e-Content

I am at present at a workshop related to e-content. What is e-content? It is a big question. Educationists, authors, teachers, students, I mean everyone associated with educational arena may certainly have a different view because there are individual differences.
I have been told that we have do away with the traditional way of preparing the audio-visual teaching aids. I wonder if there is any way to prepare an e-content which should not follow the principle, " one principle fits all".
इ - कंटेंट का मतलब शायद है कोई भी ऐसा इलेक्ट्रौनिक माध्यम जो शैक्षणिक महत्तव का हो क्या इ - कंटेंट ऐसे लोग बना सकते हैं जो अध्ययन और अध्यापन से जुड़े नहीं हों

Proteins
The name protein is derived from the Greek word proteios, which means first important. G. V. Mulder coined this term in 1835 when he identified that these nitrogen containing organic compounds were essential for all life processes.
Proteins are copolymers made of 20 different amino acids. Many lower animals can synthesize all of these amino acids, but humans can not. Hence humans must obtain 8 of these from their diet. Fortunately, soyabeans, which have served as staple food for centuries, contain all the essential amino acids.
