Energy Production The reason that we eat, besides the fact that food can be so delicious, is for energy and building blocks. Although energy cannot be created or destroyed, its form can change. During metabolism, our bodies break down fuel molecules and trap the energy released within the molecule adenosine triphosphate (ATP).

· Following a steep contraction in 2020, chemical industry employment rebounded in 2021, although this was tempered somewhat by weatherrelated production curtailments. The industry gained a net 2,500 jobs in 2021, bringing employment to 532,000 (Figure 3). Stronger momentum in 2022 will result in another 10,000 jobs.

In fact, just reading the composition of any common cosmetic can become a chemistry class: water, emulsifiers, preservatives, thickeners, pH stabilizers, dyes and fragrances, combined in different ratios, for different purposes. The use of cosmetics – that is, chemical compounds to improve our appearance – is not a recent phenomenon.
From the relationship E = hc / λ, we see that longer wavelength visible light (400 to 800 nm) is less energetic (70 to 40 kcal/mole) than light in the accessible shorter wavelength (200 to 400 nm) near ultraviolet region (150 to 70 kcal/mole). Consequently, ultraviolet light is most often used to effect photochemical change.

Why chemicals matter. Chemicals are part of modern life, and we are likely to encounter them everyday from the chemicals used at work, to products in the home such as paint, and detergents and pesticides used in the garden. This website aims to guide you to the information you need to help you identify and manage the risks from chemicals.
CMC – Chemistry, Manufacturing and Controls To appropriately manufacture a pharmaceutical or biologic specific manufacturing processes, product characteristics, and product testing must be defined in order to ensure that the product is safe, effective and consistent between batches.
