Hormone, which comes from the Greek lexical vocabulary, meaning “setting exercises”, representing a crucial signaling role in the inverage of multicellular organisms.Hormones as signaling molecules were sent through complex biological processes to remote organs or tissues to regulate physiological and behavior.Hormones are inevitable in the animal, plant and even fungi.Since the hormones are quite wide and wide, many different types of molecules can be classified into hormones, including peanut acid, steroids, amino acid derivatives, proteins or polypeptides, and various substances such as gases.

In the presence of vertebrate, hormones in many aspects play important roles, surveillance from physiological processes to regulation of behavioral activity, such as awakening, excretion, breeding and emotional management.and in the plant, hormones affect almost every stage of development, from sprouts to aging.Through binding to specific receptor proteins, hormones affect remote cells, and the combination of combinations make cellular function changes.Once the hormone is bound to the receptor, it activates signal transduction pathways, and common matters promote gene transcription, thus increasing the expression of target proteins.Interesting, hormone action is not only limited to genomic pathways, but also can be performed through non-genome pathways.

Water-soluble-soluble hormone (such as polypeptides and amines) usually plays a role through the surface of the second messaging target cells, while lipid-soluble hormones (such as steroids) can act directly within the cell membrane, which acts directly within the cell nucleus.One-type in phytosteroids is dwarf steroidin, may show potential value in a certain endocrine-related tumor, which promotes cell apoptosis and restricts plant growth.The endocrine glands specialized in vertebrates specializes in the secretion of hormone secretion into the endocrine signaling system.Hormonal purses are often affected by specific biochemical signals and are commonly controlled by negative feedback.

For example, hyperglycemia promotes insulin synthesis, while insulin acts to lower blood sugar levels, which maintains stabilization in the vivo.

The endocrine system directly deep into the blood, usually through a windows of the capillaries, while the external secretion system indirectly secretes the hormone in the form of pipelines.In addition, there is a paracrine function Uyrolein, which spread through interstitial space to the nearby target organization through interstitial space.Plants are also stalled with specialized Ulidin-secret organs, and it still has hormone distribution of hormones.For example, growth is produced mainly in the top and apical division of young leaves.It means that the production site of litigins will change with the age and environment of the plant.

in the presence of hormones produces cells, usually located in the endocrine glands, such as thyroid, ovaries and testicles.The hormone signal transmission process includes several steps: specific tissues to synthesize specific Ued hormones, storage and secretion hormone, and then transports to target cells, and ultimately identifying hormone or intracellular receptor proteins.The process involves the signal magnification and transduction eventually leads to cell response, which in turn affects prototropic hormone production, forming a set of praise for negative feedback and hormone degradation is also important.

In the time of the time, I understand and constantly evolve.In 1849, German physiologist Arnold Adalf Bethold observed the same sexual act of Going Roosters as a complete testicle rooster, and a discovery of letting go began to study testosterone function research, and eventually revealed the secretion-secretary hormone secretion– testosterone.With the advancement of science, many other hormones discovery and naming are gradually clear, from the initial research of the Darwin father and son to the plant growth hormone to the present understanding of the complex role of a variety of hormones.

Projected to Future Ulidin Research, I think innocently: Is the God of God to the Chemical Signal that will change the way I live and health in the future?
