1.4.4 Covalent cross-linkages stabilise protein structure

Proteins that are secreted by the cell, or are attached to the extracellular surface of the plasma membrane, can be subject to more extreme conditions than those experienced by intracellular proteins. Often, covalent cross-linkages stabilise these proteins by connecting specific amino acids within a polypeptide or between polypeptide chains in multisubunit proteins (see below). Typically such a linkage will be a covalent sulfur–sulfur bond which forms between the –SH groups of two cystein

Orphan Works 4: Types of Works Subject to Any Orphan Works Legislation
As described in the Office's previous Notice and many of the responding comments, orphan works remain a pervasive issue in copyright law. While the issue cuts across all creative sectors, the unique challenges posed by photographs have long been an obstacle to developing an effective orphan works solution. Photographs and other works of visual art may lack or may more easily become divorced from ownership information, especially in the age of social media that has largely transpired since Congre

2.3 Wales

In 1282, Edward I conquered Wales and the Statute of Rhuddlan (or Statute of Wales, 1284) established English rule. Rather than involve the assimilation of the Welsh by the English the conquest saw ‘a colonial system … established in those parts of Llywelyn's Principality which were by 1284 in the hands of the king’ (Davies, 1991, p. 166). In 1400, Owain Glyndwr led the most outstanding and successful rising in Wales against the new order and the tyranny of the English border barons, wh

3.1 Features of the diving response

All the aquatic mammals' adaptations to life in the water - breathing, moving, staying warm and making sense of the environment - come together in their diving behaviour, and the diving abilities of marine mammals are truly awe-inspiring. The elephant seal, for example [p. 192], makes repetitive, long-duration dives and some 80-95% of its time at sea is spent submerged. Its dives are of about 20 minutes duration on average, and the intervals at the surface are seldom more than about two minut

Introduction

In this unit you will learn how advances in genetics could change the way in which diseases are diagnosed and managed. The advent of predictive medicine, based on more detailed DNA profiling of individual genotypes using technologies like gene chips, rather than screening for one gene at a time, may shift the relationship between doctor and patient. People will be seeking advice on how to manage their susceptibilities or genetic risks, rather than looking for treatment for an already existing
