August 2‚ 2013 Protein Article Research Proteins are molecules that consist of amino acids. Our skin‚ muscles‚ bones and other parts of the body depend on these amino acids to help our bodies function properly. Enzymes‚ hormones and antibodies are proteins. Proteins work as neurotransmitters‚ and protein carries oxygen in the blood and throughout the rest of the body. Amino acids are the building blocks for proteins. Enzymes‚ hormones‚ transport proteins‚ Immunoglobulin or Antibodies

more protein than meat-about two and a half times more than eggs‚ and far more than any other vegetable food except soybean and yeast. The proteins in groundnut are well balanced‚ except for slight deficiency in some of the essential amino acids. As it happens‚ these amino acids are‚ abundant in milk which can be combined with groundnut products for better results. For proper digestion‚ groundnut requires thorough mastication. Experiments made with the groundnut show that it is quite indigestible

flour’s water soluble components and therefore separating gluten from it. The isolated gluten was then used in different qualitative colour reaction tests. These tests determine what amino acids are present in a protein‚ in this case gluten. Introduction: Proteins are large biological molecules that are made up of amino acids. They serve as building blocks that form organic structures such as tendons‚ muscle‚ and cartilage. Enzymes - biological catalysts that allow important chemical reactions to occur

of this DNA is able to control the whole organism. With out DNA and its ability to make protein the cells and eventually the whole organism would die because it would not be able to reproduce protein. Protein is made out of a long chain of amino acids. It is made in cytoplasm of the cells. Protein synthesis is dependant of the DNA being properly decoded. To start the process of protein synthesis a section of the DNA " unzips " exposes the base sequence on the decoding strand. However

Neurotransmitters Neurotransmitters are chemicals made by neurons and used by them to transmit signals to the other neurons or non-neuronal cells (e.g.‚ skeletal muscle; myocardium‚ pineal glandular cells) that they innervate. The neurotransmitters produce their effects by being released into synapses when their neuron of origin fires (i.e.‚ becomes depolarized) and then attaching to receptors in the membrane of the post-synaptic cells. This causes changes in the fluxes of particular ions across

fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. The main role of phospholipids is that they can form lipid bilayers. It is an amphipathic molecule. The head which is hydrophilic contains a group of phosphate‚ a diglyceride and a simple molecule e.g. choline. The tail is hydrophobic and is made up of fatty acids. Phospholipids receive and transmit signals across the cell membrane and act as a store room for energy. Fatty acids Fatty
