L-Histidine |
 |
|
Synonyms:L-Histidine hydrochloride Molecular Structure: Molecular Formula:C6H9N3O2.HCl Molecular Weight:191.62 CAS Registry Number:1007-42-7 Functions: L-Histidine is an essential amino acid that cannot be formed by other nutrients, and must be in the diet to be available to the body. Most often recognized as a precursor to the allergy symptom producing hormone histamine, both histidine and histamine have essential roles in the body beyond tormenting allergy sufferers. Histamine is well known for its role in stimulating the inflammatory response of skin and mucous membranes such as those found in the nose - this action is essential in the protection of these barriers during infection. Histamine also stimulates the secretion of the digestive enzyme gastrin. Without adequate histamine production healthy digestion can become impaired. Without adequate L-histidine stores, the body cannot maintain adequate histamine levels. Less well known is that L-histidine is required by the body to regulate and utilize essential trace minerals such as copper, zinc, iron, manganese and molybdenum

Cystine |
 |
|
Synonyms: L-Cystine CAS#: 56-89-3 Molecular Structure: Molecular Formula: C6H12N2O4S2 Molecular Weight: 240.3 Functional Use: Cystine is a crystalline, sulfur-containing amino acid, formed from two molecules of the amino acid cysteine. It can be converted to cysteine by reduction and was discovered in 1810 but was not recognized as a component of proteins until 1899, when it was isolated from animal horn – it is particularly abundant in skeletal and connective tissues, hair and digestive enzymes. L- Cystine helps strengthen the immune system, reduce damage from free-radicals, repair RNA-DNA in the cells and assimilation of vitamin B6. L-Cystine is closely related to the amino acid, L-Cysteine. L-Cystine aids in preventing the side effects of chemotherapy and radiation. It increases L-Glutathione levels in the lungs, liver, kidney and bone marrow. L-Cystine also has an anti-aging effect on the body which can reduce the accumulation of age spots.

Nitric oxide is involved in vasodilation (or simply put, dilation of the blood vessels); low levels have been associated with mental and physical fatigue and sexual disorders. L-Citrulline also promotes healthier skin and immune functions, and is part of the Urea Cycle — it assists in converting ammonia to urea in your liver, which offers protection against damage and helps keep your liver functioning properly.

Inulin and oligofructose can be used to increase the dietary fiber content of a wide variety of food products. Dietary fibers are essential in our daily food but our diets rarely contain enough of them. The average adult should consume about 25-30 grams a day. Few of us actually eat more than 15-20. Inulin can be added to foods to increase the dietary fiber content. Scientific studies have shown that inulin also stimulate the growth of beneficial bacteria in the large intestine, leading to healthier colonic microbiota. This so-called prebiotic effect improves the working of the intestine and ultimately the consumer's well-being Applications Inulin is widely used in various types of foods like confectionery, fruit preparations, milk desserts, yogurt and fresh cheese, baked goods, chocolate, ice cream and sauces. Inulin can also be used for the preparation of fructose syrups.
