The first thing we are going to do in order to discover the meaning of the term albumin is to know what its etymological origin is. In this case, we can determine that it is a word that comes from Latin, more precisely "albumen, albuminis", which can be translated as "egg white".
It is called albumin to one protein : that is, at one molecule It is composed of amino acids that form different linear chains. Albumin refers to a class of protein found in the plasma of the blood , milk, egg white and the seeds of certain plants, among other sites.
The blood plasma, in the human being , is composed of albumin and globulins. Albumin is necessary to maintain the oncotic pressure , a particular form of osmotic pressure. Oncotic pressure allows body fluids to be distributed properly. Therefore, albumin is necessary for good organic functioning.
The distribution of certain hormones, fatty acids and drugs, the control of pH and the regulation of extracellular fluids are other functions that albumin develops in the organism . It should be noted that there are several disorders that can affect the presence of albumin in the blood plasma (in this case, we can specifically talk about serum albumin or serum albumin ): malnutrition, cirrhosis, nephrotic syndrome and others.
In the same way, we cannot forget the existence of what is known as low albumin, also called hypoalbuminemia. It is a deficit of this protein in the blood and usually occurs, especially in older people.
Kidney failures, anemia, liver diseases of different types, cancer or stomach problems are some of the situations that can lead to suffering from this situation that can be present through symptoms such as weakness and fatigue.
No less important is knowing that one can also talk about what is known as albumin in the urine. That protein can pass into the urine, yes, and when it does it is because the person in question is sick. Specifically, when that fact takes place it is because the kidneys do not work properly.
In order to detect if someone has albumin in their urine, they can choose to take the relevant sample of that waste substance. The results of the analysis done to this will dictate that the amount of albumin is normal if the concentration is less than 30 and that it is abnormal when it exceeds the figure of 30.
However, this data can also be known through the relevant blood test.
The albumin found in milk is called lactalbumin . It has a high level of sulfur amino acids and is in a colloidal state when it is in the dispersed phase.
The albumin that is in the egg white, finally, receives the first name from ovalbumin . This albumin represents between the 60% and the 65% of total egg proteins. It is estimated that albumin is used as a protein reservoir in the breeding of birds.
