Biological functions of allantoin

Biology Bulletin, 2006
A historical review of allantoin research is presented. An increased allantoin level in the trophoblast and serum of pregnant women has been demonstrated. Allantoin concentration decreased in placental tissues and increased in the serum in developing placental insufficiency.

Biological functions of selenium

Trends in Biochemical Sciences, 1980
Current studies in a number of laboratories show that selenium is a normal component of at least one mammalian enzyme, several bacterial enzymes and certain bacterial tRNAs. In three of the enzymes selenium is present in the chemical form of selenocysteine residues.

Biological functions of sphingomyelins

Progress in Lipid Research, 2013
Sphingomyelin (SM) is a dominant sphingolipid in membranes of mammalian cells and this lipid class is specifically enriched in the plasma membrane, the endocytic recycling compartment, and the trans Golgi network. The distribution of SM and cholesterol among cellular compartments correlate.

The biological functions of microcystins

Water Research
Microcystins are potent hepatotoxins predominantly produced by bloom-forming freshwater cyanobacteria (e.g., Microcystis, Planktothrix, Dolichospermum). Microcystin biosynthesis involves large multienzyme complexes and tailoring enzymes encoded by the mcy gene cluster. Mutation, recombination, and deletion events have shaped the mcy gene cluster in the

Biological Function of Prokineticins

2008
Secreted peptides have been implicated in diverse physiological functions. Prokineticins are a pair of regulatory peptides that signal through two highly homologous G protein-coupled receptors. Prokineticins possess a unique structural motif of five disulfide bonds and conserved N-terminal stretches.

MEMORY AS A BIOLOGICAL FUNCTION

American Journal of Psychiatry, 1953
From these reflections it appears that memory is a basic attribute of all living things, by which patterns of sensitivity and response, both inborn and acquired, are retained and progressively modified under the impact of experience. Memory is thus indispensable in all behavior, making it at once consistent and modifiable.

Lactoferrin and Its biological functions

Biochemistry (Moscow), 2001
Lactoferrin, a component of mammalian milk, is a member of the transferrin family. These glycoproteins transfer Fe(3+) ions. Lactoferrin is a unique polyfunctional protein that influences cell proliferation and differentiation. It can regulate granulopoiesis and DNA synthesis in some cells.

Biological applications of functionalized calixarenes

Chem. Soc. Rev., 2013
The functionalized calixarene derivatives exhibit remarkable properties towards organic and bioorganic molecules. However, the ability of calixarene derivatives to form stable complexes with biomolecules allows them to be applied for the development of biosensors and in the field of biology, biotechnology, and drug discovery.

Biomimetic Coatings and Their Biological Functionalization

2008
The biomimetic coating technique can be used to deposit layers of calcium phosphate (CaP) on medical devices to improve their osteoconductivity and osseointegration.The inorganic layer generated is akin to mineralized bone matrix and can be degraded as such.
