Introduction Chemistry: Chemistry is the science of matter‚ especially its chemical reactions‚ but also its composition‚ structure and properties. [pic] Daily Life: All the things that happen or that you do regularly. Chemistry in Daily Life: Chemistry is a big part of our everyday life. We find chemistry in daily life in the foods we eat‚ the air we breathe‚ our soap‚ our emotions and literally every object we can see or touch. Here’s a look at some everyday chemistry.

Flavored water From Wikipedia‚ the free encyclopedia Flavored water is a beverage consisting of water with added natural or artificial flavors‚ herbs‚ and sweeteners‚ and is usually lower in calories than non-diet soft drinks. In many cases‚ flavored waters add vitamins and minerals to their beverages through the incorporation of fruits in order to better market their products. Pepsi and Coca-Cola are two well known brand owners of flavored water but there are many others as well. Flavored water

In the next step in aerobic respiration‚ each pyruvate‚ as produced by glycolysis in the cytosol‚ is normally converted to acetyl-CoA by pyruvate dehydrogenase in the mitochondria. During this process‚ electrons are transferred to NAD+‚ producing NADH‚ and a carbon is lost in the form of CO2 as a product. Acetyl-CoA then goes through another series of reactions in the TCA cycle‚ all of which also occurs in the mitochondria‚ to generate ATP and NADH through the complete oxidation of the molecule (generating

NST Exam 2 Study Guide! I. Proteins Function of body protein: antibodies in the immune system‚ muscle contraction and movement‚ enzymes that facilitate biochemical reactions (catalysts)‚ hormones that regulate bodily activities‚ structural proteins that provide support‚ such as with keratin and collagen‚ found in connective tissues‚ storage proteins store amino acids‚ transport proteins carry molecules/nutrients from one place to another (i.e. hemoglobin). Also contributes to acid base balance

consist mainly of various proteins and lipid molecules. The amphipathic phospholipid molecule is the major component of the bilayer membrane (Figure 4.1). Figure 4.1: The structure of a phospholipid molecule‚ the basic component of a membrane bilayer. Due to its composition the phospholipid bilayer will allow only the passage of small hydrophobic or uncharged molecules (Figure 4.2). The passage of large or charged molecules is hindered by the lipid bilayer. Their passage through the cell

Zinc‚ Iodine‚ Iron‚ Magnesium‚ Calcium and Chromium. Zinc is an essential mineral found in cells throughout the body. It plays an important role in the immune system‚ wound healing‚ and the breakdown of carbohydrates and lipids. Its main functions are the DNA synthesis‚ metabolism of protein‚ development of sexual organs and bones‚ cell division and growth. Animal food that’s is protein rich food is also rich in zinc such as beef‚ poultry‚ and milk‚ nuts‚ whole grains‚ legumes‚ and yeast. This is
