Leucine Latest News

Researchers said that branched chain amino acids leucine acts like a protective shield and inhibits the premature degradation of outer mitochondrial membrane proteins.  

About Leucine

• Leucine is an essential amino acid.
• It belongs to the family of branched chain amino acids (BCAA) such as isoleucine and valine.
• These are needed for the growth and functioning of organs such as muscles, nervous system, the heart, and the brain.
• BCAAs are not made in the body and need to be supplied from our diet. Without them, the outer membrane of the mitochondrion cannot be properly constructed or maintained. 
• Functions
  • It is involved in muscle growth, tissue repair, and energy production. 
  • It acts like a protective shield and inhibits the premature degradation of outer mitochondrial membrane proteins.
  • This is done by leucine interacting with a protein called SEL1L, which has a role in recognising and pulling out damaged or misfolded proteins.

What are Amino Acids?

• Amino acids are molecules that combine to form proteins.
• Amino acids and proteins are the building blocks of life.
• There are 20 different amino acids.
• A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene.
• Some amino acids can be synthesized in the body, but others (essential amino acids) cannot and must be obtained from a person’s diet.
• The nine essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
