Organic chemistry: Amino acids made easy

Amino acids are the building blocks of proteins. There are 22 different amino acids and they can combine in a myriad ways to form a vast array of proteins. All amino acids except glycine are chiral molecules, meaning they ...

The 'natural' asymmetry of biological molecules may have come from space

Certain molecules do exist in two forms which are symmetrical mirror images of each other: they are known as chiral molecules. On Earth, the chiral molecules of life, especially amino acids and sugars, exist in only one form, ...

Mirror images united: Simultaneous binding of both enantiomers of a drug to an enzyme

(鶹ԺOrg.com) -- In the binding pockets of enzymes their natural binding partners fit exactly. The principle by which many pharmacological agents work also relies on the fact that these substances fit exactly into the pockets ...
