How are fatty acids formed into lipids?
By: J. Gean
How Are Fatty Acids Formed Into Lipids? Lipids are formed in the body through a process known as esterification; a reaction where an acid and an alcohol combine to form an ester. In this reaction, the alcohol is always glycerol. Fatty acids combine with glycerol...
Proteins: The building blocks of life
By: Ussama Qadri
Proteins are the most important molecules in a cell. These are involved in almost all functions that go on in the cells. However, every function in the cell has a different set of protein molecules performing that function. Some protein molecules are involves in providing...
The diverse functions of RNA
By: Jeffrey Graf
Introduction In molecular biology, there has long been what has been referred to as the "central dogma", which holds that DNA stores genomic information, DNA is transcribed, or copied to messenger RNA which is in turn used by molecular machines composed of RNA called...
What is the alpha-complementation test?
By: Jeffrey Graf
The bacterium E. coli is the workhorse of the molecular biology lab. The biotechnology industry has grown up around using this common bacterium, an intestinal bacterium common to warm blooded animals, to multiply or expand a sequence or segment of DNA for future biotechnological use...
An overview of endocrinology
By: Tarek Musslimani
The systems of the body are in general under the control of the nervous system and the endocrine system. In this article I will discuss the endocrine system briefly. There are in the body many endocrine glands, the master of which is the pituitary gland...
How are amino acids built into proteins
By: Joshua Horn - 257112
Proteins are a critical part of the functioning of all life. They make up over 50% of the dry weight of any given living cell and are critical for many important biological processes and systems, including maintaining structure, catalyzing reactions and cell signaling. The basic...

Molecular dynamics is a tool for simulating the interactions between atoms or molecules. It utilizes basic Newtonian physics, by treating bonds and angles as springs, to approximate the motions of molecular structures. Because it is computational, it allows researchers to test hypotheses with unprecedented resolution...
The potential applications and benefits of the fullerene molecule: From electronics to medicine
By: Guy Takamatsu
The Nikkei Weekly (May 3, 2010. pg 16) had an article about the fullerene molecule and its wide range of possible applications. The fullerene is a hollow spherical shaped carbon molecule, whose existence was predicted by Japanese scientist Eiji Osawa. The actual molecule was discovered...

Amino acids are biologically significant compounds that are constituents of all proteins in the body. There are 20 amino acids that form the building blocks of all proteins. Each amino acid is composed of a CH group that to it attached an amino group and...

Metabolism or Replicators? There has been a debate over the origin of life that has been widely ignored in the mainstream of science. Today’s accepted theory is that of the ‘RNA world’ and it lacks the answers to many critical questions. The RNA...
