High Purity L-Lysine CAS 56-87-1 Amino Acid Powder Lysine CAS 56-87-1

L-Lysine is an essential amino acid, meaning it cannot be synthesized by the human body and must be obtained through the diet or supplementation. It is a crucial building block for protein synthesis and plays various roles in physiological processes.

The specifications of L-Lysine can vary depending on the specific grade and application. Here are some general specifications:

  • Chemical formula: C6H14N2O2
  • Molecular weight: 146.19 g/mol
  • Appearance: White crystalline powder
  • Purity: Typically, not less than 98% or higher (depending on the grade)
  • Solubility: Soluble in water
  • Melting point: Approximately 224-225 °C
  • Optical rotation: +20.4° to +21.4° (specific rotation)




  1. Essential amino acid: L-Lysine is an essential amino acid, meaning it is necessary for proper growth, development, and overall health. It must be obtained through the diet or supplementation since the body cannot produce it in sufficient quantities.

  2. Protein synthesis: L-Lysine plays a crucial role in protein synthesis, serving as a building block for the formation of various proteins in the body. This is important for tissue repair, growth, and maintenance.

  3. Collagen synthesis: L-Lysine is involved in collagen synthesis, a vital component of connective tissues, skin, and bones. It supports the production of collagen, which contributes to the strength and elasticity of these structures.

  4. Immunomodulatory effects: L-Lysine has been studied for its potential immunomodulatory effects, including its role in enhancing immune function and reducing the severity and recurrence of certain viral infections.

  5. Generally recognized as safe: L-Lysine is generally recognized as safe (GRAS) for its intended uses in food, dietary supplements, and personal care products. However, it's important to follow recommended dosages and guidelines.

it is a kind of amino Acid, which can't be compounded automatically in the animal body. It plays an importance role is metabolism. The growing animals are keen to lack of lysine. The faster animals grow, the more lysine animal need. So it is called growing animoacid.

Nutritional Supplement:

Animal Feed: Added to animal feed to enhance the growth and health of livestock, poultry, and fish.
Human Dietary Supplements: Used to support protein synthesis, tissue repair, and immune function in humans.
Pharmaceutical Applications:

Antiviral Agent: Studied for its potential antiviral effects, particularly against herpes simplex virus (HSV) infections.
Wound Healing: Plays a role in collagen synthesis, essential for wound healing. Used in topical formulations or wound dressings.
Cosmetic and Personal Care Products:

Included in various cosmetic and personal care products like lotions, creams, shampoos, and conditioners due to its beneficial effects on skin hydration, collagen production, and hair strength.
