Amino acids are the basic units of proteins and are essential organic compounds in life. There are about 500 different amino acids in nature, but among the amino acids that make up the proteins of living organisms, 20 are standard amino acids, which are connected in different sequences to form proteinaceous proteins that perform various physiological functions in living organisms.

Japanese big-eared white rabbits have high fertility, strong physique, and are more resistant to rough feeding, cold-resistant, strong adaptability, large body size, rapid growth and development, and adult weight of 3.5-4 kg. All parts of China are kept. Japanese big-eared white rabbits have large ears, fine auricular roots, and pointed ears, which resemble willow leaves. They are erected backwards with thin ears and vascular network. They are suitable for injection and blood collection. They are ideal for experimental rabbits. Amount of breadth, surface abundance, coat white, thick and soft, red eyes, large area of ​​skin, good texture, thick neck, female rabbit has meat under the neck. High fertility, 4-5 nests per year, 8-10 litters per litter, up to 12. The average weight of newborn rabbits is 60 grams, and the female rabbits have a large amount of milk and good maternal properties. The growth was rapid, with an average weight of 1.4 kilograms at 2 months, 3 kilograms at 4 months, 4 kilograms at 7 months, and an average weight of 4 kilograms per adult. The meat quality was better; the adult body was 44.5 centimeters long and the chest circumference was 33.5 centimeters.
After introduction in our country, pure-complex rabbits are used for testing; meat rabbits used for cross-breeding production are also effective, but better feeding and management conditions need to be given, otherwise the effect is not good.
Amino acids can be divided into the following categories according to their location and function in proteins
1.Essential amino acids
9 amino acids that the body cannot synthesize by itself or the synthesis speed cannot meet the needs, and must be ingest through food, including lysine, tryptophan, phenylalanine, methionine, threonine, isoleucine, leucine, valine and histidine (infants also need histidine).
2.Non-essential amino acids
The human body can synthesize by itself and does not need to obtain directly from food, including glutamic acid, aspartate, alanine, serine, glycine, proline, cysteine, etc.
3.Conditional essential amino acids
Under specific conditions (such as disease, stress), the human body's synthetic ability is reduced, and additional supplements are needed, such as arginine, glutamine, etc.
Amino acids are also widely used in the field of skin care, as skin care ingredients, they mainly have the following effects
1.Moisturizing
Some amino acids such as glycine, alanine, etc. have good hygroscopic properties, which can help the skin retain moisture and enhance its moisturizing ability.
2.Repair
Such as arginine, glutamic acid, etc. participate in the repair and regeneration process of skin cells, promoting wound healing.
3.Anti-aging
Certain amino acids have antioxidant effects that can help fight free radical damage and slow down skin aging.
4.Cleansing
Amino acid surfactants, such as sodium lauryl sarcosine, are commonly used in cleansing products for sensitive skin due to their mild, non-irritating properties.
Therefore, amino acids are not only essential for human health, but also play an important role in beauty and skin care products.
Japanese white rabbit
Native to Japan. It is said that it was produced by crossbreeding of white rabbits and Japanese rabbits of Chinese national rabbits.
