Lipofuscin is the name given to fine yellow-brown pigment granules composed of lipid-containing residues of lysosomal digestion and considered to be one of the aging or “wear-and-tear” pigments

Lipofuscin is the name given to fine yellow-brown pigment granules composed of lipid-containing residues of lysosomal digestion.[1][2] It is considered to be one of the aging or “wear-and-tear” pigments, found in the liver, kidney, heart muscle, retina, adrenals, nerve cells, and ganglion cells.[3] Formation and turnover Lipofuscin appears to be the product of the oxidation of unsaturated fatty acids and may be symptomatic of membrane damage, or damage to mitochondria and lysosomes. Aside from a large lipid content,…

What Is A Siderophore?

Siderophores (Greek: "iron carrier") are small, high-affinity iron-chelating compounds that are secreted by microorganisms such as bacteria and fungi. They help the organism accumulate iron. Although a widening range of siderophore functions is now being appreciated. Siderophores are among the strongest (highest affinity) Fe3+ binding agents known. Phytosiderophores are siderophores produced by plants.

Structural motif

In a chain-like biological molecule, such as a protein or nucleic acid, a structural motif is a common three-dimensional structure that appears in a variety of different, evolutionarily unrelated molecules. Johansson, M.U. (23 July 2012). “Defining and searching for structural motifs using DeepView/Swiss-PdbViewer”. BMC Bioinformatics. 13 (173): 173. doi:10.1186/1471-2105-13-173. PMC 3436773. PMID 22823337. A structural motif does not have to be associated with a sequence motif; it can be represented by different and completely unrelated…
