Boc-(R)-2-aMino-5-Methylhexanoic acid, also known as Boc-protected L-isoleucine, is a compound that belongs to the family of amino acids. It is a derivative of the essential amino acid isoleucine, which is important for protein synthesis and muscle metabolism in the human body. The "Boc" in the name refers to the tert-butyloxycarbonyl protecting group, which is commonly used in organic synthesis to protect specific functional groups during chemical reactions. Boc-(R)-2-aMino-5-Methylhexanoic acid is often used in peptide and protein synthesis as a key building block, and its Boc-protected form allows for selective deprotection and manipulation of the amino acid during chemical reactions. Boc-(R)-2-aMino-5-Methylhexanoic acid plays a crucial role in the production of peptides and proteins for various research and pharmaceutical applications.
