A Level Biology Revision "Fibrous Proteins Collagen, Keratin and Elastin" 

You can find all my A Level Biology videos fully indexed at www.freesciencelessons.co.uk/...
In this video we explore the structures and functions of fibrous proteins. We start by comparing the general structure of fibrous proteins with globular proteins. We then look at the structures and functions of three fibrous proteins: collagen, keratin and elastin.
