Fats
Fats are the main energy storers of the body. On oxidation, fats give almost two and a half times the energy as that of glucose or glycogen. This makes it most suitable for energy storage. It, however, uses up more oxygen molecules during oxidation when compared to ..
Fats
Fats are also known as lipids. They are long molecules of fatty acids and an alcohol called glycerol. Fats contain the same elements as carbohydrates i.e., carbon, hydrogen and oxygen, but the oxygen content is lower. The main function of fats is t..
Carbohydrates - Introduction
Carbohydrates - Introduction - Carbohydrates are the organic molecules that are composed of elements carbon, hydrogen and oxygen. These carbohydrates are referred to as saccharides. Carbohydrates are defined as polyhydroxy-aldehydes or polyhydroxy k..

Proteins
Proteins are complex compounds made up of chains of nitrogen containing building blocks called amino acids. Besides nitrogen they also contain carbon, hydrogen and oxygen. The proteins present in living organisms contain more than 20 amino acids and each of them have a specific..

Hydrogen is the lightest substance known and the most abundant element in the universe. It has a mass of just 0.09 g per litre at normal temperature and pressure. Though it is present in abundance in celestial bodies, like the sun and stars, it is not present in a free state in our ..
Group 1 (IA) Element - Hydrogen Summary
Summary - Hydrogen is the most abundant element in the universe. Hydrogen is also the lightest element in the universe. It has a vapour density of 1, which is 14.4 times lighter than air. Hydrogen is absent in the free state in the earth's atmosphere. But in the combined state i..
