As a key player in cellular energy production, red blood cell formation, and methylation pathways, B12 provides the stable metabolic foundation that allows researchers to accurately assess peptide effects without confounding variables. The compound is a highly complex essential vitamin of the B-complex family and is the most common and chemically stable vitamer, as it is the easiest to crystallize and purify after bacterial fermentation. Vitamin B12 is synthesized almost exclusively by bacteria and is found in dietary sources such as fish, meat, liver, and dairy products. It is used as a drug to correct vitamin B12 deficiency and to treat pernicious anemia.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"peptide-details\"\u003e\n\u003csummary\u003eMechanism of Action\u003c\/summary\u003e\n\u003cdiv class=\"peptide-content\"\u003e\n\u003cp\u003eVitamin B12 exerts its effects as an essential cofactor for two key enzymes in human metabolism: methionine synthase and L-methylmalonyl-CoA mutase. Methionine synthase catalyzes the conversion of homocysteine to methionine, a critical step in the synthesis of methionine and the regulation of homocysteine levels. L-methylmalonyl-CoA mutase is involved in the conversion of methylmalonyl-CoA to succinyl-CoA, linking lipid and carbohydrate metabolism. In the body, cyanocobalamin is converted into its bioactive coenzyme forms—methylcobalamin and cobamamide (adenosylcobalamin)—which serve as essential cofactors for these metabolic processes. Vitamin B12 is also required for the normal development of red blood cells and plays a critical role in maintaining the methylation cycle, which is fundamental to numerous cellular processes including DNA synthesis, neurotransmitter production, and detoxification pathways.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"peptide-details\"\u003e\n\u003csummary\u003eResearch Applications\u003c\/summary\u003e\n\u003cdiv class=\"peptide-content\"\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeptide Research and Metabolic Support:\u003c\/strong\u003e Employed as a foundational cofactor in peptide studies to maintain metabolic homeostasis and ensure accurate assessment of peptide effects without confounding variables.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNutritional and Metabolic Research:\u003c\/strong\u003e Investigated as an essential cofactor for studying one-carbon metabolism, homocysteine regulation, and methionine synthesis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHematology Research:\u003c\/strong\u003e Employed in studies on megaloblastic anemia, pernicious anemia, and red blood cell development.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeurological Research:\u003c\/strong\u003e Studied for its role in myelin synthesis and neurological function, with deficiency linked to neurological impairment.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCobalamin Metabolism and Transport:\u003c\/strong\u003e Utilized as a tool to study cobalamin absorption (dependent on Castle's intrinsic factor and haptocorrin), transport via transcobalamins, and intracellular metabolism.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCell Culture and Microbiology:\u003c\/strong\u003e Used as a supplement in cell culture media and as a growth factor for certain bacteria (e.g., Lactobacillus lactis).\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"peptide-details\" open=\"\"\u003e\n\u003csummary\u003eProduct Specifications\u003c\/summary\u003e\n\u003cdiv class=\"peptide-content\"\u003e\n\u003cp\u003e\u003cstrong\u003eCAS Number:\u003c\/strong\u003e 68-19-9\u003cbr\u003e\u003cstrong\u003ePubChem CID:\u003c\/strong\u003e 16212801; also reported as 129893524\u003cbr\u003e\u003cstrong\u003eMolecular Formula:\u003c\/strong\u003e C₆₃H₈₈CoN₁₄O₁₄P; also reported as C₆₃H₈₉CoN₁₄O₁₄P\u003cbr\u003e\u003cstrong\u003eMolecular Weight:\u003c\/strong\u003e 1,355.37–1,355.39 g\/mol\u003cbr\u003e\u003cstrong\u003eAppearance:\u003c\/strong\u003e Red to dark red to dark purple powder or crystals\u003cbr\u003e\u003cstrong\u003ePurity:\u003c\/strong\u003e ≥ 99%\u003cbr\u003e\u003cstrong\u003eForm:\u003c\/strong\u003e Lyophilized powder or crystalline powder\u003cbr\u003e\u003cstrong\u003eStorage:\u003c\/strong\u003e Store at 2–8°C (refrigerated) for long-term storage, or at ≤ -20°C in a cool, dry place, protected from light\u003cbr\u003e\u003cstrong\u003eSolubility:\u003c\/strong\u003e Soluble in water (12,500 mg\/L); prepare working solutions per laboratory protocol\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e","brand":"yuansensetech","offers":[{"title":"B12  10mg","offer_id":52203316183330,"sku":"B12","price":55.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1008\/2805\/3794\/files\/10ml.jpg?v=1783741660","url":"https:\/\/yuansensepeptide.com\/products\/b12-peptide","provider":"Yuansensetech™","version":"1.0","type":"link"}
