A branched-chain amino acid (BCAA) is an amino acid having an aliphatic side-chain with a branch (a central carbon atom bound to three or more carbon atoms). Among the proteinogenic amino acids, there are three BCAAs: leucine, isoleucine, and valine. [1] Non-proteinogenic BCAAs include 2-aminoisobutyric acid and alloisoleucine. Leucine ...
2-, alpha-, or α-amino acids [21] have the generic formula H 2 NCHRCOOH in most cases, [b] where R is an organic substituent known as a "side chain". [22] Of the many hundreds of described amino acids, 22 are proteinogenic ("protein-building").
The following is a list of straight-chain alkanes, the total number of isomers of each (including branched chains), and their common names, sorted by number of carbon atoms. [ 1 ] [ 2 ] Number of C atoms
Protein sequence is typically notated as a string of letters, listing the amino acids starting at the amino-terminal end through to the carboxyl-terminal end. Either a three letter code or single letter code can be used to represent the 22 naturally encoded amino acids, as well as mixtures or ambiguous amino acids (similar to nucleic acid ...

Succinyl CoA can be formed from methylmalonyl CoA through the utilization of deoxyadenosyl-B 12 (deoxyadenosylcobalamin) by the enzyme methylmalonyl-CoA mutase.This reaction, which requires vitamin B 12 as a cofactor, is important in the catabolism of some branched-chain amino acids as well as odd-chain fatty acids.
The essential amino acids are histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine (i.e. H, I, L, K, M, F, T, W, V). [3] The proteinogenic amino acids have been found to be related to the set of amino acids that can be recognized by ribozyme autoaminoacylation systems. [4]
Branched pathways have unique control properties compared to simple linear chain or cyclic pathways. These properties can be investigated using metabolic control analysis . The fluxes can be controlled by enzyme concentrations e 1 {\displaystyle e_{1}} , e 2 {\displaystyle e_{2}} , and e 3 {\displaystyle e_{3}} respectively, described by the ...
