Testing Ames test – salmonella bacteria is exposed to a chemical under question (a food additive, for example), and changes in the way the bacteria grows are measured.. This test is useful for screening chemicals to see if they mutate the structure of DNA and by extension identifying their potential to cause cancer in hu
Biochemistry, or biological chemistry, is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...
A large fraction of the chemical elements that occur naturally on the Earth's surface are essential to the structure and metabolism of living things. Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm. [1]
Modern biochemistry is considered a sub-discipline of the biological sciences, due to its increased reliance on, and training, in accord with modern molecular biology. Historically, even before the term biochemist was formally recognized, initial studies were performed by those trained in basic chemistry , but also by those trained as physicians .
3′-Phosphoadenosine-5′-phosphosulfate (PAPS) is a derivative of adenosine monophosphate (AMP) that is phosphorylated at the 3′ position and has a sulfate group attached to the 5′ phosphate.
Biochemistry is the chemistry of life. Biochemists study the elements , compounds and chemical reactions that are controlled by biomolecules (such as polypeptides , polynucleotides , polysaccharides , lipids and chemical messenger [ disambiguation needed ] s) and take place in all living organisms .

Due to these factors, the journal's practice of publishing a broad cross-section of biochemistry articles has led it to suffer in impact factor, in 2006 ranking 260 of 6,164, while remaining a highly cited journal. [6] When science journals were evaluated with a PageRank-based algorithm, however, the Journal of Biological Chemistry ranked first ...
