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.

CAS#: 372-75-8
Molecular Structure:
Molecular Formula: C6H13N3O3
Molecular Weight: 175.19
Functional Use：
L Citrulline is an amino acid that converts to L-arginine and then nitric oxide in your bloodstream. 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.

Lecithin can be totally metabolized by humans, so is well tolerated by humans and non-toxic when ingested; some emulsifiers can only be excreted via the kidneys.
Lecithin is used for applications in human food, animal feed, pharmaceutical, paint, and other industrial applications.
In the pharmaceutical industry it acts as a wetting, stabilizing agent and a chlorine enrichment carrier, helps in emulsifications and encapsulation, and is a good dispersing agent. It can be used in manufacture of intravenous fat infusions and for therapeutic use.
In animal feed it enriches fat & protein and improves pelletization.

Spec: 85, 90, 95 ,98% Min.for the food and drug grade, 50% Min. feed grade
Appearance: White creamy powder
Inulins are a group of naturally occurring fructo-oligosaccharides produced by chicory plant
Typical function:
1.Soluble dietary fiber
2.Low carorie bulking agent
3.Promote Calcium absorption and so enhance bone density
4.Prebiotic effect, beneficial bacteria promoter
5.Replace sugar and fat while improving taste and mouthfeel.
6.Pure natural, safe
Dogestive .
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.
