A nutrient is a molecule you must have, but the body cannot manufacture. You have to ingest (eat) it. If you don't have it, at first you will not feel well. It you don't get it for a longer time, you will begin to feel sick. If you don't get it for too long a time you are probably going to die.

Each ounce of honeybee pollen contains just 28 calories. Only 7 grams are carbohydrate, plus 15% Lecithin, the substance that burns away fat and 25% is pure protein. 

Twenty-eight minerals are found in the human body. Fourteen are vital, essential elements present in such small amounts that they are called - "micro- nutrients." Honeybee pollen contains all 28 minerals:
Nucleosides
Guanine
Hexodecanol
Auxins
Xanthine
Alpha-Amino-Butyric Acid
Brassins
Hypoxalthine
Monoglycerides
Gibberellins
Crocetin
Diglycerides 
Kinins
Zeaxanthin
Triglycerides
Vernine
Lycopene
Peutosaus

Calcium. 1 - 15% of ash
Phosphorus 1-20% of ash
Iron, 1-12% of ash
0.01-1.3% of fresh pollen
0.6-7.1 mg % of air dried
Copper 05-08% of ash
1.1-2.1 mg % of fresh
Potassium, 20-45% of ash
Magnesium, 1-12% of ash
Manganese, 1.4% of ash, 0.75 mg %
Silica, 2-10% of ash
Sulphur, 1% of ash 
Sodium - Titanium-Zinc

Fatty Acids (Conifer Pollen)
Total list identified are:
Caproic (C-6) - Caprylic (C-8)
Capric (C-10) - Lauric (C-12)
Myristic (C-14) - Palmitic (C-16)
Palmitoleic (C-15) one double bond

Pseudotduga dry pollen contains
0.76-0.89 % fatty acid. Major are:
Oleic, Palmitic, Linoleic, 
Pinus dry pollen contains: 
125-1.33% fatty acid based on 
dry weight of pollen, major are: 
Linolenic, Oleic - Stearic.

 Fats & Oils:

 - 5% Fatty acid (may be 5.8%) Hexadecanol may be 0. 14% of pollen by weight. Alpha-amino butyric acid is present in pollen fat. Unsaponifiable fraction of pollen may be  2.6% by weight. 

Water: 

-20% of fresh pollen 

Miscellaneous:

Waxes, Resins, Steroids, Growth Factors, Growth Isorhanetin, Vernine, Guanine, Xanthine, Hypoxanthine, Nuclein, Amines, Lecithin, Glucoside of Isorhanstin, Glycosides of Quercetir, Selenium, Nucleic acids flavonoids, phenolic acids, tarpenes & many other yet undefined nutrients.  

Proteins, Globulins, Peptones, and Amino Acids:

7-35%. average 20%: 40-50%  may be free amino acids: 10-13% consists  of amino acids in dry pollen. 35 grams of pollen per day can satisfy the  protein requirements of man. 25 grams of  pollen per day can sustain man because it  contains 6.35 grams as indicated by Rose.   

Plus other amino acids: 

Pollen contains the same number of amino acids, but vary greatly in quantity of each: Tryptophan 1.6% - Leucine 5.6% Lysine 5.7% - Isoleucine 4.7% Methionine 1.7% - Cystine 0.6% Thresonine 4.6% - Arginine 4.7% Phenylalanine 3.5% - Histidine 1.5% Valine 6.0% - Glutamic acid 2.1% Tyrosine - Glycine - Serine - Proline - Alanine - Aspartic acid Hydroxyproline - Butyric Acid.​​​
