New system improves the quality of frozen horse sperm

Cryopreservation is a freezing method of storing spermatozoa to be used for reproduction. Although it is widespread, there is an issue with the ice formation that occurs during the process, which ends up affecting sperm structure ...

Producing handy gels from a protein found in human blood

The protein albumin is responsible for many vital processes in the human body. In nature, it only appears as a solution when dissolved in water. Chemists at Martin Luther University Halle-Wittenberg (MLU) have developed a ...

Too-few proteins prompt nanoparticles to clump

Blood serum proteins have been observed combining one-to-one with gold nanoparticles and prompting them to aggregate, scientists at Rice University reported.

The case of the sticky protein

Proteins are like a body's in-house Lego set. These large, complex molecules are made up of building blocks called amino acids. Most of the time, proteins fold correctly, but sometimes they can misfold. This misfolding causes ...

Scientists reduce sweetener stevia's bitter bits

Good news for consumers with a sweet tooth. Cornell food scientists have reduced the sweetener stevia's bitter aftertaste by physical – rather than chemical – means, as noted in the Oct. 14 issue of the journal Food Chemistry.

Albumin

Albumin (Latin: albus, white) refers generally to any protein that is water soluble, which is moderately soluble in concentrated salt solutions, and experiences heat denaturation. They are commonly found in blood plasma, and are unique to other plasma proteins in that they are not glycosylated. Substances containing albumin, such as egg white, are called albuminoids.

A number of serum transport proteins are known to be evolutionarily related, including serum albumin, alpha-fetoprotein, vitamin D-binding protein and afamin.
