Upper left panel, Electrical signals are recorded from a Xenopus oocyte expressing the circadian photoreceptor melanopsin in response to illumination with blue light. Upper right panel, Photocurrent recorded from an oocyte expressing melanopsin and the TRPC3 ion channel in response to illumination at various wavelengths. Peak activation of melanopsin signaling occurs at about 470 nm, which corr...

Soil biochemistry is one of the branches of soil science dealing with the formation and decomposition of soil organic matter, biochemical reactions of carbon, nitrogen, phosphorus, sulfur, metals and xenobiotics in soils, and biochemistry of the plant-root rhizosphere. This chapter is divided into eleven sections, the first of which provides a definition of soil biochemistry and its scope of in...

Transporter proteins bind ions and small molecules and transfer them across lipid membranes. Recent studies on transporters, discussed in this issue's Biochemistry Select, provide insight into the family of proteins targeted by tricyclic antidepressants. Other work sheds light on glucose absorption in the gut, host-pathogen interactions , and a mechanism used by an important food crop to adapt ...

Students being trained as dietitians or public health nutritionists will work with an assortment of populations that differ by demographics such as age, gender, and socioeconomic status. As such, these students must gain a wide scope of knowledge to develop their understanding of the nutritional needs across populations and the life cycle. Accredited nutrition programs offer courses to students...
