<p>Tetragalacturonic acid (α-1,4 galacturonotetraose) is derived from pectin or pectic acid by enzymatic or partial acid hydrolysis (Combo, 2012). It is used in galacturonic acid metabolism research as a substrate to identify, differentiate, and characterize endo- and exopolygalacturonase(s), and gluconase(s) (Jayani, 2005). The addition of very short fragments of homogalacturonan, tri-galacturonate, and tetra-galacturonate oligosaccharides restores development in dark-grown, de-etiolated seedling mutants, suggesting that they are unable to generate de-methylesterified pectin fragments. A model of spatiotemporally separated photoreceptive and signal-responsive cell types has been proposed, that contains overlapping subsets of the regulatory network of light-dependent seedling development (Sinclair, 2017).</p>

<p>The objective of this project is to design a microcontroller-based system that can monitor and diagnose the level of damage in a composite material. The system will consist of an array of sensors, actuators, and microcontrollers that are connected by a wireless network. The sensors will measure the levels of damage at each point within the composite material. The actuators will provide feedback to the sensors, adjusting their frequency and amplitude based on the level of damage detected. Microcontrollers will be responsible for analyzing data from the sensors and diagnosing any faults in the system. A miniaturized dry skin patch could be used as an alternative to traditional wet skin tests for monitoring skin health.</p>

<p>Monofucosyllacto-N-hexaose II is a tetraol that is used as a reagent in the synthesis of enantioenriched and synthetically tetrasaccharidic products. Monofucosyllacto-N-hexaose II can be obtained by the reaction of Grignard reagents with glucose or by stereoselective reduction of an alpha, beta unsaturated ketone. The presence of the glucose residue in Monofucosyllacto-N-hexaose II makes it an acceptor for esterification reactions. This compound has chiral centers due to its two stereogenic centers at C2 and C3, which are both beta positions on the glucose residue. Monofucosyllacto-N-hexaose II also has a free hydroxyl group at C5 that can be esterified to produce chiral esters.</p>
