The phrase "branched chain" is correct and usable in written English.
It refers to a chain-like structure that has multiple branches branching off of it. This term is commonly used in chemistry or biology to describe certain types of molecules or molecules with a branching structure. Example: "The protein is composed of a branched chain of amino acids, giving it a unique shape and function."
Branched chain fatty acids are built from branched chain acyl-CoA primers, which in turn are derived from the degradation of branched chain amino acids [ 49].
Branched chain aminotransferases (BCATs) catalyze transamination of the branched chain amino acids (BCATs) leucine, isoleucine, and valine.
Lacking PARP2-dependent branched chain may also impair the recruitments of other branch chain readers.
Although PARP1 is also able to catalyze the branched chain, we found that the level of branched chain was relatively low in PARP2-deficient cells.
Collectively, the NTR is required for the PARP2-dependent PARylation, especially the branched chain formation.
The results suggest that PARP1 is also able to catalyze branched chain, but at lower rate30.
Therefore, the requirement for branched-chain amino acid transport was investigated in other legume-rhizobia interactions.
Branched-chain VFAs are derived from branched-chain amino acids (e.g. leucine, valine and isoleucine) and the ratio of straight-chain to branched-chain VFA is an indicator of amino acid fermentation (Hernandez-Sanabria et al., 2010).
In astrocytes, branched-chain transaminase functions in the glutamate cycle by transferring amines from branched-chain amino acids to αKG to produce glutamate and the associated branched-chain ketoacid (Yudkoff et al., 2005) (Fig. 10).
MSUD results in accumulation of branched-chain ketoacids and branched-chain amino acids measured in blood, urine and cerebrospinal fluid (Mackenzie and Woolf, 1959).
This pathway allows usage of branched-chain amino acids as nitrogen sources and conversion of branched-chain amino acids into the corresponding free acids: isovalerate, isobutyrate, and methylbutyrate.
