HLSC 2400U Study Guide - Midterm Guide: Carboxylic Acid, Glycogen, Disaccharide
Document Summary
Large carbon based molecules that carry but complex functions in living systems. Most contain oxygen, hydrogen, and nitrogen too. Our body consists of 55-60% water stored in intracellular space. Acids and bases relation to the ph scale. Acid is a proton donor and base is a proton acceptor. Acids and bases in order to maintain homeostasis the acidity of solutions in the body must be maintained. The number of the h+ ions determine a solution"s activity. Dissociation of an acid forms a h+ ion and a negative ion (anion) Dissociation of a base forms a hydroxide ion and positive ion (cation) Hydrogen and hydroxide ions join to form water. H+ ions are removed from the solution. 7 is neutral >7 is basic (alkaline) <7 is acid. Systems that resist change in ph of body fluids. They are three body systems that work together to maintain normal ph range. Medium: lungs excrete acids in the form of co2.
