Sialic acids are monobasic polyhydroxy amino acids that are derivatives of neuraminic acid. They are part of glycoproteins and glycolipoproteins, which play an important role in cellular metabolism and the functioning of the immune system.
Sialic acids are formed as a result of glycosylation of neuraminic acid, which is a component of cell membranes and is involved in various biological processes such as signal transduction, regulation of cell adhesion and immune response. In the human body, sialic acids can be found in various tissues, including the brain, liver, kidneys and other organs.
As part of glycoproteins, sialic acids perform the function of binding and protecting proteins from proteolytic enzymes. They are also involved in signaling between cells and regulate the activity of enzymes and receptors.
In addition, sialic acids play an important role in the functioning of the immune system, participating in the formation of antibodies and recognition of antigens.
Despite the fact that sialic acids are relatively small molecules, their role in the human body is very important. Their deficiency or dysfunction can lead to various diseases such as diabetes, Alzheimer's disease and some types of cancer.
Thus, sialic acids represent an important class of biologically active compounds that play a key role in cell metabolism and the functioning of the body as a whole. Studying their structure and functions is of great importance for understanding the mechanisms of development of various diseases and developing new treatment methods.
Sialic acids: What are they and how are they important for our body?
Sialic acids are monobasic acids that contain a derivative of neuraminic acid. They are often found in glycoprotein compounds, such as Brunmer's mucins, blood cells and some other biological structures. Sialic acid components are also found in some animal species, including pigs and cows, to help them fight off infections.
Functions of sialic acids:
* Protecting the body from infections - sialic acids help the body fight infectious agents due to their ability to bind viruses and bacteria. This can help prevent viruses from entering the body's cells. * Supports the immune system - sial clubroot play an important role in the functioning of the immune system: being components of leukocytes, leukotrophil cells, immunoglobulins and other immune components. * Strengthens the mucous membrane - acid sialoids can strengthen the mucous membrane of the nasal cavity, lungs, larynx and other organs. In addition, they can help protect tissue from damage during inflammation and other injuries.
In addition, sialic acids are involved in a number of biological processes, such as the renewal of old cells and restoration of damaged tissues, in the regulation of hormone levels, in the synthesis
