Globoside is a type of glycosphingolipid, a complex molecule found primarily in the membranes of mammalian cells. It consists of a ceramide backbone (a lipid) attached to a terminal oligosaccharide (a sugar chain).
In this section we examine the structure of the DNA molecule and explain in general terms how it is able to store hereditary information. A DNA molecule consists of two long polynucleotide chains composed of four types of nucleotide subunits. Each of these chains is known as a DNA chain, or a DNA strand.
we look closely at the structure and chemistry of DNA in order to learn how its double-helical architecture allows information to be stored, duplicated, and accessed.
17 mar 2022 · Eukaryotes, whose chromosomes each consist of a linear DNA molecule, employ a different type of packing strategy to fit their DNA inside the nucleus (Figure \(\PageIndex{6}\)). At the most basic level, DNA is wrapped around proteins known as histones to form structures called nucleosomes.
21 sty 2021 · DNA (deoxyribonucleic acid) molecules are nucleic acids, which are the information-carrying molecules of the cell. DNA molecules are polymers and are made up of many smaller molecules, called nucleotides. Each nucleotide contains a phosphate group, a sugar molecule, and a nitrogenous base.
The anomeric structures of the remaining glycosidic bonds were assigned by glycosidase experiments [39,202] and NMR studies [74]. This established the whole carbohydrate structure of globoside: GalNAcβ1-3Galα1-4Galβ1-Glcβ1-Cer.
Globoside is an intermediate in the synthesis of more complex structures of the globo series of glycosphingolipids such as the Forsmann antigen, the stage-specific embryonic antigen 4 and globo-H.
