isoleucine
A student studies the molecular structure of isoleucine in a biochemistry textbook.
Noun An essential amino acid that is one of the building blocks of proteins. It is classified as essential because the human body cannot synthesize it, so it must be obtained from the diet. Isoleucine is isomeric with leucine, meaning it has the same molecular formula but a different structural arrangement.
Isoleucine is used primarily in scientific, nutritional, and biochemical contexts to discuss protein composition, dietary requirements, and metabolic processes. * A diet lacking isoleucine can lead to protein deficiency. * This enzyme is responsible for breaking down isoleucine. * The nutritional label shows the isoleucine content per serving.
- Branched-Chain Amino Acid (BCAA): Isoleucine is one of the three BCAAs (alongside leucine and valine), which are metabolized in muscle tissue and are often discussed in sports nutrition.
- Athletes may supplement with BCAAs like isoleucine to support muscle recovery.
- Metabolic Pathways: In biochemistry, isoleucine is studied for its role in specific metabolic cycles and its conversion into other compounds.
- The study focused on the catabolism of isoleucine.
- Ile: The standard three-letter abbreviation for isoleucine used in biochemistry and molecular biology to denote it in protein sequences.
- The peptide sequence reads: Gly-Ile-Val.
- I: The single-letter code for isoleucine used in bioinformatics and genetic coding.
- The mutation changed the codon from AUU to AUC, both of which code for I.
This word has a single, specific meaning in biochemistry and nutrition. It does not have other common definitions.
- Essential amino acid: This is its category. (Note: "Leucine" is not a synonym; it is a different, though structurally similar, essential amino acid.)
