l-biotin

L-Biotin, or simply biotin, is a water-soluble vitamin crucial for carboxylation reactions in various enzymes. It plays a significant role in the synthesis of fatty acids and the metabolism of amino acids [1].

Biotin-hexanamide-(L-Thyroxine) is a biotinylated derivative of L-Thyroxine (Levothyroxine; T4), used as a synthetic hormone in hypothyroidism research [1].

L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

Biocytin is a classical neuroanatomical tracer commonly used to map brain connectivity. Biocytin is a conjugate of D-biotin and L-lysine, where the carboxylate of D-biotin is coupled with the ϵ-amine of L-lysine via a secondary amide bond.

L-Cysteine-d3 is a deuterated compound of L-Cysteine. L-Cysteine has a CAS number of 52-90-4. L-Cysteine is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

3-Hydroxyisovalerylcarnitine (Standard) is an acylcarnitine involved in fatty acid metabolism, and is a biomarker of biotin deficiency, with concentrations that are significantly elevated in biotin deficiency. As a standard, 3-Hydroxyisovalerylcarnitine (Standard) can be used for quantitative analysis, study of metabolic pathways and diagnosis of related diseases.

L-Cysteine (Standard) is the standard substance of L-Cysteine, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. L-Cysteine (L-(+)-Cysteine) is a non-essential sulfur-containing amino acid in humans. L-Cysteine is important for protein synthesis, detoxification, and diverse metabolic functions. Found in beta-keratin, the main protein in nails, skin, and hair, L-Cysteine is important in collagen production, as well as skin elasticity and texture. Also required in the manufacture of amino acid taurine, L-Cysteine is a component of the antioxidant glutathione, and plays a role in the metabolism of essential biochemicals such as coenzyme A, heparin, and biotin.

N-Biotinyl-L-cysteine is a biotinylated biochemical reagent utilized in the detection of avidin and biotin through competitive binding assays.
