glucose, C6H12O6,is a simple monosaccharide carbohydrate; it is a product of photosynthesis and the starting material in cellular respiration

this is real science.

diborane, B2H6, is a dimer of the molecule borane (BH3); it is a potent reducing agent (electron donor) in synthetic organic chemistry

the Kaminsky catalyst is a catalytic system developed in 1980 for the polymerization of alkenes, C=C double bonds

dimerization

diisobutylaluminum hydride, DIBALH, is common electrophilic reducing agent in the field of organic synthesis; a common reaction (see example below) is the conversion of  an ester, -CO2R, to an aldehyde, -CHO

capsaicin, C18H27NO3, is the active component of ‘hot’ peppers; it binds to receptors on the tongue, causing the characteristic ‘spicy’ taste of chili peppers

cyclophosphamide, C7H15Cl2N2O2P, is sold under trade names such as ENDOXAN and CYTOXAN; it is an organophosphorus (C-P) DNA alkylating agent which binds to the nitrogenous base guanine
