composition of lipid

Lipids are also organic compounds containing carbon, hydrogen and oxygen. However, hydrogen and oxygen occur in a ratio much higher than in water. Lipids form about 3.5% of the total chemical composition of a cell. Lipids are generally insoluble in wate..

These include the non-living, physico - chemical factors such as air, water, soil and the basic elements and compounds of the environment. Abiotic factors are broadly classified under three categories. Climatic factors which include the climatic regime and physical factors of the environment like ..

Summary - All living and non-living systems are composed of molecules which follow a specific set of physical laws. The molecules found in the living systems are called biomolecules. They are represented by the molecules of about 25 elements of the 109 elements known to exist. Carbon, Hydrogen, Oxy..

Introduction - The atmosphere resource of our world is unique and available to our planet only. No other planet is found to have similar atmosphere. Earth's atmosphere is a legacy from history of this planet. It was formed billions of years back. In the formative years, as the earth started cooling..

Biomolecules are complex organic molecules which built up living organism and form the basis of life. Biochemistry is the branch of chemistry which deals with the study of chemical composition and structure of living organism and chemical changes take place in them. Biochemical re..

fig. 14.4 - Levels of Structure in Proteins If the helical polypeptide molecule is folded on itself assuming a complex but specific structure such as spherical or rod like, then it is called tertiary structure. e.g., globulins of blood. Some proteins have two or more polypeptides, each with primary..
