What is the key difference among the 20 amino acids that are used to make proteins?

Ray Of Light [21]

Answer:

Attached R side groups

Explanation:

The proteins are one of the important biomolecules which are directly coded by the genetic material of an organism.

The proteins are composed of the amino acids which possess, an amine group, a carboxylic group and an attached side group called the R group.

It is the R group of an amino acid which determines whether the amino acid will a polar or a non-polar amino acid molecule thus it determines the properties of the amino acid in terms of chemical properties. The R side group are involved in the formation of bonds with the substrate of the environment and the tertiary structure of the proteins.

Thus, the presence of different R group is the key difference in 20 amino acids.

A 30-year-ol of HIV with a CD4 cell count of 120 cells (normal, 1000–1500). He had an ulcerating lesion on the side of his tongu

Lady_Fox [76]

HIV is the human immunodeficiency virus. Causer of AIDS, it attacks the immune system, responsible for defending the body from diseases. The most affected cells are CD4+ T lymphocytes. And it is by altering the DNA of that cell that HIV makes copies of itself.

<h3>1. Discuss the pathophysiology of HIV in relation to the reduction of CD4 cells</h3>

HIV binds to a component of that cell's membrane, CD4, penetrating its interior to multiply. As a result, the defense system gradually loses the ability to respond properly, making the body more vulnerable to disease.

<h3>2. Discuss the body's immune response to the virus (HIV)</h3>

The innate immune responses to HIV infection are mainly the intense production of cytokines, such as interleukin (IL)-1 and interferon (IFN)-1, and the activation of natural killer (NK) cells, which can temporarily control HIV replication. through apoptosis of infected cells

<h3>3. Explain the molecular and cellular immune response that leads to the swollen lesion.</h3>

due to the accumulation of primary immune cells and the body's long attempt to fight the infection

<h3>4. Discuss the cellular and molecular immune response that results in enlargement of the spleen and cervical lymph nodes</h3>

An infection from bacteria and viruses, including HIV, can cause swelling of the lymph nodes. The swelling occurs because the infection reaches the nodes through lymph fluid. HIV most often affects lymph nodes around the neck as well as in the armpits and groin.
