Chapter 19, Problem 12P
Summary Introduction

To explain: The reason why most proteins have less D-aspartate and elastin has increasing levels of D-aspartate steadily with age.

Concept introduction: Racemization is the process where the pure mixture of enantiomers is converted entirely into another form of enantiomer. L-aspartate in proteins is racemized to D-aspartate by racemization. Elastins are highly contractible proteins that can come back to their original state once the stress which causes the contraction is removed. Elastin is present in skin and connective tissue and is part of anchoring junction proteins.

Using information from the primary literature (several references have been provided as a starting point below) please answer the following question: Based on your review of the literature on rewilding, what are the major scientific pros and cons for rewilding?   Please note that the focus of this assignment are the (biological) scientific issues associated with rewilding. As will be discussed in class, there are a number of non-scientific issues involved or implicated in rewilding, all ultimately affecting the public acceptability of rewilding. Although these issues are important – indeed, critical – in this assignment you should focus on the biological science issues and questions.   Details: You must enumerate at least two pros and at least two cons. Your answer should be no more than 500 well-chosen words, excluding references. Think carefully about how best to organize and structure your answer. Aim for high information density: say a lot, but say it succinctly. Recall Nietzche’s…
