Protein

Functions of Proteins in Living Organisms Proteins are an essential part of a healthy diet in the human body which help to stimulate growth and maintenance. They are made up of amino acids, which the body uses to make new protein for a huge variety of functions. Proteins work as a power source which is said to be the bodies tissue building blocks. Protein is needed to form blood cells. Protein assists in shaping the hair, nails and muscles which are the structural features of the body. Structural

Proteins are the metabolic workhorses of the cell; they engage in a variety of essential activities ranging from enzymatically catabolizing macromolecular food sources to serving as structural components that maintain cell stability. Maximizing protein function relies on intricate non-covalent interactions occurring on the secondary, tertiary, and quaternary levels that help determine the overall shape of the protein. In their native states, proteins will assume the most energetically favorable

Proteins are the building blocks of the cells. Without them our cells would not have the genetic code they need to build up our bodies. Proteins are synthesised or made in the ribosome with the help of DNA and RNA. DNA is a double helix, or a twisted ladder shape, found in the nucleus and contains the genetic code for organisms. RNA is found in the nucleus or in ribosomes and is composed of the nucleotides ribose, phosphate group, and nitrogenous base. While in the nucleus, the RNA copies the genetic

Genes expression is what encodes many proteins to give function to a cell. It involves many steps that mostly include transcription and translation. Transcription alone does not play a role in gene expression (Erster Lect. 24). There are many post-transcriptional regulatory mechanisms that have been found to be involved. These mechanisms are a part of RNA processing. One of this can occur through alternative splicing. This is when exons of the same gene are spliced together to produce different mRNA

1- How would you evaluate the protein status of children with PEM? Which markers would you use and what are the expected results? The protein status of children with protein energy malnutrition (PEM) can be assessed by complete patient history and physical examination in which the skin would appear thinner and dull/discolored, hair growth is restarted and hair may fall and there would be loss of lean body mass over long period of time (Stipanuk and Caudill). The WHO recommends laboratory tests of

Gene expression is the process of protein formation. Proteins are the molecules that are responsible for enabling us to live. They carry out majority of the processes that are important for life, as they include enzymes, transcription factors and the various cell machinery. Indeed, without proteins, life may not be a possibility. Gene expression cannot be carried out without a nucleic acid sequence, also known as DNA in humans. DNA is a double stranded molecule comprising of a sugar-phosphate backbone

Protein Denaturation-an Important Concept in Biology! Biology has many topics which unfold the truths of nature in an interesting way. Protein denaturation is one such topic which shows how denaturation of protein is found in common household activities like cooking. What are proteins? Proteins are found in all living beings. They are large molecules which are composed of folded amino acid chains. Every protein has its unique shape and functions based on its shape. Proteins are like keys that fit

The Structure of Proteins Introduction Campbell and Farrell define proteins as polymers of amino acids that have been covalently joined through peptide bonds to form amino acid chains (61). A short amino acid chain comprising of thirty amino acids forms a peptide, and a longer chain of amino acids forms a polypeptide or a protein. Each of the amino acids making up a protein, has a fundamental design that comprises of a central carbon or alpha carbon that is bonded to a hydrogen element, an amino

Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary, secondary, tertiary, and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from

among other things, protein degradation through the ubiquitin-protease system (UPS) and the consolidation and reconsolidation of long-term fear memories. This research was necessary because, while research had been done linking protein degradation to synaptic plasticity, no study had been performed to analyze the role of UPS in the amygdala, where long-term fear memories are believed to be stored. Additionally, prior research had led to conflicting reports of the importance of protein degradation in consolidation
