  • 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.
    Amino Acids EAR RDA
    phenylalanine + tyrosine 27 33
    valine 19 24
    threonine 16 20
    tryptophan 4 5
    methionine + cysteine 15 19
    leucine 34 42
    isoleucine 15 19
    lysine 31 38
    histidine 11 14
  • Amino Acid Requirements for Adults

    Estimates of Amino Acid Requirements for adultsmg / kg per day

    • Phenylalanine + tyrosine: 14
    • Leucine: 14
    • Methionine + cystine13
    • Histidine: 8–12
    • Lysine: 12
    • Isoleucine: 10
    • Valine: 10
    • Threonine: 7
    • Tryptophan: 3.5

  • 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 .

Now I can look at you in peace; I don't eat you any more.


 A tree is a plant with an elongated stem, or trunk, supporting branches and leaves in most species. Trees tend to be long-lived, some reaching several thousand years old. Trees have been in existence for 370 million years.

A variety of plant species have independently evolved a woody trunk and branches to compete for sunlight. In more general sense, tall palms, tree ferns, bananas and bamboos are also trees. The roots branch out under the ground to anchor the tree and to extract moisture and nutrients from the soil. Above ground, the branches usually bear leaves, which capture light. 

Trees reduce erosion and moderate the climate. Trees and forests provide a habitat for many species of animals and plants. Some trees provide edible fruit Apple
