“…Among the analyzed protein isolates, hemp protein exhibited the highest antioxidant activity, with ABTS and DPPH values of 9.37 TE/g and 9.01 TE/g, respectively (Table 2). The obtained results are consistent with those from previous studies, where hemp protein isolate exhibited comparable antioxidant activity levels [42]. Pumpkin seed and soy proteins also demonstrated notable antioxidant activities, indicating their potential to combat oxidative stress.…”

The study aimed to determine the phenolic content and antioxidant capacity of five protein supplements of plant origin. The content and profile of phenolics were determined using the UHPLC-DAD-MS method, while antioxidant capacity (ABTS and DPPH assays) and total phenolic content (TPC) were evaluated using spectrophotometric tests. In the analyzed proteins, twenty-five polyphenols were detected, including eleven phenolic acids, thirteen flavonoids, and one ellagitannin. Hemp protein revealed the highest individual phenolics content and TPC value (1620 μg/g and 1.79 mg GAE/g, respectively). Also, hemp protein showed the highest antioxidant activity determined via ABTS (9.37 μmol TE/g) and DPPH (9.01 μmol TE/g) assays. The contents of p-coumaric acid, m-coumaric acid, kaempferol, rutin, isorhamnetin-3-O-rutinoside, kaempferol-3-O-rutinoside, and TPC value were significantly correlated with antioxidant activity assays. Our findings indicate that plant-based protein supplements are a valuable source of phenols and can also be used in research related to precision medicine, nutrigenetics, and nutrigenomics. This will benefit future health promotion and personalized nutrition in the prevention of chronic diseases.

“…Some soluble proteins have antioxidant activity. It can neutralize reactive oxygen species generated by oxidative stress and adjust the intracellular redox balance [69], as well as reduce oxidative damage to cell membranes and intracellular organelle structures. Together, they maintain the stable growth and survival of woody plants under high-temperature conditions [70].…”

“…Moreover, it helps remove ROS, reduce the impact of oxidative stress, and protect the integrity of photosynthetic complexes and chloroplast membranes, thereby maintaining the normal progress of photosynthesis [67]. Similarly, high temperatures cause the accumulation of soluble proteins, enhance resistance to oxidative stress, reduce ROS damage to chloroplasts, and coordinate to respond to high temperature stress [69]. High-temperature stress affects the photosynthetic characteristics of woody plants by affecting the production of light and pigments, decomposing the generated light and pigments, damaging the photosynthetic reaction center structure and reducing the activities of enzymes involved in photosynthesis (Figure 3).…”

High-temperature stress is the main environmental stress that restricts the growth and development of woody plants, and the growth and development of woody plants are affected by high-temperature stress. The influence of high temperature on woody plants varies with the degree and duration of the high temperature and the species of woody plants. Woody plants have the mechanism of adapting to high temperature, and the mechanism for activating tolerance in woody plants mainly counteracts the biochemical and physiological changes induced by stress by regulating osmotic adjustment substances, antioxidant enzyme activities and transcription control factors. Under high-temperature stress, woody plants ability to perceive high-temperature stimuli and initiate the appropriate physiological, biochemical and genomic changes is the key to determining the survival of woody plants. The gene expression induced by high-temperature stress also greatly improves tolerance. Changes in the morphological structure, physiology, biochemistry and genomics of woody plants are usually used as indicators of high-temperature tolerance. In this paper, the effects of high-temperature stress on seed germination, plant morphology and anatomical structure characteristics, physiological and biochemical indicators, genomics and other aspects of woody plants are reviewed, which provides a reference for the study of the heat-tolerance mechanism of woody plants.
