The term "biguanidine" often refers specifically to a class of drugs that function as oral antihyperglycemic drugs used for diabetes mellitus or prediabetes treatment. [4] Examples include: Metformin - widely used in treatment of diabetes mellitus type 2; Phenformin - withdrawn from the market in most countries due to toxic effects
A detailed crystallographic analysis of guanidine was elucidated 148 years after its first synthesis, ... of biguanidine, ... 4) meaning that guanidine is a very ...
The rate of propagation is proportional to the concentration, [P•], of the active species P•, whereas the rate of the termination reaction, being second order, is proportional to the square [P•] 2. This means that during rate-retarded RAFT polymerizations, the rate of formation of termination products is suppressed to a greater extent ...
Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate.

In adults, daily synthesis of tissue constituents is nearly constant, and most constituents are removed with a first-order reaction rate. Applicability of the plateau principle was recognized during radioactive tracer studies of protein turnover in the 1940s by Rudolph Schoenheimer [ 2 ] and David Rittenberg . [ 3 ]

In molecular biology and biochemistry, processivity is an enzyme's ability to catalyze "consecutive reactions without releasing its substrate". [1]For example, processivity is the average number of nucleotides added by a polymerase enzyme, such as DNA polymerase, per association event with the template strand.
