different emotional responses and also control the level of pain a person may be feeling. Endorphins have been found to control the level of activity within a person’s nervous system. These neurotransmitters‚ that have been found to be chains of amino acids‚ inhibit the neuron’s ability to transmit the sensation of pain and thus reduce the body’s overall feeling of pain. In the example of athletes‚ endorphins can give people the feeling of a runner’s high. There are a multitude of different chemicals

Introduction Since the beginning of time‚ the body has been a sign of dominance. Creatine monohydrate has been around for over a hundred years‚ but it has been only used as a dietary supplement for the past decade. Over the years creatine has been one of the leading in supplements‚ and it is used worldwide. Creatine is neither a drug nor a steroid; it is a legal dietary supplement. Athletes use it to get the edge on competition and older people use it to stay healthy. It all depends on who

Abstract Diferulic acid forms cross-links in naturally occurring plant cell wall polymers such as arabinoxylans and pectins. We have used model ethyl esterified substrates to find enzymes able to break these cross-links. A tannase from Aspergillus oryzae exhibited esterase

Q 1. In this practical exercise you will be using biuret reagent. Why is biuret reagent used in this practical? The biuret reagent is used to assess the concentration of the protein because peptide bonds occur with the same frequency per amino acid in the peptide. The intensity of the colour‚ and therefore the absorption‚ is directly proportional to the protein concentration. Q 2. What is the experimental reason for constructing a standard curve? Multiple samples with known properties

Structural Analysis of Serine Peptidase-Inhibitor Complexes When analyzing these structures‚ we observed a reasonably strong hydrogen bond interaction (distance ~ NVL ≫ AAoF ≈ NVoL. Surprisingly‚ the unmodified AAF compound showed a substantially higher level of activity over the unmodified NVL compound. Initially‚ we hypothesized that the modified compounds (No H-Bond) would be less active. To our surprise‚ both modified compounds‚ AAoF and NVoL‚ showed negligible activity (Figure 16). Additionally
