Proteinogenic amino acidProteinogenic amino acids are amino acids that are incorporated biosynthetically into proteins during translation. The word "proteinogenic" means "protein creating". Throughout known life, there are 22 genetically encoded (proteinogenic) amino acids, 20 in the standard genetic code and an additional 2 (selenocysteine and pyrrolysine) that can be incorporated by special translation mechanisms.
Smart materialSmart materials, also called intelligent or responsive materials, are designed materials that have one or more properties that can be significantly changed in a controlled fashion by external stimuli, such as stress, moisture, electric or magnetic fields, light, temperature, pH, or chemical compounds. Smart materials are the basis of many applications, including sensors and actuators, or artificial muscles, particularly as electroactive polymers (EAPs). Terms used to describe smart materials include shape memory material (SMM) and shape memory technology (SMT).
LookismLookism is the discriminatory treatment of people who are considered physically unattractive. It occurs in a variety of settings, including dating, social environments, and workplaces. Lookism has received less cultural attention than other forms of discrimination (such as racism and sexism) and typically does not have the legal protections that other forms often have, but it is still widespread and significantly affects people's opportunities in terms of romantic relationships, job opportunities, and other realms of life.
