Glycine crystals, light micrograph
Glycine crystals. Polarised light micrograph of crystals of glycine, the simplest of the amino acids. Glycine consists of a central carbon atom, to which are attached two hydrogen atoms, one amino group and one carboxyl group. It is a neurotransmitter and important in metabolism because it contributes carbon atoms in the formation of the blood pigments. Glycine is also used in the synthesis of adenine and guanine, two of the nucleic acids, and is incorporated into protein directly. It is likely to have been the first amino acid formed on Earth at the time of the primeval soup. Magnification: x120 when printed at 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of glycine crystals, captured under polarised light. Glycine, the simplest amino acid, is depicted here in all its crystalline glory. At the core of each crystal lies a central carbon atom surrounded by two hydrogen atoms, an amino group, and a carboxyl group. Beyond its aesthetic appeal, glycine plays crucial roles in various biological processes. As a neurotransmitter, it facilitates communication between nerve cells. Additionally, it contributes carbon atoms to form blood pigments and aids in metabolism. The significance of glycine extends further as it participates in the synthesis of adenine and guanine - essential components of nucleic acids - while also being directly incorporated into proteins. Interestingly, scientists believe that glycine might have been one of the first amino acids to emerge on Earth during the era known as the primeval soup or primordial soup. This makes this microscopic image even more remarkable as it offers us a glimpse into our planet's ancient origins. Printed at 10 centimeters wide with a magnification level of x120, this photograph from Science Photo Library captures not only the scientific essence but also serves as a reminder of nature's intricate design at both macroscopic and microscopic levels.
