コレステロール

Cholesterol, also known as cholesterol, is a derivative of cyclopentane dihydrophenanthrene and an important component of various membrane structures and myelin sheaths in human cells.

A normal person weighing 70 kilograms contains approximately 140 grams of cholesterol in their body.

It is widely present in animal bodies, especially in the brain and nerve tissues, and its content is also high in the kidneys, spleen, skin, liver, and bile.

Its solubility is similar to fat, insoluble in water, and easily soluble in solvents such as ether and chloroform.

 Cholesterol is a naturally occurring sterol that serves as a fundamental structural component of cell membranes and a precursor for the biosynthesis of steroid hormones, bile acids, and vitamin D. This product is derived exclusively from plant sources (primarily lanolin or phytosterol conversion), making it suitable for applications requiring non-animal origin.

Plant-derived cholesterol is chemically identical to animal-derived cholesterol but offers advantages for vegan, vegetarian, and religious compliance (Halal/Kosher) applications. It is widely used in the pharmaceutical, cosmetic, and food industries as an emulsifier, stabilizer, and formulation aid.

Our cholesterol is available from three sources:

1. Animal-derived: economical, with a slight characteristic odor.
2. Fish oil-derived: suitable for dietary supplements and cosmetic applications, moderate cost, mild odor.
3. Plant-derived: recommended for cosmetic use, low odor, premium cost.

機能

• Membrane component: Structural building block of cell membranes, modulating membrane fluidity and permeability.

• Lipid delivery system: Used in liposome and nanoparticle formulations for drug delivery.

• Emulsifier: Stabilizes emulsions in cosmetic and pharmaceutical formulations.

• Hormone precursor: Starting material for semi-synthesis of steroid hormones (progesterone, testosterone, cortisol).

• Vitamin D precursor: Converted to 7-dehydrocholesterol and subsequently to vitamin D₃.
