isoleucine

isoleucine

1 8.3
A part of protein in food that the body needs to build and repair tissues
  • noun
  • /ˌaɪsoʊˈluːsiːn/
  • Specialized
: isoleucina
  • BCAAs, or branched-chain amino acids, consist of three amino acids: leucine, isoleucine, and valine.
  • isoleucine and leucine
  • isoleucine and valine

I would say that we do not add leucine alone because leucine, isoleucine and valine go hand in hand.

Examples

  • Athletes often supplement their diets with isoleucine to help build muscle and recover from workouts.

  • In two families, the APP gene mutation was a base change leading to the substitution of valine with isoleucine at a residue in the transmembrane domain, two residues away from the C-terminus of the Beta/A4 sequence.

    Academic text (1992)

  • So the first example here we can consider the sky and isoleucine and valine.

  • And this is illustrated by actual data on isoleucine and leucine.

  • I would say that we do not add leucine alone because leucine, isoleucine and valine go hand in hand.

    Andrew Huberman

  • The branched-chain amino acids (BCAAs) leucine, isoleucine, and valine make up more than one third of muscle protein.

    Blog text (23)

  • The body cannot produce isoleucine, so it must be obtained from food sources.

  • Foods such as meat, fish, and legumes are good sources of isoleucine, which is vital for human nutrition.

Morphology

isoleucine = leucine (semi-transparent) = iso + leucine + iso

Morphologically clear as 'iso-' (denoting an isomeric form) + 'leucine', but understanding that it denotes a specific isomer requires specialized chemistry knowledge so it is not fully transparent to an average B1 learner.

Etymology

Isoleucine comes from iso- meaning 'equal' or 'same' and leucine from a word meaning 'white'. Chemists named it because it has the same parts as leucine but in a different shape, so the name helps you remember that isoleucine is a 'same' but different form of an important amino acid your body needs.
