Study Notes

Cellulose acetate is a synthetic form of cellulose with properties such as good chemical resistance, high porosity, and high flow rate, making it suitable for use in household water filters.
Cellulose acetate is a low-cost material, making it accessible for use in household applications.
Other cellulose materials such as paper, cotton, and wood fibers can also be used, but cellulose acetate is the most used due to its favorable properties for water filtration applications.
Polyhydroxyalkanoates (PHA) are a class of biodegradable and biocompatible polyesters produced by microorganisms, such as bacteria and fungi, and are a type of bioplastic.
PHAs are made from renewable resources, such as sugar and cornstarch, and are an environmentally friendly alternative to traditional petroleum-based plastics.
PHAs have several properties that make them ideal for use as bioplastics, including biodegradability, biocompatibility, and a high degree of polymerization.
Biosensors have several advantages, including high sensitivity, specificity, rapid response time, portability, and cost-effectiveness.
Biosensors can detect target analytes at low concentrations, can be designed to specifically recognize a target analyte, provide results in real-time, can be designed to be small and portable, and can be manufactured cheaply.
Biosensors have some limitations, including stability issues due to environmental conditions, interference from other substances in the sample, and the need for frequent calibration.
Enzymes, such as lipase, catalase, trypsin, and ATP synthase, play a critical role in many biological processes and their dysfunction is involved in developing many diseases.
Proteins, such as hemoglobin, albumin, transferrin, apolipoproteins, ferritin, and glut transporters, play a critical role in many biological processes and their dysfunction is involved in developing many diseases.
Proteins are essential nutrients that provide the body with amino acids, which are the building blocks of the body's tissues.
Proteins are found in many foods, including meat, poultry, fish, dairy products, beans, lentils, tofu, and eggs, and are a vital component of a healthy diet.
The quality of proteins in food is determined by the types of amino acids they contain, as well as the amount of each type of amino acid.
Meat analogs, also known as meat substitutes or meat alternatives, are plant-based foods designed to mimic the taste, texture, and appearance of meat.
Meat analogs are made from various ingredients, including soy protein, wheat protein, pea protein, and other plant-based ingredients, and are often fortified with vitamins and minerals.
Meat analogs are a popular alternative to meat for many people, including vegetarians, vegans, and those who are looking to reduce their meat consumption for health or ethical reasons.
Examples of meat analogs include tofu and tempeh, which can be used in various dishes, including stir-fries, salads, and smoothies.
