Using Physical Models of Biomolecular Structures To Teach Concepts of Biochemical Structure and Structure Depiction in the Introductory Chemistry Laboratory  Gordon A. Bain, John Yi, Mithra Beikmohamadi, Timothy M. Herman, and Michael A. Patrick
Custom-made physical models of alpha-helices and beta-sheets, the zinc finger moiety, beta-globin, and green fluorescent protein are used to introduce students in first-year chemistry to the primary, secondary, and tertiary structure of proteins.

Glycosyltransferases A and B: Four Critical Amino Acids Determine Blood Type  Natisha L. Rose, Monica M. Palcic, and Stephen V. Evans
Human A, B, and O blood type is determined by the presence or absence of distinct carbohydrate structures on red blood cells. In this review the chemistry of the blood group ABO system and the role of glycosyltransferase A, glycosyltransferase B, and the four amino acids critical to determining blood group status are discussed.

Testing for Ultraviolet Toxicity Using Fungi  Marcelo Vital and Patricia Esperón
In this article, we describe a laboratory project quantifying the effects of UV radiation on a suspension of living cells. This laboratory experiment was designed for undergraduate students in biochemistry. The experiment was carried out employing different fungi strains, changing the dosage of radiation, the distance to the UV source, and the exposure period to the UV radiation. The quantity of viable spores was calculated and the dose¬Ěresponse curves were drawn. Students were able to prove that 100% of mortality was achieved with the longest time of exposure.

Analysis of DAPI and SYBR Green I as Alternatives to Ethidium Bromide for Nucleic Acid Staining in Agarose Gel Electrophoresis  Kevin M. Bourzac, Lori J. LaVine, and Margaret S. Rice
DAPI and SYBR Green I are good staining alternatives to ethidium bromide in that they have similar sensitivity and are both easy to use. SYBR Green I is more expensive than EB or DAPI; however, the limited safety data suggest that SYBR Green I is the safest stain.

An Attack on the AIDS Virus: Inhibition of the HIV-1 Protease. New Drug Development Based on the Structure and Activity of the Protease and its Role in the Replication and Maturation of the Virus  Volker, Eugene J.
Article shows how research into the biochemistry of HIV may lead to a method for controlling its growth and maturation. This research illustrates some basic enzyme chemistry and holds student appeal due to the tie into current affairs.
