Protein is regarded as the material base of life and it has a close relationship with the formation, existence and extinction of life. Deficiency of protein will result in a poor health, weaken immunity, delayed growth or anemia; in some serious cases, it will cause edematization even threat to life. Protein accounts for 16.3% of human weight, that is to say there is about 9 kilograms protein for a 55kg adult. There are different types of proteins in human body with different properties and functions which undergo continuous metabolism and updates in the body. 

Protein is composed of polypeptide and basic unit of polypeptide is amino acid; therefore protein is a kind of organic compound consists of different amino acids. The different marshalling sequence of amino acid will lead to varieties of protein types and different proteins have different physiological functions which involve in the metabolism of life. Deficiency of any of essential amino-acid will cause abnormity in physiological function thus affect the normal operation of antibody metabolism and result in different diseases. Lacking of some non-essential amino acids may also cause disorders of antibody metabolism. 

Proteins in food that human takes are disintegrated to amino acids under the action of digestive enzymes, and these amino acids will reorder in a certain sequence to combine to new proteins after absorbed by human body; meanwhile, old proteins undergo continuous metabolism and decomposition which make themselves balanced in the body. Therefore quality & quantity of protein and ratio of different amino acids in human body influences the quality of protein synthesis; and quality and quantity of protein in daily food play a very important role in deciding how long the people could live. Besides synthesizing to new protein, amino acids also play a very important role in some physiological function independently.

There are more than 20 kinds of amino acids that can be tested in pine pollen, including 8 essential amino acids which body can’t synthesize on their own and the ratio is very close to criterion that made by WHO(World Health Organization) and FAO(Food and Agriculture Organization). Compared with other bee source pollens, amino acids contents in pine pollen are distinctly higher.

Direct physiological actions of 8 human body essential amino acids in pine pollen

Name of amino acid

Physiological actions

phenylalanine

Participate in and eliminate the damage/wastage of kidney and bladder function

isoleucine

Participate in adjustment and metabolism of thymus gland, spleen and pituitary gland, pituitary gland acts as the chief commander to work on thyroid gland and sexual gland.

lysine

As a component of liver and gallbladder; promote brain development and fat metabolism; adjust function of pineal gland, mammary gland, corpus luteum and ovary; prevent degeneration of cells.

tryptophan

Promote production of gastric juice and pancreatic juice.
