Protein content
1.5 g of protein in 1 medium (142 g) of nectarine, or 2.4 g for every 100 kcal it supplies.
Share of this food's calories that come from protein - it is more of an energy food than a protein food.
| Protein per 100 kcal | 2.4 g |
|---|---|
| Protein per 100 g | 1.06 g |
| Protein per serving | 1.5 g in 1 medium (142 g) |
| Calories from protein | 10% |
| Leucine per serving | 0.02 g |
| Rank in fruits, per 100 kcal | 9th of 71 |
| Rank of all foods, per 100 g | 726th of 796 |
| Share of 50 g Daily Value | 3% per serving |
| Protein quality | Incomplete protein |
One 1 medium, 1.5 g protein.
Every 100 kcal of nectarine brings 2.4 g of protein. On that measure it ranks 9th of the 71 fruits in this database and 655th of all 796 foods on the site. Measured by weight instead, its 1.06 g per 100 g ranks 29th in its group.
Only about 10% of the calories in nectarine come from protein, so it is more of an energy food than a protein food. It is worth eating for other reasons; the protein it adds to a day is incidental.
USDA lists 0.32 g of fat per 100 g of nectarine, too little for a protein-to-fat ratio to mean much.
Set against avocado, another fruit entry in the database, a serving carries about 0.5 g less protein (avocado has 2 g per 1/2 fruit).
It is an incomplete protein on its own; pairing it with other plant foods across the day covers the full range of essential amino acids. The serving quoted here is counted by piece at 142 g, and it covers about 3% of the 50 g FDA Daily Value for protein.

Portion weights are the household measures listed on the USDA record; protein and calories scale from the per-100 g figures.
Amino acids
| Amino acid | Per 100 g | Per serving | mg per g protein |
|---|---|---|---|
| leucine | 0.014 g | 0.02 g | 13 |
| lysine | 0.016 g | 0.02 g | 15 |
| valine | 0.013 g | 0.02 g | 12 |
| isoleucine | 0.009 g | 0.01 g | 8 |
| threonine | 0.009 g | 0.01 g | 8 |
| phenylalanine | 0.021 g | 0.03 g | 20 |
| methionine | 0.006 g | 0.01 g | 6 |
| histidine | 0.008 g | 0.01 g | 8 |
| tryptophan | 0.005 g | 0.01 g | 5 |
Per-100 g values are the amino acid analysis on the USDA record. The serving and per-gram-of-protein columns are arithmetic on those values; they are not a protein quality score.

Quick answers
1.06 g. The 1 medium serving used on this page weighs 142 g and so carries 1.5 g.
2.4 g. That figure divides its 1.06 g of protein per 100 g by its 44 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in nectarine is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 3%. One 1 medium serving has 1.5 g, and the FDA Daily Value for protein is 50 g.
