The Chemistry of Protein
Protein consists of carbon, hydrogen, oxygen, and nitrogen. The addition of nitrogen provides protein its distinctive distinction from carbohydrate and fats, together with establishing the signature identify, amino acid. Very like easy sugars, which hyperlink collectively to kind a posh carbohydrate (see What Is a Carbohydrate?), amino acids are the constructing blocks for the extra sophisticated protein molecule.
Amino Acids: The Constructing Blocks of Protein
There are a complete of 20 totally different amino acids, and relying upon the sequence wherein they seem, a selected job or perform is carried out in your physique. Consider amino acids as just like the alphabet—26 letters that may be organized in 1,000,000 other ways. These organized letters create phrases, which then translate into a complete language. The association of amino acids is your physique’s “protein language,” which dictates the precise duties that should be carried out. Subsequently, proteins that make up your enzymes may have one sequence, whereas those who kind your muscle mass may have a very totally different one.
Your Bod: The Amino Acid Recycling Bin
Your physique frequently will get the amino acids it wants from its personal amino-acid pool and from a food regimen that meets your each day protein necessities. After you eat a meals that accommodates protein, your physique goes to work, breaking it down into the varied amino acids. (Completely different meals yield totally different amino acids.) When the protein is totally dissected, your physique absorbs the amino acids (ensuing out of your digested meals) and rebuilds them into the sequence that you simply want for a selected physique job. Your physique is type of like a recycling bin.
Let’s take this amino acid speak a bit additional. Out of 20 amino acids, 11 can truly be manufactured inside your physique. Nonetheless, which means 9 can’t be manufactured. You can not perform with out every amino acid. It’s “essential” that you simply get these 9 from exterior meals sources. Subsequently, they’re appropriately referred to as important amino acids.
