The retinoids, a group of molecules related to the dietary retinol (vitamin A) , are essential for vision and reproduction,
Because the body is complex, energy is required to ensure proper functioning. Adenosine triphosphate, or ATP, is the energy source for use and storage at cellular level. ATP's structure is a nucleoside triophosphate. It consists of a ribose glucose, a nitrogenous base (adenine) and three serially bonded phosphate group. ATP is often referred to by the term "energy currency" because it can be readily releasable in the bond between the third and second phosphate groups. Hydrolysis, which is the process of reducing ATP to energy, serves a wide range of cell functions including signaling and DNA/RNA synthesis. ATP synthesis uses energy from many catabolic mechanisms including cell respiration, betaoxidation, ketosis, and cellular metabolism.
Isomerism Definition Isomerism refers to the phenomenon where more than one compound has identical chemical formulas, but different chemical structures.
What are Monosaccharides? Monosaccharides are the most basic carbohydrates because they can’t be hydrolyzed to smaller carbs. They are the
Entropy is among the most important concepts that students should be able to comprehend clearly when learning Chemistry as well as Physics. In addition, entropy may be described in a variety of ways, which means it can be used in a variety of stages or scenarios, like the thermodynamics stage, in cosmic cosmology, or even in economics. The term "entropy" basically refers to the changes that occur spontaneously that take place in everyday phenomena as well as the general tendency to disorder.
mainly due to their ampholytic properties and biochemically mainly because they are protein constituents. An amino acid is a carboxylic acids that contain an aliphatic primary ammonium group in the same position as the carboxyl group. It also has a distinctive stereochemistry. Biosynthesis of proteins is done using 20 amino acids, which are subject to strict genetic control.
Proteins are the largest macromolecules in biology, found throughout every cell. They are also the most adaptable organic molecule in living system and is found in a many various kinds that range in size from small polymers to huge peptides. Proteins are polymers composed of amino acids, which are connected by peptide bonds. Proteins, the protein building blocks are the naturally occurring twenty amino acids. Proteins are, therefore, the multimers made up of amino acids.
the presence of an infinite amount of substrate and is therefore impossible to determine Km and Vmax from a hyperbolic graph. Due to this issue the equation of Michaelis-Menten was converted into an equation of straight lines using Lineweaver along with Burk.
Numerous carbohydrates, including glucose, meet their catabolic end in $ycolysis after being transformed into glycolytic intermediates. Most significant are glycogen and starch, which are storage polysaccharides that are either in cell walls (endogenous) or in the diet. The disaccharides are maltose. Lactose, trehalose. and sucrose, and the monosaccharides fructose and mannose and galactose.
Pyruvate is a component of the process of lactic acid and alcohol fermentation in anaerobic conditions. in an aerobic state, pyruvate loses carbon dioxide and hydrogen, and transform into Acetyl CoA and enter the TCA cycle. It can as well, enter the biosynthetic pathways. If there is a drop in levels of glucose, pyruvate goes into the gluconeogenesis process.
Glycolysis is the primary stage in the process of breaking down glucose in order to obtain energy to power the cell's metabolism. The majority of living organisms perform glycolysis as a part in their metabolic process. This process does not require oxygen, which is why it is considered anaerobic. Glycolysis happens in the cytoplasms of both eukaryotic as well as prokaryotic cells.
Glycolysis could not continue indefinitely if all NAD+ was used up and glycolysis would cease. Organisms must be capable of oxidizing NADH back into NAD+ in order to allow glycolysis to continue. The external electron acceptor will determine how this is done.
The term "carbohydrate" comes from the Greek word sakharon meaning "sugar". In the field of chemistry, carbohydrates comprise the most common type of organic compounds with simple structures. A carbohydrate is an aldehyde , or one that contains other hydroxyl groups. The most basic carbohydrates are known as monosaccharides. They have the fundamental structure (C*H2O)n where 3 or more is the minimum.
It is common to discuss fat as if it was a villainous substance that is bent to destroy our diets. However, they are beautiful tiny molecules composed of three hydrocarbon tails that are attached to a small coathanger-like molecule known as Glycerol. Similar to the other big organic molecules they perform crucial functions in the biology of both humans and other living things. (Also numerous recent diet studies suggest that sugar can cause many more health issues that fat!)
According to this hypothesis, only the first two bases of the codon have a precise pairing with the bases of the anticodon of tRNA, while the pairing between the third bases of codon and anticodon may Wobble (wobble means to sway or move unsteadily).
Mitochondrial transporter The mitochondria contain different types of transporter proteins within the intermembrane. These transporters transfers ADP, Pi, and H
The Electron Transport Chain is made of different protein complexes which perform a redox reaction to transfer electrons from electron donor to electron acceptor and also perform the transfer of protons from matrix to intermembrane space.
