HIV/AIDS The world is plagued by the HIV infection which almost always comes before AIDS. If you are HIV positive‚ that doesn’t mean you have AIDS. Having AIDS usually means that you are HIV positive. HIV (Human Immunodeficiency Virus) basically breaks down your immune system until it can’t function properly anymore. AIDS (Acquired Immune Deficiency Syndrome) never really kills anyone; instead it is a disease like pneumonia or something like that‚ that the body cannot fight because its immune system

AIDS is the sixth leading cause of death among people ages 25 – 44 in the United States. Millions of people around the world are living with HIV/AIDS‚ including many children under age 15 (PubMed Health). In addition‚ AIDS ranks the first leading of death in Vietnam.

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

EXPERIMENT 2: Recrystallization and Melting Point Recrystallization (or Crystallization) is a technique used to purify solids. This procedure relies on the fact that solubility increases as temperature increases (you can dissolve more sugar in hot water than in cold water). As a hot‚ saturated solution cools‚ it becomes supersaturated and the solute precipitates (crystallizes) out. In a recrystallization procedure‚ an impure (crude) solid is dissolved in a hot solvent. As this solution is cooled

Standardization of NaOH and Determination of Unknown Acid KEYWORDS: quantitative analysis‚ titration‚ buret‚ endpoint‚ standardization‚ half-equivalence point‚ calorimetric titration‚ potentiometric titration ABSTRACT: The concentration of sodium hydroxide was determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration

A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+) donors. They are the most common type of organic acid. Among

throughout the body with the majority found in the central nervous system. Neurones are specialized to process information in the body. Neurones convey this information to one another through the stimulation of a detector neurone. This causing a brief change in the electrochemical gradient resulting in the neurone moving away from its resting potential. This is known as an action potential. Once initiated the action potential travels the length of the axon reaching the pre-synaptic terminal where the
