Questions about Methylcobalamin, min. 98,5 %, for biochemistry, 25 mg, glass
What is this article?
Methylcobalamin, min. 98,5 %, for biochemistry, 25 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Coenzymes, nucleotides & vitamins, inside Biochemicals & reagents, in Microbiology lab supplies.
Coenzymes, nucleotides and vitamins are the small molecules enzymes and cells consume: NAD, ATP, a vitamin cofactor. Purity, salt form and hydration are the specification, and many are unstable in solution or in the light. The lot is stored as the label says, often cold.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
