DL-methionine with the CAS number 59 - 51 - 8 is a high - quality product that stands out in the market due to its excellent price - to - quality ratio. It is an essential amino acid, which means it cannot be synthesized by the body and must be obtained through diet or supplements.
Chemically, DL - methionine is a racemic mixture of D - and L - methionine. It has a molecular formula of C₅H₁₁NO₂S and a molecular weight of approximately 149.21 g/mol. The product typically comes in a white, crystalline powder form, which is odorless or has a slight characteristic odor. It is soluble in water, with solubility characteristics that make it suitable for various applications.
1. Animal Feed: DL - methionine is widely used in animal feed. In poultry and swine production, it is a key ingredient to meet the animals' amino acid requirements. It helps in promoting growth, improving feed efficiency, and enhancing the quality of meat and eggs. For example, in chicken farms, adding an appropriate amount of DL - methionine to the feed can lead to faster growth of chickens and better - quality eggs with stronger shells.
2. Human Nutrition: In the field of human nutrition, it can be used as a dietary supplement, especially for vegetarians and vegans who may have a deficiency in essential amino acids. It also plays a role in various metabolic processes in the human body, such as the synthesis of proteins, the production of antioxidants, and the metabolism of fats.
3. Pharmaceutical Industry: Due to its important physiological functions, DL - methionine is used in the production of some pharmaceutical products. It can be an ingredient in drugs for treating liver diseases, as it helps in the detoxification process in the liver.
1. In Animal Feed: The recommended dosage in animal feed varies depending on the type of animal, its age, and growth stage. Generally, for poultry, the addition rate may range from 0.1% - 0.5% of the total feed. For swine, it may be around 0.1% - 0.3%. It is important to mix the DL - methionine evenly in the feed to ensure that each animal gets the proper amount.
2. As a Dietary Supplement for Humans: When used as a dietary supplement, it should be taken according to the instructions on the product label. Usually, it is recommended to take it with meals to enhance its absorption. It is advisable to consult a healthcare professional before starting any new dietary supplement.
3. In the Pharmaceutical Industry: The usage in pharmaceutical production is strictly regulated by relevant standards and procedures. Pharmaceutical manufacturers should follow the specific formulas and production processes to ensure the quality and effectiveness of the final products.
Case 1: A large - scale poultry farm in the United States. Before using DL - methionine in the feed, the average weight of chickens at the age of 42 days was 1.8 kg, and the feed - to - meat ratio was 2.2:1. After adding 0.3% DL - methionine to the feed, the average weight of chickens at the same age increased to 2 kg, and the feed - to - meat ratio decreased to 2:1. This not only increased the productivity but also reduced the cost of feed.
Case 2: A group of vegetarians in Europe participated in a six - month dietary supplement experiment. Half of them took DL - methionine supplements daily, while the other half did not. After six months, the group taking the supplements showed significant improvement in their overall health, including better skin condition, increased energy levels, and improved immune function.
