Muriel Wheldale Onslow (1880–1932). British biochemist at Cambridge University, pioneer in biochemical genetics who worked on petal colour in flowers. Alexander Oparin, (1894–1980). Soviet biochemist at Moscow State University, known for his theory on the origin of life in coacervates.
Biochemistry is the study of the chemicals, chemical reactions and interactions that take place at a molecular level in living organisms. Biochemistry is highly interdisciplinary, covering medicinal chemistry, neurochemistry, molecular biology, forensics, plant science and genetics.
A protein is a polyamide. Secondary structure: regularly repeating local structures stabilized by hydrogen bonds. The most common examples are the α-helix, β-sheet and turns. Because secondary structures are local, many regions of different secondary structure can be present in the same protein molecule.
Clinical chemistry. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments.

At the bottom is the common phospholipid phosphatidylcholine. Lipids are a broad group of organic compounds which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K ), monoglycerides, diglycerides, phospholipids, and others.
Chirality is an important concept for stereochemistry and biochemistry. Most substances relevant to biology are chiral, such as carbohydrates (sugars, starch, and cellulose), all but one of the amino acids that are the building blocks of proteins, and the nucleic acids. Naturally occurring triglycerides are often chiral, but not always. In ...
Phosphorylation. Serine in an amino acid chain, before and after phosphorylation. In biochemistry, phosphorylation is the attachment of a phosphate group to a molecule or an ion. [1] This process and its inverse, dephosphorylation, are common in biology. [2] Protein phosphorylation often activates (or deactivates) many enzymes.
