Applications of Proteins in Daily Life

Proteins are large complex molecules that are made up of hundreds or thousands of smaller units of amino acids which are attached forming long chains. The sequence of these amino acids determines each protein’s unique 3-dimensional structure and its specific function. Amino acids are coded by combinations of three DNA building blocks which are nucleotides. They are large biomolecules and macromolecules that perform a vast array of functions within organisms, including catalyzing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. Most microorganisms and plants can biosynthesize all 20 standard amino acids, while animals (including humans) must obtain some of […]

Importance of Proteins For the Body

Food holds the main portion of nutrition we acquire for our body. Hence consumption of the right amount of them is essential. As the generations passed, the healthy eating habits have reduced which resulted in people being more conscious about their health leading to different kinds of diets. However, these dietary habits might help in losing weight but at the same time makes the body deficient in essential nutrition. Proteins are the building blocks of life. They are polymers of amino acids linked via alpha peptide bonds. They can be represented as primary, secondary, tertiary, and quaternary structures. But from a nutritional viewpoint, only primary proteins are considered. Similarly, although many compounds in the body can be chemically defined as amino acids, we are only concerned with the 20 canonical amino acids encoded in DNA, plus 5 others—ornithine, citrulline, γ-aminobutyrate, β-alanine, and taurine—that play quantitatively important roles in the body.

Nutrients And Their Importance For Human Body

Nutrients are components that are essential to life and health providing the body with energy and components of repair and life support. The varieties of enriched components of nutrients can include proteins, vitamins, fats, minerals, and carbohydrates. Just like every other component in our body, not all the nutrients provide energy but are necessary for many other functions. Hence based on this, nutrients are divided into two broad categories; Macronutrients which are required by our body in large amounts, and micronutrients which are required by our body in small amounts. The consumption of dietary nutrients applies to animals, plants, fungi, and protists. They are incorporated into cells for metabolic purposes or excreted by these cells to create other essential components such as hairs, scales, feathers, or exoskeletons. Some nutrients are metabolically converted into smaller molecules in the process of releasing energy, such as carbohydrates, lipids, proteins, and fermentation products which […]

Essential Fats For Human Body | Functions of Fat In Body

Often considered unhealthy, fats are an important aspect of essential nutrients just like vitamins, carbohydrates, and proteins. Dietary fats are important for several health-related aspects and in the optimal functioning of the human body. They are not just a source of energy, they are the building blocks of the body that carry many fat soluble nutrients. It overall contributes to the growth and development of the body. The Good Fat Fat as the name suggests does produce an increasing amount of fat deposition in the body tissues if not consumed efficiently. There are certain essential fats required by the body in certain amounts, anything above that particular quantity or kind can result in deposition of adipose fat, high cholesterol, and many other diseases. Fat supplies essential fatty acids to our body. These are referred to as EFAs in short. The human body as it is cannot produce EFAs known as […]

Top 8 Cold Cases in America That Remains Unsolved Till Date

High Performance Thin Layer Chromatography (HPTLC)

High performance Thin layer chromatography(HPTLC) is a sophisticated form of Thin layer chromatography. It provides superior separation efficiency. The concept of HPTLC includes validated methods for qualitative and quantitative analysis and fulfills all requirements to be used in the fully-fledged environment. It is also known as planar or flatbed chromatography. A particular advantage of this technique is that it can be combined with mass spectrometric approaches, thus allowing detailed structural characterization of carbohydrate and ceramide moieties. Furthermore, HPTLC can be easily used in the context of so-called overlay techniques Principle of HPTLC HPTLC possesses a similar principle to that of Thin-layer chromatography(TLC) which is principle of adsorption chromatography. The solvent used in the mobile phase flows due to capillary action and the component moves according to their affinity towards adsorbent and eluent. The component with more affinity towards the stationary phase travels faster and the component with less affinity towards […]

Boston Strangler Case Solved After 50 Years Using DNA Analysis

Mary Sullivan, a 19-year-old who lived in Beacon Hill apartment across Tony Charles street in Boston was found raped and murdered at the apartments around 1967.

Quantification of DNA From Forensic Exhibits

Deoxyribose nucleic acid(DNA) as we know holds the blueprint of every individual’s character and traits. When it comes to forensic science, DNA is worth a million gold for the scientists who analyze the sample. Multiple criminal and civil cases across the globe were solved due to this miraculous invention.  Edmond Locard gave Locard’s principle of exchange in forensics stating every contact leaves a trace. When culprits leave the crime scene, they tend to shed evidence without their knowledge. Now, this could include their bodily cells or any kind of body fluids. These samples hold a huge amount of DNA traces. This biological material can also end up being contaminated if not properly collected and packed from the crime scene. Sources of DNA DNA can be extracted mostly from biological evidence. However, few physical evidence like fabrics or any kind of surface could hold this biological evidence or even direct touch […]

Christopher Mhlengwa Zikode: South African Serial Killer & Rapist

Donnybrook, a tiny village in South Africa rich with its tribal cultures and traditions where one such tradition includes faction fights.

He even learned how to use modernized guns during the fight. His father taught him all sorts of defense artworks along with a detailed course on how to kill a human clean. Never did he know that his son would turn into an […]

Top 5 Cases Solved Using Biological Evidence in the United States

Any material obtained from a crime scene or any place associated with a particular crime, victim, or suspect that is biological in nature is considered biological evidence. It can include hair strands, fibers, any plant or animal materials such as tissues, or even body fluids like blood, semen, and saliva. Evidence, once encountered, is sent for further analysis to the Forensic laboratory following a proper chain of custody. Biological pieces of evidence are usually sent to the Forensic Biology or serology division.  The typical crime scene scenarios that appear to people are from web series or movies. However, the real situation is quite different. Analysis of evidence does not produce results from superfast machines as seen in the fictional movie world, especially if it is an analysis of a DNA print. Biological evidence can be considered to have pretty much first preference in the chain of evidence, however, analysis of […]
