Lipids: A diverse group of organic compounds that play essential roles in the human body. There are several types of lipids, including triglycerides, phospholipids, sterols, and sphingolipids, each with distinct structures and functions. Triglycerides, the most common type of lipid, serve as a major energy source and storage form of fat in the body. They provide insulation and protection for organs, as well as serving as precursors for various hormones. Phospholipids are crucial components of cell membranes, forming a lipid bilayer that regulates the passage of molecules in and out of cells. Sterols, such as cholesterol, are important for cell membrane structure, hormone synthesis, and bile acid production. Sphingolipids are involved in cell signaling and cell recognition processes [22]. The advantages of lipids in the body are numerous. They provide a concentrated source of energy, with each gram of fat containing more than twice the calories of carbohydrates or proteins. Lipids also aid in the absorption of fat-soluble vitamins (A, D, E, and K) and help maintain healthy skin and hair. Additionally, lipids play a crucial role in cell signaling, serving as messengers that regulate various physiological processes in the body. Certain types of lipids, such as omega-3 fatty acids, have anti-inflammatory properties and are beneficial for heart health [7,54].

Despite their important functions, lipids can also have disadvantages when consumed in excess. High intake of saturated fats and trans fats, commonly found in processed foods, can lead to an increased risk of cardiovascular diseases, obesity, and other health issues. Excessive consumption of cholesterol-rich foods can contribute to the development of atherosclerosis and heart disease. It is essential to maintain a balanced diet that includes healthy fats, such as monounsaturated and polyunsaturated fats while limiting the intake of unhealthy fats to promote overall health and well-being. In conclusion, lipids are vital components of a healthy diet and play diverse roles in the human body [53,55]. Understanding the different types of lipids, their functions, advantages, and potential disadvantages can help individuals make informed dietary choices to support optimal health and well-being. By incorporating a variety of healthy fats into their diet and avoiding excessive consumption of unhealthy fats, individuals can harness the benefits of lipids while minimizing potential risks to their health as shown in Table 3.

Each type of chelating agent has specific characteristics that make them suitable for different applications. The primary function of chelating agents is to sequester metal ions and form stable complexes, thereby preventing the metal ions from participating in undesired chemical reactions [17,28]. Chelation can be used in various industries such as water treatment, food preservation, and pharmaceuticals to control the presence of metal ions and improve product stability. Chelating agents also find applications in medicine, where they are used to treat heavy metal poisoning by forming complexes with toxic metal ions and facilitating their excretion from the body. One of the key advantages of using chelating agents is their ability to enhance the stability and solubility of metal ions in solution. By forming stable complexes with metal ions, chelating agents can prevent the precipitation of insoluble metal salts and improve the efficiency of various chemical processes. Additionally, chelating agents can act as corrosion inhibitors by forming protective layers on metal surfaces, thereby extending the lifespan of equipment and infrastructure [60].

However, chelating agents also have certain disadvantages that need to be considered. One potential drawback is the environmental impact of chelating agents, as some compounds may persist in the environment and pose risks to ecosystems. Additionally, chelating agents can sometimes exhibit selectivity towards specific metal ions, which may limit their effectiveness in certain applications. Furthermore, the use of chelating agents in food and pharmaceutical products may raise concerns about potential health risks associated with prolonged exposure to these compounds. In conclusion, chelating agents play a vital role in various industries and applications by sequestering metal ions and forming stable complexes. Different types of chelating agents offer unique advantages and disadvantages, making them suitable for specific purposes. Understanding the properties and functions of chelating agents is essential for optimizing their use in different processes while minimizing potential risks.
