The basic structure of all the penicillins consists of a thiazolidine ring fused with a beta-lactam ring‚ creating a fundamental nucleus (also known as 6-amino penicillanic acid) crucial for their antibacterial activity. A wide variety of semisynthetic penicillins are produced by altering the composition of the side chains attached to this nucleus.The molecular formula of penicillin is C16H18N2O4S and weight of 334.39 g/mol‚ each base with a variable side chain‚ “R” that differentiates the penicillins

The 3 Basic Types of Descriptive Research Methods One of the goals of science is description (other goals include prediction and explanation). Descriptive research methods are pretty much as they sound — they describe situations. They do not make accurate predictions‚ and they do not determine cause and effect. There are three main types of descriptive methods: observational methods‚ case-study methods and survey methods. This article will briefly describe each of these methods‚ their advantages

the participants are in and the researchers do nothing to change the behavior of the participants. Natural observation is used when researchers are looking for a particular behavior but this can be a very time consuming method of research. The researcher has no guarantee that he or she will witness the particular behavior he or she is looking for.
