21 Νοε 2023 · In chemistry, the solution is a mixture of one or two substances. Not just any mixture is a solution. Solutions must be a homogenous mixture. Homogenous means that it has a uniform structure....
Chemistry provides an understanding of the molecular structure of amino acids and how they bond to make proteins. This helps explain amino acid deficiency diseases like kwashiorkor, that biologists have characterized, and helps nutritionists design healthy diets for vegetarians, athletes, and new mothers.
19 Ιουν 2023 · Solution concentration plays critical roles in biology: Differing concentrations of hydrogen ions on opposite sides of a membrane provide the driving force for synthesis of ATP, as shown by an animation.
In aqueous solution, amino acids are not neutral (left), but are zwitterionic (right) where the amino group is protonated and the carboxylic acid group is deprotonated. All amino acids with the exception of glycine (R = H) are chiral.
28 Απρ 2017 · A solution can be liquid, solid, or gaseous. Further, a solution can be a mixture of liquids, gases and solids. In some cases, like seawater, the solution consists of a great many different types of solutes, like salts, oxygen, and organic molecules. Types of Solution. Polar and Nonpolar Solutions.
Life originally evolved in a watery environment, and most of an organism’s cellular chemistry and metabolism occur inside the watery contents of the cell’s cytoplasm. Understanding the characteristics of water helps to elucidate its importance in maintaining life.
