side chain

[′sīd ‚chān]
(organic chemistry)
A grouping of similar atoms (two or more, generally carbons, as in the ethyl radical, C2H5‒) that branches off from a straight-chain or cyclic (for example, benzene) molecule. Also known as branch; branched chain.

Furthermore, MEHP was specific for aromatase and did not decrease transcript levels of the cholesterol side-chain cleavage enzyme (P450scc) in the granulosa cell.
The structure was similar to the earlier reported R-state structures, but there were differences in many side-chain conformations, the presence of a phosphate ion, and the position of the associated water structure.
4] On the basis of this model, this cooperative conformational transition could be explained by the formation of assemblies of well-defined conjugated macromolecules that are disrupted upon side-chain disordering.

DALVANCE is a second generation, semi-synthetic lipoglycopeptide, which includes a lipophilic side-chain added to an enhanced glycopeptide backbone.
Both main-chain siloxanes with two average molecular weights of 3200 and 5600 (g/mol) and side-chain siloxanes with average molecular weights of 2500, 4900, and 16,000 (g/mol) were purchased from Shin-Etsu.
Same-spec" resin from different plants, even different reactors, of the same supplier can differ in crosslinking, molecular-weight distribution, side-chain branching, or pellet size.
For the case of alpha-lactalbumin, the neutron results show that the side-chain protons in the molten globules are significantly more mobile than those in the native protein.
The chemistry proposed will lead to the preparation of new side-chain polymers bearing ligands with an N3 donor set, which can be used to complex a range of metal ions.
Generally, since polymethacrylic acids exhibit higher glass transition temperature than polyacrylic acids, the reason for those differences of surface morphology is suggested by the influence of packing hindrance for fluorinated side-chain by arrangement of low mobility methacrylate main-chain.
The results, show that the side-chain protons in the molten globules are significantly more mobile than those in the native protein.
The company's side-chain crystalline (SCC) polymers are finely powdered acrylic copolymers with sharp melting points that can be tailored to within 1 [degree] C in a range of 0 to 100 C.
