Toopcham et al  reported that the tripeptide Met-CysSer, containing the branched-chain amino acid Met at the Nterminus, exhibited higher ACE inhibitory activity than that of tetrapeptide Ala-Leu-Ser-Cys.
(3) Kim and Lee (2) discussed two studies that reported that ingestion of taurine alone or in combination with branched-chain amino acid (BCCA) was able to reduce DOMS following intense exercise, though it wasn't clear why.
 MSUD is a disorder of branched-chain amino acid catabolism, caused by a deficiency in the branched-chain [alpha]-keto acid dehydrogenase complex, which is responsible for the decarboxylation of the branched-chain amino acids (BCAA), leucine, isoleucine, and valine (Fig.
Pathway enrichment and topology analysis identified enrichment in purine, pyrimidine, inositol phosphate, and branched-chain amino acid metabolism in addition to lysine degradation in both BMM and MDM.

Formerly, studies have shown that a drop in plasma branched-chain amino acid levels in cases with urea-cycle metabolism disorders can be obtained with sodium phenylacetate/benzoate or sodium phenylbutyrate (NaPB) treatments [4, 5].
