Definition of Amino Acid
Amino acid is a simple organic compound that contains a carboxyl (—COOH) and an amino (—NH2) group.
What are Amino Acids?
Amino acids are organic compounds containing carboxyl (—COOH) and amino (—NH2) functional group with side chain, this side chain is specific to amino acid. Carbon, Hydrogen, Oxygen and Nitrogen are some important element which present in amino acids. Some other elements may also present in side chain of some amino acids.
Importance of Amino Acids
As we all know that our body contains large amount of proteins also these proteins play important role in biological processes happening within human body. Amino acids are building blocks of these proteins means proteins contain amino acids.
Amino acids play key role in many body functions like cell structure, storage and transport of nutrients, proper functioning of organs, proper functioning of glands, proper functioning of arteries, proper functioning of tendons, healing of wounds, repairing tissues, removal of metabolic waste etc.
There are so many amino acids present in nature but human gene codes only 20 amino acids.
Areas of use of Amino Acids
Supply of amino acids to the body provides repair treatment means nourish human skin, nails and hair result in delay aging process naturally. Supply of amino acids strengthens connective tissue to keep our skin smooth, shine, glowing and elastic. Creatine play very important role to keep skin healthy and this creatine is made up of amino acids like Arginine and Methionine. Glutamine amino acid is responsible to regulate acid-base balance as a result it supports healthy skin. Carnitine is a di-peptide containing two essential amino acids lysine and Methionine… read more at https://chemistrynotesinfo.blogspot.com/2016/11/amino-acids.html
