Proteins are the building blocks of life. The body needs protein to repair and maintain itself. The basic structure of protein is a chain of amino acids. Every cell in the human body contains protein. It is a major part of the skin, muscles, organs, and glands. Protein is also found in all body fluids, except bile and urine. You need protein in your diet to help your body repair cells and make new ones. Protein is also important for growth and development during childhood, adolescence, and pregnancy.
When proteins are digested, amino acids are left. The human body needs a number of amino acids to break down food. Amino acids need to be eaten in large enough amounts for optimal health. Amino acids are found in animal sources such as meats, milk, fish, and eggs, as well as in plant sources such as soy, beans, legumes, nut butters, and some grains (such as wheat germ). You do not need to eat animal products to get all the protein you need in your diet. Essential amino acids cannot be made by the body, and must be supplied by food. They do not need to be eaten at one meal. The balance over the whole day is more important.

As your post says here, the protein is the building blocks of life and the amino acid(http://www.creative-proteomics.com/products/amino-acid_81.htm) is the basic substance of protein. the amino acid can be very useful for our body. thanks for sharing this.
回复删除Protein in diet is extremely important because it is crucial for complementing necessary energy that physical body demands. Maybe acetyl tetrapeptide-9 can be sort of helpful as well.
