Protein content
1.8 g of protein in 1 cup raw (63 g) of sugar snap peas, or 6.7 g for every 100 kcal it supplies.
Share of this food's calories that come from protein - it is moderately protein-dense.

One 1 cup raw, 1.8 g protein.
Every 100 kcal of sugar snap peas brings 6.7 g of protein. On that measure it ranks 36th of the 105 vegetables in this database and 369th of all 796 foods on the site. Measured by weight instead, its 2.8 g per 100 g ranks 25th in its group.
Around 27% of the calories in sugar snap peas come from protein, so it is moderately protein-dense. It contributes to a day's protein total, but the bulk of what it delivers is energy rather than amino acids - treat it as a contributor alongside a denser source, not as the protein in a meal.
USDA lists 0.2 g of fat per 100 g of sugar snap peas, too little for a protein-to-fat ratio to mean much.
Set against alfalfa sprouts, another vegetable entry in the database, a serving carries about 0.5 g more protein (alfalfa sprouts has 1.3 g per 1 cup).
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 measured by volume at 63 g, and it covers about 4% 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 | 0.228 g | 0.14 g | 81 |
| lysine | 0.202 g | 0.13 g | 72 |
| valine | 0.273 g | 0.17 g | 98 |
| isoleucine | 0.161 g | 0.1 g | 58 |
| threonine | 0.099 g | 0.06 g | 35 |
| phenylalanine | 0.09 g | 0.06 g | 32 |
| methionine | 0.011 g | 0.01 g | 4 |
| histidine | 0.017 g | 0.01 g | 6 |
| tryptophan | 0.027 g | 0.02 g | 10 |
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
2.8 g. The 1 cup raw serving used on this page weighs 63 g and so carries 1.8 g.
6.7 g. That figure divides its 2.8 g of protein per 100 g by its 42 kcal per 100 g, so it does not depend on serving size.
No. On its own, the protein in sugar snap peas is short of at least one essential amino acid; other protein sources across the day fill the gap.
About 4%. One 1 cup raw serving has 1.8 g, and the FDA Daily Value for protein is 50 g.
