Amines are organic compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are derivatives of ammonia, wherein one or more hydrogen atoms are replaced by organic substituents such as alkyl and aryl groups. Compounds with the nitrogen atom next to a carbonyl of the structure R-C(=O)NR 2 are called the amides and have different chemical properties. Important amines include amino acids, biogenic amines, trimethylamine and aniline; see CategoryAmines for a list of amines. As displayed in the images below, primary amines arise when one of three hydrogen atoms in ammonia is replaced by an organic substituent. Secondary amines have two organic substituents bound to N together with one H. In tertiary amines all three hydrogen atoms are replaced by organic substituents. It is also possible to have four alkyl substituents on the nitrogen. These compounds have a charged nitrogen center, and necessarily come with a negative counterion, so they are called quaternary ammonium salts. Similarly, an organic compound with multiple amino groups is called a diamine, triamine, tetraamine and so forth. Aromatic amines have the nitrogen atom connected to an aromatic ring as in anilines. The aromatic ring strongly decreases the alkalinity of the amine, depending on its substituents. Interestingly, the presence of an amine group strongly increases the reactivity of the aromatic ring, due to an electron-donating effect. One organic reaction involving aromatic amines is the Goldberg reaction.

1. Anti Aging Amino Acids can reverse Aging
September 22, 2008
Anti aging amino acids are the building blocks of proteins in the human body. Amino acids are crucial for the growth and maintenance of the body. They build cells, repair tissues, form antibodies and take part in the formation of nucleoproteins. Indirectly, a proper balance of amino acids in the human body can retard the aging process. Amino acids have been converted into anti aging nutritional supplements with great success. Anti Aging Amino Acids With the power of anti aging, amino acids are chemical compounds of the amine and carboxyl functional groups. Amino acids play a key role in the... (read more)

4. Vitamins - Do They Really Help?
April 30, 2008
The word “vitamin” is derived from two words, “vital” and “amine”. Vitamins are known to be really powerful organic compounds available in little concentrations in different food sources. Vitamins are supported to function in certain specific ways and their role is vital for the body chemistry. These can be compared to electric sparks that help in ‘running’ human motors.
Vitamins cannot be produced or even synthesized by the organism. Of Course, there are certain exceptions. The absence of vitamins or absorption in lesser amounts than required can result in certain deficiencies and also d... (read more)

5. 20 Common Amino Acids That Keep You Alive
October 26, 2007
Amino acids refer to the molecular structure consisting of both amine and carboxyl functional groups. Referred to as alpha-amino acids in Biochemistry, typically it is defined with the formula H2NCHRCOOH where R stands for organic substitute. Amino acids can be called as the building blocks of our life. They get combined in an unlimited number of configurations to construct all the required proteins with which our body is built. There are essentially 20 common amino acids that keep us alive, healthy and energetic. If deficiency occurs in an individual amino acid, it may create serious problem... (read more)

8. Glucosamine
April 20, 2006
GlucosamineHelps to reduce pain and inflammation What is Glucosamine?Glucosamine is made from the sugar combination. The first part of the name glucos is derived from the word glucose and the second one is amine, which is a derivative of ammonia containing nitrogen and hydrogen atoms. Glucosamine is found largely in cartilage and plays a key role in its health and resiliency. As we get older, we lose some of the glucosamine and other substances in cartilage. This can lead to thinning of cartilage and the onset and progression of osteoarthritis. It is very important to note that there are lots ... (read more)

9. Give Your Body Its Vitamin Supplements!
October 14, 2005
What are vitamins? The term 'vitamin' was first given to a group of substances that were thought to be vital for life, each containing a nitrogen-containing component known as an amine. Vitamins are essential for the proper functioning of our body. They help to strengthen the immune system, to ward off disease, and even to improve the overall mood of a person. If a particular vitamin is missing from your diet, it may lead to a deficiency disease.
Vitamins can help prevent diseases mainly in two ways. First, they prevent the deficiency syndromes characteristic of the respective vitamin. Seco... (read more)
