  • EAR and RDA for Amino Acids

    Estimated Average Requirement (EAR) and Recommended Dietary Allowance (RDA) for amino acids (protein) for healthy adults 19 y and older, mg/kg/day:

    • Estimated Average Requirement (EAR): average, estimated to meet the requirements of 50%.
    • Recommended Dietary Allowance (RDA): average, sufficient to meet the nutrient requirements of nearly all.

  • Phenylalanine

    Phenylalanine is an essential amino acid.

    Provided by diet, phenylalanine can be converted into another amino acid, tyrosine, in the body. Tyrosine is used to synthesize two key neurotransmitters that promote alertness: dopamine and norepinephrine. 

    It has 3 forms:

    • D-phenylalanine;
    • L-phenylalanine - most common, the form in which phenylalanine is incorporated into the body’s proteins;
    • DL-phenylalanine.

  • All Essential Amino Acids

    An essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized by the organism, and must be supplied in diet. 

    The 9 amino acids humans cannot synthesize (F V T W M L I K H):

    • phenylalanine
    • valine
    • threonine
    • tryptophan
    • methionine
    • leucine
    • isoleucine
    • lysine
    • histidine

    Animal and plant proteins are made up of about 20 common amino acids.

    Synthesis of 6 other amino acids - conditionally essential - can be limited under special conditions (R C G Q P Y)arginine, cysteine, glycine, glutamine, proline, and tyrosine.

    Dispensable amino acids can be synthesized in the human body, 5 (A D N E S): alanine, aspartic acid, asparagine, glutamic acid and serine .

Never let your sense of morals prevent you from doing what is right.

Ethics and Aesthetics

Ethics - moral principles that govern behavior of a person or a group.

Ethics can refer to standards of right and wrong that prescribe what a human ought to do. Ethical standards include standards relating to rights (e.g. right to life, the right to freedom from injury).

Laws, and social norms, or feelings can differ from what is ethical. It is necessary for individuals to frequently examine own standards to ensure that they are reasonable. 

Ethics as moral philosophy involves systematizing, defending, and recommending concepts of right and wrong conduct. Moral philosophy is related to the fields of moral psychology, descriptive ethics, and value theory.

As a branch of philosophy, ethics investigates the questions

  • "What is the best way for people to live?
  • "What actions are right or wrong in particular circumstances?"

Axiology is the philosophical study of value, collective term for ethics and aesthetics - philosophical fields that depend crucially on notions of worth. 

Aesthetics studies the concepts of "beauty" and "harmony." Aesthetics (esthetics) is a branch of philosophy dealing with the nature of art, beauty, and taste, creation and appreciation of beauty. It is more scientifically defined as the study of sensori-emotional values. More broadly, aesthetics is defined as "critical reflection on art, culture and nature."
