of every life form, composed of 20 or more amino acids linked in one or more long chains, the final shape and other properties of each protein being determined by the side chains of the amino acids and their chemical attachments." The term protein derives from the Greek prote, or primary...
Explain why cellular proteins are composed of amino acids as their building blocks Explain how the shapes of carbohydrates, lipids, and proteins relate to their functions. Describe the importance of shape in the functioning of a protein...
During protein synthesis, amino acids are linked together in a specific order. The amino acid chain, called a polypeptide, then folds into a three dimensional shape to make a functional protein. Proteins are important components of body structures, such as bone, hair, nails and muscle. However...

One of the most important functions of living cells is to produce the proteins necessary for an organism’s survival. Proteins give shape and structure to an organism and, as enzymes, regulate biological activity. To manufacture proteins, a cell needs to
Why are proteins important in your body and how to make a protein from DNA? Summarize how DNA and RNA differ in structure and function. What are the properties of DNA that allow it to function as genetic material? Describe the observations of the extracted DNA obtained. How thes...
S-palmitoylation is a reversible posttranslational protein modification, whereby palmitic acid forms a thioester bond with the sulphur atom of particular cysteine residues in target proteins. How is it relevant to oncology? Oncology includes the study of tumour formation. Dysregulation of Spalmitoylation...
This creates the need for updated discriminatory diagnostics for quick and accurate identification of the pathogen(s). While capripoxviruses and orthopoxviruses can be differentiated from parapoxviruses by electron micro- scope based on the differences in their shape, such a differentiation cannot be ...
Structural genomics projects aim to solve the experimental structures of all possible protein folds. Such projects entail a conceptual shift from traditional structural biology in which structural information is obtained on known proteins to one in which
A newly discovered small protein in mitochondria is essential for energy production, report Duke-NUS researchers and their colleagues in the journal Nature Communications. Zebrafish lacking the small protein, which the scientists named BRAWNIN, have simi
