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.

Nursery and Kindergarten Admissions in Delhi/NCR Schools: What’s the age?

It is the most intricate issue of the current time in India. What should be the exact age of kids at the time of nursery admissions ? Lot of different perspectives and ideas are there, but in my opinion, the ideal age for kindergarten should be 5-6 years. I think we first let them enjoy their childhood, let them develop in all directions. Give them some more years or going play group is sufficient. But the opinions vary here, and everyone has her view on this matter. Some parents don’t want to send them at an early age, but they have no choice. These days mostly schools are taking 3+ kids for nursery and 4+ kids for KG . There are also some schools that prefer to take 4+ kids for nursery or they start from KG classes. The education system is growing more complicated as they don’t focus on the abilities of child and parents. Strict criteria and some guidelines are put, and that’s all. The most painful thing is the distances between schools and homes, how our little buds ca

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.
