Isocolumbin has anti-inflammatory, and antimicrobial activities.

L-Tryptophan-15N2是标记有15N的L-Tryptophan (T0439)。L-Tryptophan (Tryptophan)是一种必需氨基酸，并且是血清素、褪黑素和维生素B3的前体。

Emtricitabine-15N,D2是一种具有 15N 和氘代标记的 Emtricitabine。Emtricitabine (T6214)作为一种核苷逆转录酶抑制剂 (NRTI)，它在 PBMC 细胞中的 EC50 为 0.01 μM。此化合物可用于研究 HIV 感染。

NADP+ is the oxidized form of the electron donor nicotinamide adenine dinucleotide phosphate . It serves as a cofactor in various biological reactions. In addition, the balance between these reduced and oxidized forms plays key roles in diverse cellular functions, including cell survival, the maintenance of redox status, and intracellular signaling. For example, binding of NADP+ to β-subunits of Kv channels activates ion transport, whereas NADPH stabilizes channel inactivation. NADP+ is biosynthesized from NAD+ by NAD kinase, with ATP as the phosphoryl donor.

Argininic acid is an α-amino acid used in the biosynthesis of proteins.

Cyclohexanoyl coenzyme A (CHCoA) is an acyl CoA that contains a cyclohexane group. It is the activated form of cyclohexane carboxylic acid (CHC) in R. palustris. CHC is converted to CHCoA by a succinyl-CoA CHC CoA transferase, and CHCoA is then degraded by a dehydrogenase. CHCoA is converted to hippuric acid in submitochondrial fractions isolated from guinea pig liver.

L-Leucine-D7是L-Leucine的氘代变体。L-Leucine (T3O2749)作为一种必需的支链氨基酸 (BCAA)，能够激活mTOR信号通路。

Amidases属于腈水解酶超家族，专门催化酰胺水解成羧酸和氨。该酶含有一个约130个氨基酸组成的保守序列，即AS序列，在关键代谢过程中扮演重要角色。
