casein
Sign in to saveCasein ( ; from Latin caseus, 'cheese') is a family of related phosphoproteins (αS1, aS2, β, κ) that are commonly found in mammalian milk, comprising about 80% of the proteins in cow's milk and between 20% and 60% of the proteins in human milk. Sheep and cow milk have a higher casein content than other types of milk with human milk having a particularly low casein content.
AI overview
Casein is a group of proteins that make up the majority of protein found in mammalian milk, accounting for about 80% of cow's milk protein but a much smaller portion (20-60%) of human milk protein. It matters because it's a major nutritional component of milk and affects the properties of different milk types, with cow and sheep milk being particularly casein-rich compared to human milk.

Casein does not appear to be essential in mammals. For example, the β-casein gene can be deleted in mice. The resulting mice are healthy and fertile, but the growth of their pups is reduced. Similarly, mice lacking the κ-casein gene are healthy, but they did not suckle their pups and failed to lactate, hence the gene is required for reproductive success.
