Valine
A branched-chain essential amino acid with a glucogenic carbon route.
Valine is incorporated into proteins and its carbon portion can enter metabolism as succinyl-CoA after breakdown.
A glucogenic carbon route
Glucogenic means that valine’s carbon portion can form intermediates used in pathways that make glucose; it does not describe an immediate change in blood glucose.

Valine is used to build Protein
Valine is one of the amino acids used to assemble proteins.
Worth knowing
It is required from dietary protein. Humans cannot synthesise enough valine and obtain it from dietary protein.
A closer look
Its route differs from other branched-chain amino acids
Leucine, isoleucine and valine share a branched structure but have different carbon-skeleton fates.
Its side chain is hydrophobic
Valine’s branched hydrocarbon side chain commonly contributes to the less polar interior of a folded protein.
