What did the scientist call the benzene ring that had iron atoms replacing the carbon ones?

A ferrous wheel!


What is Biochemistry?

In between the disciplines of Biology and Chemistry there is an area known as Biochemistry. This involves the study of what is going on in living cells on the molecular level. Let us know more...

We have diverse branches of chemistry. But there is one branch that is very important to study. Not only is it fascinating but it helps you get acquainted with your own body. Biochemistry is a broad but fascinating subject in which principles are developed and is used to study the important molecular processes in living things. DNA, enzymes, fats, carbohydrates and hormones are all part of the discipline of Biochemistry.

Molecules in Cells

In every living cell, there are a variety of different types of molecules. Many are very large, but are often made of repeating units, which in chemical terminology are called as polymers. Using the tools of the chemist, a biochemist studies the content of these bio-molecules and also the reactions in which they are involved.

Know the complexity

The study of biochemistry demonstrates the complexity of the contents and reaction pathways in even the tiniest, most simple cell. There are many reaction cycles and involves complicated enzymes and other compounds which depend on many various factors to function correctly. It is here that we begin to see the amazing complexity of life.

Proteins

It is said that "life" depends on chemicals called as proteins. These are polymers made up of repeating units which are called amino acids. Amino acids have a central carbon atom that is surrounded by four groups. One is a hydrogen atom. Two groups make the molecule an amino acid, first there is an amino group (-NH2) and second a carboxylic acid group (-COOH). The final group is unique to each different amino acid. There are twenty standard amino acids that are used in living systems. Amino acids join together when the amino group reacts with the carboxylic acid group to make a peptide bond (-NH-CO-).

Enzymes

Many proteins are used structurally in living things, but there are many others that are used as enzymes. Enzymes are long chains which fold up in specific ways because of the charges and other properties of the side groups. This macro-structure means that the enzymes act as very specific catalysts thereby creating specially shaped sites which take only the reagents needed and no others. In this way important reactions happen immediately when we need.

Nucleic Acids

Another important type of biochemical are the nucleic acids. There are two types of nucleic acid, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). These are complicated polymers that are made up of units called nucleotides. The main purpose of DNA is to store genetic information and to act as a pattern for the formation of important proteins.

Carbohydrates and Lipids

Carbohydrates and lipids are the other major types of biochemical. Carbohydrates serve two main purposes, to provide cell structure and energy to every cell. There are some very important reaction cycles through which carbohydrates provide energy to drive other important reactions. Very large polymer carbohydrates are used to provide cell structure in plants also known as cellulose. Lipids are the fatty chemicals which provide energy to the cell, but many are dangerous to human health. Cholesterol and trans-fatty acids are types of lipids.

This, biochemistry is an important study of the chemistry of living things and is sure to stay here as long as we have living things...
