chain

 [chān]
a collection of objects linked together in linear fashion, or end to end, as the assemblage of atoms or radicals in a chemical compound, or an assemblage of individual bacterial cells.
branched chain an open chain of atoms, usually carbon, with one or more side chains attached to it.
closed chain several atoms linked together so as to form a ring, which may be saturated, as in cyclopentane, or aromatic, as in benzene.
H chain (heavy chain) any of the large polypeptide chains of five classes that, paired with the L or light chains, make up the antibody molecule of an immunoglobulin; heavy chains bear the antigenic determinants that differentiate the classes of immunoglobulins. See also heavy chain disease.
J chain a polypeptide occurring in polymeric IgM and IgA molecules.
L chain (light chain) either of the two small polypeptide chains (molecular weight 22,000) that, when linked to H or heavy chains by disulfide bonds, make up the antibody molecule of an immunoglobulin monomer; they are of two types, kappa and lambda, which are unrelated to immunoglobulin class differences.
open chain a series of atoms united in a straight line; components of this series are related to methane.
chain reaction a chemical reaction that is self-propagating; each time a free radical is destroyed a new one is formed.
side chain a group of atoms attached to a larger chain or to a ring.

side chain

1. a chain of noncyclic atoms linked to a benzene ring, or to any cyclic chain compound;
2. the atoms of an α-amino acid other than the α-carboxyl group, the α-amino group, the α-carbon, and the hydrogen attached to the α-carbon.

side chain

1. A chain of noncyclic atoms linked to a benzene ring, or to any cyclic chain compound.
2. The atoms of an α-amino acid other than the α-carboxyl group, the α-amino group, the α-carbon, and the hydrogen attached to the α-carbon.

side chain

commonly referred to as −R; group that confers specific identity to compounds, particularly amino acids.

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.
These results obtained on thermochromic polythiophenes support the assumption that side-chain disordering can be the driving force for the twisting of the conjugated backbone and, therefore, using appropriately functionalized conjugated polymers, it can be expected that a large number of external stimuli can also lead to chromic effects.
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.

According to the company, DALVANCE for injection is a second generation, semi-synthetic lipoglycopeptide, which consists of a lipophilic side-chain added to an enhanced glycopeptide backbone.
The topics include macromolecules and Chimera, algorithms dealing with distance, structure overlap and alignment, and rotamers and side-chain conformation.
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.
