a desaturation at the sixth carbon of alpha-linolenic acid by a Δ6 desaturase to produce stearidonic acid (SDA, 18:4 ω-3), elongation of the stearidonic acid by a Δ6 elongase to produce eicosatetraenoic acid (ETA, 20:4 ω-3), desaturation at the fifth carbon of eicosatetraenoic acid by a Δ5 desaturase to produce eicosapentaenoic acid (EPA ...
This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
5 Benefits of DHEA Supplements for Men, From Depression Treatment to Increased Testosterone ... At age 70 to 80, DHEA levels may be down to 10 to 20 percent of those in a younger person. This drop ...
Triethylenetetramine (TETA and trien), also known as trientine when used medically, is an organic compound with the formula [CH 2 NHCH 2 CH 2 NH 2] 2.The pure free base is a colorless oily liquid, but, like many amines, older samples assume a yellowish color due to impurities resulting from air oxidation.
Hexylamine or n-hexylamine is a chemical compound with the formula CH 3 CH 2 CH 2 CH 2 CH 2 CH 2 NH 2. This colorless liquid is one of the isomeric amines of hexane. At standard temperature and pressure, it has the ammonia/bleach odor common to amines and is soluble in almost all organic solvents.
3-Pentanone (also known as diethyl ketone) is a simple, symmetrical dialkyl ketone. It is a colorless liquid ketone with an odor like that of acetone . It is soluble in about 25 parts water, but miscible with organic solvents.
N-Phenylacetyl-l-prolylglycine ethyl ester is promoted as a nootropic and is a prodrug of cyclic glycine-proline. [a] [2] Other names include the brand name Noopept (Russian: Ноопепт), developmental code GVS-111, and proposed INN omberacetam. [2] [3] [4] Its synthesis was first reported in 1996. [2] It is orally available.
3,4-Di methoxy phenethylamine (DMPEA) is a chemical compound of the phenethylamine class. It is an analogue of the major human neurotransmitter dopamine where the 3- and 4-position hydroxy groups have been replaced with methoxy groups. It is also closely related to mescaline which is 3,4,5-trimethoxyphenethylamine and to 3,4 ...
