So basically Proteins are basic constituents in all living organisms. They are complex molecules composed of amino acid and necessary for the chemical processes that occur in living organisms. Proteins are sometimes referred to as macromolecular polypeptides because they are very large molecules and because the amino acids of which they are composed are joined by peptide bonds. The vast majority of the proteins found in living organisms are composed of only 20 different kinds of amino acids, repeated many times and strung together in a particular order. Each type of protein has its own unique sequence of amino acids.

Despite the fact that HSV replicates successfully in humans, they found that it was not as successful replicating in many Old World primates, particularly the rhesus macaques monkeys. The purpose of this journal is to try to gain a better understanding of why the rhesus macaques have the ability to resist to HSV and to, then, apply the knowledge to help better treat herpes and other viral infections in humans. In order to justify the hypothesis, a variety of tests were carried out using sophisticated techniques. Figure 1 displays a pair of line graphs that represent the quantitative viral growth differences between the rhesus monkey and HeLa cells while incubated at optimal conditions. It was revealed that there was a significant fold reduction in HSV-infected rhesus cells in contrast to the HeLa cells control. Figure 3 shows that the cells of the Old World primates i. African green monkey and the rhesus monkey had a significantly lower amount of viral replication than the New World primates i.
Cathy Logan, 27, Goshen, New York. Once I chose the course as I thought it was interesting, but in a month, I was upset that it will not cover the topics that were the most interesting for me. So, I decided to order the papers on this website to finish the course. Good service for good money.

Proteins The word protein originates from the Greek word protos which denotes "the first rank of importance", in all biological systems we find macromolecules called proteins which range from as low as prokaryotes to higher eukaryotes. Naturally proteins are complex in nature performing numerous functions that sustain life. Proteins are primarily considered to have one primary function to serve its role in an organism, however studies have observed to have multiple functioning proteins known as moonlighting proteins Khan et al. Moonlighting proteins along with primary functions, have secondary functions that are not related to the primary function and does not correlate to the primary or other functions Khan et al. The multifunctional proteins play essential roles in carrying out biochemical functions.

Protein consists of combinations of structures called amino acids that combine in various ways to make muscles, bone, tendons, skin, hair, and other tissues. They serve other functions as well including nutrient transportation and enzyme production. Various foods supply protein in varying amounts with complete proteins those containing 8 essential amino acids coming mostly from animal products such as meat, fish, and eggs and incomplete protein lacking one or more essential amino acid coming from sources like vegetables, fruit and nuts. Athletes need protein primarily to repair and rebuild muscle that is broken down during exercise and to help optimizes carbohydrate storage in the form of glycogen.
