animal organisms. The name “keratin” comes from the Greek and means “horn”. Therefore, the amino acids important for the body are also called horn cells. What are keratins? The umbrella term “keratins” covers various hydrophobic fibrous proteins that are the main component of … Keratins: Function & Diseases
Glutathione (TSH) is a tripeptide consisting of the three amino acids cysteine, glycine, and glutamic acid. Glutathione is considered one of the most important antioxidants in the human body. What is glutathione? Glutathione is also known as γ-L-glutamyl-L-cysteinylglycine. It is a sulfur-containing tripeptide, so it belongs to the group of proteins. Chemically, glutathione is not … Glutathione: Function & Diseases
Liver enzymes are enzymes typically found in liver cells (hepatocytes). In clinical parlance, they are often called liver enzymes. An increase in certain enzymes is an indication of liver damage, whereas other enzymes occur at lower levels in liver disease. What are liver enzymes? In liver disease, liver enzymes often provide important clues as to … Liver Enzymes: Function & Diseases
Our eyebrows are far more than just a genetically manifested component of human facial hair. They fulfill essential protective functions, are important mimic link in non-verbal communication and at the same time decorative “accessories”. No matter how diverse they may be in shape, styling and color – whether soft blond, narrow and arched or dark, … Eyebrows: Structure, Function & Diseases
As an enzyme of the pancreas, trypsin is responsible for the further breakdown of food proteins. It exerts its effect in the highly alkaline range. Trypsin deficiency leads to protein deficiency in the body due to impaired protein breakdown. What is trypsin? Trypsin represents a protease that continues the digestion of proteins in the alkaline … Trypsin: Function & Diseases
Trypsinogen is a zymogen or a proenzyme. Proenzymes are inactive precursors of enzymes. Trypsinogen is the inactive precursor of the digestive enzyme trypsin. What is trypsinogen? Trypsinogen is a so-called proenzyme. A proenzyme is a precursor of an enzyme. However, this precursor is inactive and must first be activated. Activation is carried out by proteases, … Trypsinogen: Function & Diseases
The biocatalyst sulfite oxidase causes the conversion of toxic sulfur compounds from the breakdown of amino acids into nontoxic sulfates. It is essential for life and is therefore found in all organisms. If its function is disturbed by a genetic defect, sulfite oxidase deficiency occurs. Even in otherwise healthy patients, too much sulfite in the … Sulfite Oxidase: Function & Diseases
Amino acids are the basic substances of proteins and there are 20 different amino acids from which the body can form many different proteins among other substances. The 20 amino acids can be divided into two groups, the essential and the non-essential amino acids. There are eight essential amino acids, isoleucine, leucine, lysine, methionine, phenylalanine, … Amino acids list
