Amino Acids In Cytoplasm: 7 Facts You Should Know

Amino acids in nature has its own amino and carboxylic acid functional groups as well as a unique side chain. Let us see some interesting facts about amino acids in cytoplasm.

Amino acids in cytoplasm are alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, histidine, isoleucine, leucine, lysine, methionine, phenylalanine, proline, serine, threonine, tryptophan, tyrosine, valine which are produced by the translation process.

The translation process takes place with the aid of an amino acid machinery called the ribosomes that are present in the cytoplasm. The end product of the translation process is the long amino acid chain.

Let us discuss if amino acids are found in cytoplasm, why they are found in cytoplasm, what kind of amino acids are found in cytoplasm and many other related questions in this article.

Are amino acids found in cytoplasm?

Almost every living system contains amino acids which are small peptide units. Let us see in detail if amino acids are found in cytoplasm or not.

Amino acids are found in cytoplasm. Cytoplasm consists of fluid or liquid-like substance in which all the contents of the cell freely floats. The fluid that is present inside the cytoplasm is rich in organic ions, sugars and amino acids.

Why are amino acids found in cytoplasm?

Cytoplasm, commonly known as cytosol has a lot of elements present inside it. Let us see why cytoplasm has amino acids in it.

Amino acids are found in cytoplasm because each and every cellular mechanism takes place only on the basis of the presence of amino acids. Transportation can be done easily only when amino acids are present in cytoplasm. The ribosomes, which synthesize the amino acid are also present in cytoplasm.

Where are amino acids found in the cytoplasm?

Amino acid has organic ions which are active agents for cellular mechanism. Let us see where precisely amino acids are located in the cytoplasm.

Amino acids are found in the fluid, that is present in the cytoplasm. The fluid contains active ingredients like amino acids, soluble salts, ions and sugars which are in the form of a gel like substance. The amino acid will then be transported to other organelles for other reactions.

What amino acids are found in cytoplasm?

Amino acids vary based on their morphology and functionality. To understand what all varieties of amino acids are present in the cytoplasm, please read below.

Glutamic acid and aspartic acid are found primarily in the cytoplasmic cell component. There are a number of other essential and non-essential amino acids present in the cytoplasm.

Functions of amino acids in cytoplasm

The role of amino acids varies based on the cell they are present in. Let us see their function in detail.

Some of the major functions of amino acids in cytoplasm is given below:

  • Memory is boosted by phenylalanine, which encourages a healthy nervous system.
  • Muscle growth is facilitated by valine.
  • Serotonin hormones and vitamin B3 are produced by tryptophan. Sleep and appetite are all managed by this serotonin hormone.
  • As a component of both red blood cells (erythrocytes) and white blood cells (leukocytes), histidine plays an important role in many enzymatic processes.
  • Protein synthesis and growth hormone production are promoted by leucine.
  • Our eyes, hair, skin, and hair contain natural pigments called melanin that are synthesized with tyrosine, such as thyroid hormones to produce T3 and T4 and synthesize a class of neurotransmitters.
  • The main function of proline is to repair tissues in the formation of collagen, prevent the thickening and hardening of arteries (arteriosclerosis), and regenerate skin.
  • We use asparagine in the transport of nitrogen into our cells, the synthesis of purines and pyrimidines, the development of our nervous system and enhancing our physical endurance.
  • Healing wounds is made possible by glycine, which maintains the proper growth and function of cells. In the brain, glycine has a role of neurotransmitter.
  • Protein synthesis and hormone production, kidney detoxification, wound healing, and immune function are all aided by arginine.

What is the source of free amino acids in cytoplasm?

We know that we need energy to survive, so how do we get amino acids for energy production. Let us know the solution.

The source of free amino acids in the cytoplasm is the food that a person consumes. Eg: The rice/ bread which is a carbohydrate when taken by a person, is converted to sugars. Likewise, the protein (lentils, chicken etc) is broken down to amino acids and is thus transported to each cell for cellular activity.

How are amino acids transported in the blood?

Blood has many components in it and one of them is amino acids. Let us see how amino acids are transported in the blood.

Amino acids are transported in the blood through systems called the L and Y+. Both of these systems are present in each and every cell of the living body and they aid in the transportation of the amino acids in the blood.


The article explains in detail regarding the amino acids in cytoplasm, their presence and their transportation, from where a person gets amino acids for cellular mechanism and also their role or functionality in each cell.
