A steroid compound (referred to as a sterol) has as its foundation a set of four hydrocarbon rings bonded to a variety of other atoms and molecules (see Figure 6b). Although both plants and animals synthesize sterols, the type that makes the most important contribution to human structure and...
Free fatty acids were annotated based on the exact mass of deprotonated molecules in MS1 scanning mode. * positive polarity: 184.0739 (C5H15NO4P + ) – LPC, PC, PC-O, PC-P; 18.0106 (NL H2O) – LPC; 141.0191 (NL C2H8NO4P) – LPE, PE, PE-P, PE-O; loss of the glycerol...

proteins and enzymes when they reach the stomach from contaminated foods. The stabilised metal compounds interact with cysteine’s sulphydryl groups (-SH) as well as methionine’s sulphur atoms (-SCH3), causing protein molecules to breakdown [18,20]....
Compared with small molecule drugs, it is easier to find molecules that inhibit the function of proteins [6]. Antisense oligonucleotide (ASOs) can act in two ways: Firstly, includes a DNA gap region flanked by chemically modified nucleotides to facilitate binding of complementary targets to ...
and to distinguish cells from one another by identifying previously unknown marker molecules on their surfaces. For example, monoclonal antibodies that react withcancerantigens can be used to identify cancer cells in tissue samples. Moreover, if short-lived radioactive atoms are added to these ...
Nassau (2001) comprehensively collates the various causes of colour in media, ranging from the chemical properties of atoms and molecules to physical optics. For example, he explains that the sky is blue (and the setting sun red) because atmospheric molecules scatter light of different wavelengths...
For other proteins, interactions or impaired interactions with chaperones, intracellular or extracellular matrixes, other proteins, small molecules and other endogenous factors can induce conformational changes and increase propensity to misfold. Often, misfolding and misfunction originate from point mutation(...
Curcumin is not soluble in water at acidic and neutral pH [8]. Due to interactions between acidic alpha hydrogens and basic molecules, the keto-enol structure of curcumin is formatted in the blood, a cardinal keto pattern in acidic and neutral solutions, and a stable enol pattern in ...
