Dopamine, Norepinephrine and Ephinephrine Synthesis

Dopamine-β-hydroxylase is located inside amine storage vesicles of norepinephrine neurons. Dopamine is actively transported from the cytoplasm into the vesicles. As the enzyme is a copper containing protein, its activity can be inhibited by copper chelating agents, such as diethyldithiocarbamate

Chemokine Receptors

Papain, Cysteine Protease, Properties & Products

Uncover properties and applications of the cysteine protease papain and find inhibitors, substrates, and other papain products.

Cholesterol Biosynthesis Regulation

Cholesterol synthesis regulation by dietary levels, LDL receptors control lipid-rich LDL particle transport in cells.

Serotonin Synthesis & Metabolism

Serotonin is stored in cells and metabolized by MAO, influencing CNS, GI, and platelet functions.

Dopamine Synthesis

Dopamine-β-hydroxylase inhibition reduces tissue norepinephrine levels, offering potential therapeutic benefits.

Cholesterol Biosynthesis

Cholesterol biosynthesis starts in the hepatic endoplasmic reticulum with acetyl-CoA, yielding 3-hydroxy-3-methylglutaryl-CoA via HMG-CoA synthase.
