High-performance liquid chromatography (HPLC) is now firmly established
as the premier technique for the analysis and purification of a wide range of
molecules. In particular, HPLC in its various modes has become the central technique in the characterization of peptides and proteins and has, therefore, played
a critical role in the rapid advances in the biological and biomedical sciences
over the last 10 years.
The enormous success of HPLC can be attributed to a number of inherent
features associated with reproducibility, ease of selectivity manipulation, and
generally high recoveries. The most significant feature is the excellent resolution that can be achieved under a wide range of conditions for very closely
related molecules, as well as structurally quite distinct molecules. This arises
from the fact that all interactive modes of chromatography are based on recognition forces that can be subtly manipulated through changes in the elution conditions that are specific for the particular mode of chromatography. Peptides
and proteins interact with the chromatographic surface in an orientationspecific manner, in which their retention time is determined by the molecular
composition of specific contact regions. For larger polypeptides and proteins
that adopt a significant degree of secondary and tertiary structure, the chromatographic contact region comprises a small proportion of the total molecular surface. Hence, the unique orientation of a peptide or protein at a particular
stationary phase surface forms the basis of the exquisite selectivity that can be
achieved with HPLC techniques. All biological processes depend on specific

Biologically

Biology is a natural science that is concerned with the study of life, its various forms and its function, how these organisms interact with each other and with the surrounding environment. The word biology in Greek is made up of two words: bio (βίος) meaning life. And loggia (-λογία) means science or study. Biology: the similarity of vegetation and animal cover on the edges of the African and American states, and the existence of the same fossil.


Branches of biology
Biology is an ancient science thousands of years old and modern biology began in the nineteenth century. This science has multiple branches. Among them are:

Anatomy
Botany
Biochemia
Biogeography
Biofisia
Cytology or cell science
Ecology or environmental science
