Biochemistry

tier

Biology; Biochemistry

The cohort of chains of a branched-chain polysaccharide that all have the same relationship to the branch points. The outer tier of glycogen is all those glucosyl units that are attached in α1→4 ...

core protein

Biology; Biochemistry

One of the proteins to which are attached the carbohydrate chains (e.g. chondroitin sulphate, keratan sulphate) of a proteoglycan, and which with them comprise the subunits of the proteoglycan.

linkage disequilibrium

Biology; Biochemistry

In genetics, the more-frequent-than-random occurrence together of two genetic loci within an individual. This may be due to their proximity on the same chromosome, to selective pressure on their ...

In genetics, the more-frequent-than-random occurrence of two traits together due to their proximity on the same chromosome. The likelihood of a recombination event separating the two traits decreases ...

glycoconjugate

Biology; Biochemistry

A compound composed of an oligosaccharide linked to a protein or lipid, e.g. mucins (which are glycoproteins), globosides (which are N-acetylsphingosine conjugates of oligosaccharides), and the ...

transforming factor

Biology; Biochemistry

In the classical experiments by Avery, MacLeod and McCarty, the name given to the agent that caused the heritable transformation of R strains of Streptococcus pneumoniae into S strains. The ...

human leucocyte antigen (HLA)

Biology; Biochemistry

An antigen on the surface of human cells that consists of a generally invariant β 2 -microglobulin and a larger polypeptide chain that is characteristic of the individual; responsible for most cases ...
