Amino Acid: Structures, Types, Function

Amino Acid a Group of organic molecules made up of amino acid. Each amino acid has its own basic amino acid (-NH2), acidic group of carbohydrates (-COOH), and organic group R (or side chain). Carboxylic acid is what is meant by the term -amino for an amino acid. Each protein has a carbon (C) atom in the middle, which is called carbon. The amino and carboxyl groups are related to carbon. Most of the time, the hydrogen (H) atom and the R group fill the last two bonds of the -carbon atom.

What are amino acids?

Amino acids are carboxylic acids that contain amino groups. The -amino acid is the most important type of amino acid. Amino acids consist mainly of carbon, nitrogen, oxygen, hydrogen, and other natural elements. There are approximately 500 amino acids known to science, but only 20 are considered to be of significant importance and use.

The most common amino acids have a carboxy group, an amino group, and a side chain that is referred to as the R group. All of these groups are connected to the -carbon.

Types of Amino Acids List

Here is a list of the most common amino acids, along with the three-letter and one-letter codes (uppercase) of the amino acid symbols that most people are familiar with. This paper used for quick marking of amino acids and is easy to learn.

  • alanine – ala – A
  • arginine – arg – R
  • asparagine – asn – N
  • aspartic acid – asp – D
  • cysteine – cys – C
  • glutamine – gln
  • glutamine – gln – Q
  • glutamic acid – glu – E
  • glycine – gly – G
  • histidine – his – H
  • isoleucine – ile – I
  • leucine – leu – L
  • lysine – lys – K
  • methionine – met – M
  • phenylalanine – phe – F
  • proline – pro – P
  • serine – ser – S
  • threonine – thr – T
  • tryptophan – trp – W
  • tyrosine – tyr – Y
  • valine – val – V

Classification of amino acids on the basis of R-group

  1. Non-polar, aliphatic amino acids: These amino acids include R groups that are both non-polar and hydrophobic in nature. Glycine, Elenin, Valine, Leucine, Isoleucine, Methionine, Proline.
  2. Aromatic amino acids: The amino acids phenylalanine, tyrosine, and tryptophan, as well as the aromatic side chains of these amino acids, are highly hydrophobic. Hydrophobic interactions are open to anybody who wants to take part in them.
  3. Polar, polar amino acids: When compared to non-polar amino acids, the R groups of these amino acids are more hydrophilic, which means that they are more soluble in water. This is because they include functional groups that create hydrogen bonds with water. Serine, threonine, cysteine, asparagus, and glutamine are all examples of these types of amino acids.
  4. Acidic amino acids: R-groups are amino acids that are either acidic or have a negative charge. Glutamic acid with aspartic acid
  5. Basic amino acids: R-groups are basic or positively charged amino acids. Lysine, arginine, Histidine.

Classification of amino acids on the basis of nutrition

Amino Acids Essential types

Because the body is unable to produce nine different kinds of amino acids, protein synthesis requires that these amino acids be obtained from the food.

Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the necessary amino acids. Valine is also an essential amino acid.

Amino Acids Non-essential

Because the body is capable of naturally producing certain amino acids, there is no need that they come from the food.

Arginine, glutamine, tyrosine, cysteine, glycine, proline, serine, ornithine, elenin, asparagus, and aspartic acid are some of the amino acids that are essential to human health.
