“…As we know, amino acids are amphoteric organic molecules, which can form the corresponding conjugate acid or base by the addition or removal of protons, respectively. , Therefore, the electronic properties of SWCNTs can be tuned by using the same amino acid with different types. Lys was chosen because of its simple structure and SWCNT/Lys showed high PF.…”

Many drugs, foods, and clothes are derived from natural products; however, little attention has been focused on natural-derived thermoelectric (TE) materials. In this work, several natural amino acids are first introduced to single-walled carbon nanotubes (SWCNTs) and a series of environment-friendly n- and p-type freestanding SWCNT/amino acid films are fabricated as potent TE materials. Among the composites, SWCNT/histidine (His) and SWCNT/lysine (Lys) achieve excellent n-type TE properties, with the highest power factors of 508.5 and 502.0 μW m–1 K–2 at room temperature, respectively. SWCNT/aspartic acid (Asp) displays p-type behaviors, with the highest power factor of 221.6 μW m–1 K–2 at room temperature. Moreover, a TE device based on SWCNT/Lys and SWCNT/Asp including five p–n junctions is fabricated. The high open-circuit voltage (42.3 mV) and output power (4.3 μW) are obtained at ΔT = 87 K. Given the excellent TE performance, green composites based on natural-derived materials can be the promising candidates for TE devices.

L-lysine is an essential amino acid not synthesized by the body and is used as a nutritional supplement, and is considered an index of the nutritional quality of foodstuffs. The level of L-lysine consumption depends on age, where an imbalance in L-lysine levels can cause certain disease conditions. This study identified the effects of L-lysine contained in food supplements using the yeast-based amperometric biosensor Saccharomyces cerevisiae, which measures dissolved oxygen (DO) levels due to cellular respiration of yeast with an analyte assay sample. The measurements were made by calibrating pure L-lysine at 100, 200 and 300 mM concentrations. The results show that the higher the concentration of L-lysine, the smaller the level of DO remaining detected, where the percentage range of DO is 13.47% - 26.02%. The dietary supplement sample test, namely Curcuma Plus, has an error of 1.01% which states that the biosensor used can detect L-lysine levels in samples with high sensitivity and selectivity and can be applied to the food and health industries. The measurement results are clustered using Principal Component Analysis (PCA) to see the resulting clusters and data patterns.

“…As regards the serum metabolome, exposure to PFOA altered metabolites involved in different physiological functions in lean and obese mice. The amino acids altered include Llysine that is involved in calcium absorption and is a precursor in the synthesis of carnitine and was decreased by PFOA exposure in lean mice (Pundir et al, 2021). Serine is precursor of glycine and cysteine and is involved in biosynthesis of purines and pyrimidines, sphingolipids and mitochondrial metabolism (de Koning et al, 2003;Gao et al, 2018).…”
