Egg contain 67 per cent proteins (in egg white) and 33 per cent fats and proteins (in egg yolk). Egg white protein is mostly albumin (ovalbumin and Conalbumin) All proteins have primary,secondary and tertiary structures. Tertiary structure of egg white protein is due to hydrophobic interactions and hydrogen bonding. They also contain Cysteine amino acid, which has sulfhydryl group (SH). These sulfhydryl groups form covalent disulfide bonds and hold 2 distant sections of proteins in close proximity. Disruption of the tertiary structure (or 3 dimensional structure) due to heat, chemicals or acidity is called "denaturation". When we heat an egg, the, heat breaks the intermolecular forces and the tertiary structure gets broken. The proteins unfold from their nature folded structure and precipitate forming a white solid mass. |

Why to Shout in Anger
A Hindu saint who was visiting river Ganges to
take bath found a group of family members on the banks, shouting in anger at
each other. He turned to his disciples smiled 'n asked.
'Why do people shout in anger shout at each
other?'
Disciples thought for a while, one of them
said, 'Because we lose our calm, we shout.'
'But, why should you shout when the other
person is just next to you? You can as well tell him what you have to say in a
soft manner.' asked the saint
Disciples gave some other answers but none
satisfied the other disciples.
Finally the saint explained,
.
'When two people are angry at each other, their
hearts distance a lot. To cover that distance they must shout to be able to hear
each other. The angrier they are, the stronger they will have to shout to hear
each other to cover that great distance.
What happens when two people fall in love? They
don't shout at each other but talk softly, Because their hearts are very close.
The distance between them is either non-existent or very
small...'
The saint continued, 'When they love each other
even more, what happens? They do not speak, only whisper 'n they get even closer
to each other in their love. Finally they even need not whisper, they only look
at each other 'n that's all. That is how close two people are when they love
each other.'
He looked at his disciples and said:
'So when you argue do not let your hearts get distant, Do not say
words that distance each other more, Or else there will come a day when the
distance is so great that you will not find the path to return.' !!!

Bend but Don't Break (Story)
One of my fondest memories as a child is going by the river and sitting idly on the bank. There I would enjoy the peace and quiet, watch the water rush downstream, and listen to the chirps of birds and the rustling of leaves in the trees. I would also watch the bamboo trees bend under pressure from the wind and watch them return gracefully to their upright or original position after the wind had died down.
When I think about the bamboo tree's ability to bounce back or return to it's original position, the word resilience comes to mind. When used in reference to a person this word means the ability to readily recover from shock, depression or any other situation that stretches the limits of a person's emotions.
Have you ever felt like you are about to snap? Have you ever felt like you are at your breaking point? Thankfully, you have survived the experience to live to talk about it.During the experience you probably felt a mix of emotions that threatened your health. You felt emotionally drained, mentally exhausted and you most likely endured unpleasant physical symptoms.Life is a mixture of good times and bad times, happy moments and unhappy moments. The next time you are experiencing one of those bad times or unhappy moments that take you close to your breaking point, bend but don't break. Try your best not to let the situation get the best of you.A measure of hope will take you through the unpleasant ordeal. With hope for a better tomorrow or a better situation, things may not be as bad as they seem to be. The unpleasant ordeal may be easier to deal with if the end result is worth having.If the going gets tough and you are at your breaking point, show resilience. Like the bamboo tree, bend, but don't break!--SenthilNever cry for any relationship in life, for the one whom you cry does not deserve your tears/love and the one who deserves your tears/love will never let you cry.
