<p>A solar thermal collector is a device that absorbs the sun's heat, or thermal energy, and converts it to useful heat energy. It consists of a dark-colored surface (usually metal) that absorbs sunlight and transfers the heat by radiation to a fluid such as water or oil, which then carries the heat away for use. The efficiency of this type of collector depends on the quantity of sunlight that reaches it, the temperature difference between the hot fluid and ambient air, and its design. A typical solar thermal collector has an efficiency of about 10%.</p>

<p>Fucose (Fuc, 6-deoxy L-galactose) has a methyl group at C6 in place of a hydroxyl group and this gives the molecule a greater degree of hydrophobicity than galactose (Collins, 2006). L-fucose is found in fucoidan, a polysaccharide that occurs in the brown seaweeds (Phaeophyceae) (Percival, 1967). Fucose is also a key component in many mammalian N- and O-linked glycans, glycolipids, blood group substances and Lewis antigens (Becker, 2003). In human milk, neutral (fucosylated) oligosaccharides (HMO) contain fucose at the terminal position (e.g. 2’ -fucosyllactose and lactodifucopentaose). They represent 35% to 50% of the total HMO content and many in vitro studies suggest that HMOs directly modulate immune responses, acting either locally on cells of the mucosa-associated lymphoid tissues or systemically to inhibit the expression of inflammatory genes, mainly cytokines (Plaza-Diaz, 2018).</p>

<p>Sugars formed by photosynthesis are essential for plant’s nutrition and they can be carried by a sophisticated system called phloem from the leaves to the root tips. Since the phloem is a delicate tissue composed of various specialized cell types, the study of its structure and functions remains a challenging task. Recently, fluorescent coumarin glucoside derivatives, including esculin (Plant Physiology 2015, 1211-1220) have been used as phloem probes. Among the probes tested, only esculin and fraxin are transported, while skimmin is not, suggesting a certain specifity of natural coumarin glucosides for the transporter AtSUC2.</p>

<p>Estradiol 3-sulfate 17b-glucuronide dipotassium salt is an estradiol ester that is a metabolite of estradiol. It has been shown to be an intermediate in the synthesis of estrone sulfate and other steroid hormones. Estradiol 3-sulfate 17b-glucuronide dipotassium salt is formed from estradiol by the addition of one molecule of sulfuric acid followed by the addition of glucuronic acid, which results in a salt form. It may also be formed by oxidation of allylic hydroperoxides and photooxygenation in families with oxygenated moieties. Irradiation leads to formation of oxygenated steroids. The alkene reactivity depends on the substitution pattern, the cyclic reactivity depends on the ring size and substitution pattern, and the reactivity with peroxides depends on the position of substitution.</p>

<p>Myo-inositol 1,2,4,5,6-pentakisphosphate (IP) is a phosphate of inositol that is found in the cytosol. It is an important component of polyphosphates and can be used for oxygen transport. It has been shown to inhibit the growth of cancer cells by binding to monoclonal antibodies that are targeted against CD20 and CD22 on cancer cells. IP also inhibits the activity of kinases and phosphatases in mammalian cells. This may be due to the inhibition of cytokine release from macrophages treated with IL-1β. Inositol phosphates are involved in many cellular responses including platelet-derived growth factor activation, cell proliferation, and protein synthesis.</p>
