Oxygen-17&18 (17O & 18O)

Oxygen-17 (17O) and Oxygen-18 (18O) are both stable isotope atoms of Oxygen-16 (16O). With the increasing number of organic compounds containing atoms of oxygen isotopes, they are used in different areas of research.

Oxygen-17&18 (17O & 18O) (4):

Cat. No. Product Name CAS No. Purity Chemical Structure
  • HY-N0322S8
    Cholesterol-18O 59613-51-3
    Cholesterol-18O is the deuterium labeled Cholesterol. Cholesterol is the major sterol in mammals and is makes up 20-25% of structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively impermeable to ions and protons. Cholesterol plays an important role in determining the fluidity and permeability characteristics of the membrane as well as the function of both the transporters and signaling proteins. Cholesterol is also an endogenous estrogen-related receptor α (ERRα) agonist.
  • HY-N0473S12
    L-Tyrosine-17O 104931-15-9
    L-Tyrosine-17O is the 17O-labeled L-Tyrosine. L-Tyrosine is a non-essential amino acid which can inhibit citrate synthase activity in the posterior cortex.
  • HY-N0384S3
    Homovanillic acid-13C6,18O 202468-52-8
    Homovanillic acid-13C6,18O is the 13C-labeled Homovanillic acid. Homovanillic acid is a dopamine metabolite found to be associated with aromatic L-amino acid decarboxylase deficiency, celiac disease, growth hormone deficiency, and sepiapterin reductase deficiency.
    Homovanillic acid-13C6,18O
  • HY-N0486S10
    L-Leucine-18O2 73579-45-0
    L-Leucine-18O2 is the 18O-labeled L-Leucine. L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway.
