Collection: Vitamins [Nutrition Research]

Vitamins [Nutrition Research] — a collection of water-soluble and fat-soluble vitamins and their derivatives, such as phosphorylated, esterified, or sulfonated forms, plus other terpenoid groups that are biosynthetically related, studied as reference compounds in metabolism and nutrition research.

Compounds in this category are used as in vitro test materials and reference compounds in nutrition research to study vitamin metabolic pathways, enzymatic cofactors such as pyridoxal 5-phosphate, and structure-function relationships between vitamins and related terpenoids. Biochemistry and nutrition researchers use them for calibrating analytical methods, cell culture models, and biosynthesis pathway studies involving B-complex vitamin derivatives as well as secosteroid groups such as cholecalciferol.

Example products in this collection: TCI C0314 67-97-0 Cholecalciferol, TCI B6302 22150-76-1 6-Biopterin, TCI A0520 89-65-6 D-Araboascorbic Acid, TCI C0005 50-14-6 Calciferol, TCI A0537 50-81-7 L-Ascorbic Acid, TCI C0377 41468-25-1 Pyridoxal 5-Phosphate Monohydrate, TCI A0539 134-03-2 Sodium L-Ascorbate, TCI C0449 68-19-9 Vitamin B12.

Pay attention to specific chemical forms (sodium salt, hydrate, or phosphorylated forms), purity, and stability toward light and temperature, because many vitamins and related terpenoids degrade easily. All products are genuine products of Tokyo Chemical Industry (TCI) Japan, with purity, packaging, and storage conditions listed on each item's page.

Other parallel categories under Nutrition Research, often used together in one laboratory workflow:

• Phytochemicals
• Functional Food Research

This collection is further divided into 2 more specific groups:

• Vitamin Derivatives
• Terpenes (Others)
