Amino Acids: importance in life


Amino acids are quintessential molecules of life; these are the building blocks of Proteins. And we know that protein is the basis of life, which acts in each step of our life-cycle, helps in making each piece of the body, and fulfills the need of our supplements. Its’ unit “Amino Acids” serve as substrate for many live mechanisms.

Actually Amino Acids are Carboxylic Acid, which contains at least one amino acid. A general formula of amino acids is:

                                                       R-CH-(NH2)-COOH


On the base of chemical composition, they are found in various characteristics.


  • Some of them contain aliphatic hydrocarbon chains, (Glycine, Alanine, Valine, Leucine, Isoleucine),
  • Some of them are completed with aromatic side chains (Phenylalanine, Tyrosine, Tryptophan),
  • Amino Acids with acidic side chains (Aspartic Acid, Glutamic Acid),
  • Amino Acid with Hydroxyl Groups (Serine, Threonine),
  • Amino Acid with Basic side chain (Lysine, Arginine),
  • Amino Acid with Imidazoles(Histidine),
  • Amino acids with Sulphur (Cysteine, Cystine, Methionine), &
  • Amino Acid with Pyrollidine ring (Proline, Hydroxyproline).

Amino acids are crystalline and colorless molecules with an average weight of 120 D. Some of them are synthesized inside the body while others are required to take through dietary supplements.

Every Amino Acid has some unique triplet base codes, and this may vary up to 4 but each code denotes only a distinct Amino Acid. A slight change in this code can alter the protein functioning and produce abnormalities.

Generation of Random amino acid protein sequences using Python/Bio-python

This program is about how to generate protein sequences (random sequences of 100amino acid) and these sequences should be stored in a database type file. The sequence analysis gave the bioscience researches a new direction. This project works for generating new sequences of proteins. These sequences might already exist in nature and having similarity with any organism. Through this software new random sequences may be generated and saved to a file on user’s machine. Saving to file helps to compare different sequences as well as the complete information may be placed at the same place. The Protein generation part is a simple program which takes in user input for number of random Protein Sequences to generate and filename/file-path. Based on these user inputs random Protein sequences are generate of 100 amino acid residues of type IUPACProtein. The sequences thus generated are saved to a file in the current directory by the name username.fasta in Fasta format. This program is in Python L

Green tea benefits

Green tea is a form of the leaves from the same tea plant, Camellia sinensis . It is less oxidised than black tea, but more than  white . The Green tea benefits have been proved remarkably promising in cancer and heart diseases. Presence of strong antioxidants makes it unique, theses anti-oxidants forage free radicals of our cells to wipe them out. Green tea benefits include the presence of  healthy  polyphenols and the most prominent poly-phenol is epigallocatechin gallate. Some main benefits of green tea are noticed in the case of Rheumatoid arthritis, High cholesterol levels, cardiovascular disease and in the improvement of the immune system. For weight loss and fat  burn  green tea is the best source of fitness.  Must add this nature's gift to your routine. Other varieties of Chinese teas are Bancha, Kabusecha, Gyokuro, Matcha and Tencha etc.

Eczema flare-ups-- Still a big question

What Causes Eczema? Generally eczema develops after frequent exposure to a mild irritant like a detergent or a concise exposure to a burly irritant such as acid etc. On the other side, allergic contact eczema builds up when an allergen comes in the contact with skin, like poison ivy and nickel. The exact reason behind its growth is still standing like a big question. Researchers believe that atopic eczema might be a result of blending various factors; these factors include heredity of certain genes, an overactive immune system, or "gaps in the skin". These gaps let the skin lose water too fast and also allow germs to enter the body. Generally Eczema bursts in cold and dry weather. Seborrheic is the other form of eczema that seems to develop when a number of factors interact which may include the person's genes; climate,fungus that live on human skin, stress, and general health. Present forms of Eczema: Atopic Eczema is a chronic skin condition that causes itchy, d
