Medical Biochemistry at a Glance
Samenvatting
Offering a concise, illustrated summary of biochemistry and its relevance to clinical medicine,
Medical Biochemistry at a Glance is intended for students of medicine and the biomedical sciences such as nutrition, biochemistry, sports science, medical laboratory sciences, physiotherapy, pharmacy, physiology, pharmacology, genetics and veterinary science. It also provides a succinct review and reference for medical practitioners and biomedical scientists who need to quickly refresh their knowledge of medical biochemistry.
The book is designed as a revision guide for students preparing for examinations and contains topics that have been identified as ′high–yield′ facts for the United States Medical Licensing Examination (USMLE), Step 1.
This third edition:
Has been thoroughly revised and updated and is now in full colour throughout
Is written by the author of the hugely successful Metabolism at a Glance (ISBN 9781405107167)
Features updated and improved clinical correlates
Expands its coverage with a new section on Molecular Biology
Includes a brand new companion website of self–assessment questions and answers at www.ataglanceseries.com/medicalbiochemistry
