Due to side reactions and inefficient synthesis of the radical species, chain initiation is not 100%.

Such reactions can be divided into three stages: chain initiation, propagation, and termination.

Translation starts with a chain initiation codon or start codon.

Cellulose synthesis requires chain initiation and elongation, and the two processes are separate.

The observed inverse pressure dependence of the induction periods was an indication that both chain initiation and termination were bimolecular.

Chain initiation:

The level of peptide chain initiation was high, as suggested by a significant inhibition of translation by edeine.

Like all chain-growth polymerizations, it takes place in three steps: chain initiation, chain propagation, and chain termination.

Chain Initiation: A free radical reaction mechanism step that has no radical reactant (s) and give radical product (s).

Taking the polymerization of ethylene as an example, the free radical mechanism can be divided into three stages: chain initiation, chain propagation, and chain termination.

This inhibition is probably at the level of chain initiation because it does not slow poly(U)-dependent elongation of poly(F).

The rate of chain initiation, R1, was controlled by using known amounts of the thermal initiator, di-tert-butylhyponitrite (DBHN).

Many radical reactions are chain reactions with a chain initiation step, a chain propagation step and a chain termination step.

Chain termination and chain transfer reactions are absent and the rate of chain initiation is also much larger than the rate of chain propagation.

Streptolydigin, an analogue of the tirandamycins, is known to function as an antibacterial agent through inhibiting the chain initiation and elongation steps RNA polymerase transcription.

Our structural data were consistent with the proposed function of lic2C, providing the first definitive evidence for its role as the glycosyltransferase required for chain initiation from HepII.

The rate of autoxidation of linoleic acid follows the classical rate law since it is proportional to the substrate concentration and to the square root of chain initiation.

Atom transfer radical polymerization or ATRP involves the chain initiation of free radical polymerization by a halogenated organic species in the presence of a metal halide.

Rates of oxygen absorption by styrene (RH) containing 2,2,3,3-tetraphenylbutane and zinc di-isopropyldithiophosphate at 30 °C obey the rate law where Ri is the rate of free-radical chain initiation.

The kinetic order in rate of chain initiation, Ri, was found to be one-half for both initiation by ADVN, photochemically decomposed, and by ABAP.

The initial rate of disappearance of the dithiocarbamate was equal to the rate of chain initiation (Ri) whereas the rate of disappearance of the dithiophosphate was twice as fast as Ri. In both cases the rate of complex disappearance slowed down as the complex was consumed.
