Description：

1. Amino acids are organic compounds containing alkaline amino groups and acidic carboxyl groups. According to the number of amino groups and carboxyl groups contained in amino acids, amino acids are divided into neutral amino acids, acidic amino acids and basic amino acids.

2. According to the polarity classification of amino acids, amino acids can be divided into non-polar amino acids and polar amino acids. According to the chemical structure, amino acids can be divided into aliphatic amino acids, aromatic amino acids, heterocyclic amino acids and heterocyclic subamino acids.

Usage:

1. In the cosmetics or cleaning industry, amino acid additives usually have a moisturizing effect. Amino acid surfactants are less irritating to the skin because of their weak acidity. Some amino acid additives also have anti-allergic, antioxidant, and anti-aging effects.

2. In the pharmaceutical industry, amino acids can be used as therapeutic drugs, as well as to prepare compound amino acid infusions, and for the synthesis of polypeptide drugs. Amino acid APIs and their derivatives play an important role in supplementing human nutrition, treating digestive tract diseases, liver diseases, nervous system diseases, and tumors.

3. In the feed industry, amino acids, as an essential type of additive, can balance the amino acid content in feed, improve animal health, reduce environmental pollution and feed costs, all of which bring great benefits to breeding production.
